General Safety Information from Stickers:

• In case of maintenance, adjustments and repair, always switch OFF the engine of the towing vehicle and the PTO. Prevent the combination from driving and/or sliding away.
• Keep a distance of minimum 4 metres if the machine is operating (except the operator sitting in the towing vehicle).
• During operation, NO persons are allowed within the danger zone of the machine, because there is danger of physical injuries caused by moving components.
• Prior to using the machine, the operators of the machine must read the user manual carefully.
• BE CAREFUL not to get any parts of your body jammed when opening the rear cover!
• You can operate the machine safely, if the PTO does not exceed 500 rpm.
• The back cover must always be closed and undamaged during operation of the machine!

4.0 PTO

The PTO is a very important item. It drives the machine from the tractor and ensures the safe operations when correctly maintained and installed. The PTO shaft has its own CE certification. Read the PTO shaft manual, which is connected to the shaft itself. For specific adjustments see the details given on the PTO page in the parts book. Do not exceed the given values. This can lead to an unsafe situation and overload the machine, resulting in damage.

Diagram Description: The diagram shows the PTO shaft connection and dimensions. It illustrates the relationship between the tractor PTO shaft and the Verti-Drain PTO shaft, including measurements for length and overlap.

Diagram Labels:

• A: Tractor PTO shaft
• B: Verti-Drain PTO shaft
• 250mm (9.8") min.: Minimum overlap length

4.1 PTO LENGTH

The length of the PTO is very important. When too long, the transmission of the tractor and/or VERTI-DRAIN may be damaged. When the overlap length of the tubes drops under 250 mm (9,8") anytime, the PTO may be damaged.

* The length changes when the machine is raised or when another tractor is used.

To cut the standard PTO from new or for another tractor, work as follows (see fig. 3):

1. Measure the distance between tractor PTO shaft and VERTI-DRAIN PTO shaft from groove to groove when machine is on the ground at correct angle and attached to the tractor.
2. Measure the length B of the PTO in its shortest position from lock pin to lock bolt.
3. Split PTO in two pieces and remove safety cover from each end.
4. Both tubes and safety cover ends should be shortened: (B - A) + 125 mm (4,9").
5. Deburr all items, use some grease and put all parts together.
6. Assemble the slip clutch side of the PTO to the VERTI-DRAIN transmission.
   * Torque for lock bolt should be 80 Nm (700 lb.in.) and checked every 40 hours.
7. Connect other side to the tractor.
8. Check overlap of tubes.
9. Never run machine with a damaged PTO safety cover. Replace it first.

4.2 USE OF PTO

For the correct use of the PTO, the following items need to be checked:

1. During work the angle of the joints may never exceed 30 degrees.
2. The joints have to be in line all the time.
3. The tube overlap should always be minimal 250 (9,8") mm.
4. Never use the machine with a damaged PTO protection cover.
5. For greasing see par. 13.0 Maintenance.

Diagram Description: Figure 3 shows the PTO connection with the tractor, illustrating the correct angles and alignment. Figure 5 shows the working depth adjustment mechanism.

Diagram Labels (Fig. 3):

• 1: PTO shaft
• 2: Universal joint
• 3: Safety cover

Diagram Labels (Fig. 5):

• 1: Clamping handles / bolts
• 2: Depth setting label
• 3: Spindles

5.0 WORKING DEPTH ADJUSTMENT

The working depth can be adjusted when the machine is in a lifted position, see fig. 4. Loosen the clamping handles / bolts 1 on both sides of the machine. Then turn the spindles 3 in or out. Each rotation is 4 mm (0.160”). The label (2) on the side of the machine indicates the depth setting. After having reached the correct working depth, retighten the clamping handles / bolts 1.

@Never adjust one side more than 4 turns. Compensate the other side first before proceeding.

@The adjustment can be done with a special tool in the machine tool box. The value at the decals is only true when 350 mm (13,8") long tine are used. When shorter tines are used, deduct the length difference to the 350 mm (13,8") from the actual decal reading.

@Clean and spray the spindle and nut with anti-sticking grease oil every 100 hours, to prevent dirt sticking on the nut.

6.0 TINE ANGLE ADJUSTMENT

All pins can simultaneously be adjusted with 2 handles 1 located on both sides of the machine; see fig. 5. Lift the machine above the ground and loosen clamping handle / bolts 2 on both sides of the machine. Adjust the angle by turning the handle 1. The angle can be read on the label 3. Then retighten the clamping handle / bolts 2.

@An angle of 90 degrees means almost no tine movement in the ground. This is required for hollow coring tines and advised for thinner tines.

@From 90 to 65 degrees means more "kick action". This is advised for solid tines, depending on ground conditions, tine size and customer requirements.

@The angle of 90 degrees means that the tines penetrate perpendicular into the ground. This is only true if the machine is correctly set, see fig. 1. If this isn't correct a push force F, see fig 5. is applied, which can seriously damage the machine.

@The length of the draw rod assembly should be 475.0 mm (18.7"), which can be set by the calibrating shims, see the spare part page.

Diagram Description: Figure 6 shows a graph illustrating the relationship between ground speed, gear setting, and hole spacing. It also includes a diagram of the machine's draw rod assembly.

Diagram Labels (Fig. 6):

• V: Ground speed (mph, km/h)
• D: Hole distance (mm, inches)
• PTO 300-500 rpm
• 3, 2, 1: Gear settings

7.0 GROUND SPEED

The ground speed determines the hole spacing D in the drive direction, see fig.6. The VERTI-DRAIN doesn't need a creeper gear, however if the customer wants a close hole spacing, the ground speed should be low enough, which depends on the tractor.

The gearbox has standard three different gear setting, resp. 1,2 and 3. When set in 3, reduce PTO revs till 400 rpm's max, otherwise damage may occur. The input speed R on the PTO may be maximum 500 rpm. When stones or rocks are expected, the input speed should be lowered.

With heavier tines or attachments, the tine holders may start to float. Lower rpm's at that time, before the tine holders start to turn upwards.

In Fig.6., a graph is drawn in which the relation between the ground speed, the gear setting and the hole spacing is given. If the tractor ground speed is known at 500 rpm's of the PTO, the hole spacing can be determined at different gearbox settings.

@ If the machine is not set correctly behind the tractor, see fig.1., different angles at the PTO may cause vibration into the drive line of the VERTI-DRAIN. This vibration can hurt the machine and also the performance of the holes in the ground.

@If changing gear is difficult; the crankshaft should be turned a little.

@ If the PTO shaft is incorrectly fitted (too long or too short), extra forces are applied to the input shaft of the gearbox. Damage may occur.

* When the gearbox is shifted, shut off the tractor engine.

Diagram Description: Figure 7 illustrates the starting procedure for the Verti-Drain, showing the sequence of operations from lowering the machine to engaging the PTO and moving forward.

Diagram Labels (Fig. 7):

• A: Start moving forward
• B: Engage PTO
• C: Lower machine into the ground

8.0 STARTING PROCEDURES

The starting procedure is VERY important. If the start up is not done as described hereunder. serious damage to the machine may occur. Proceed as follows, see fig.7.:

1. Drive to the spot you want to start the operation.
2. Lower the machine, till the lowest tines are almost on the ground.
3. Set tractor engine at aprox. 1200 rpm's.
4. Put tractor in correct gear, and start moving forward (A).
5. Engage PTO at tractor (B).
6. DURING rolling forwards with the machine RUNNING, GENTLY lower the machine in the ground (C), till front roller is tight on the ground.
7. Increase engine rpm's till the maximum value permitted.

At the end of a pass, quit the operation as follows:

1. Lower engine rpm's till about 1200.
2. Raise machine out of the ground.
3. As soon as all tines are out of the ground, disengage PTO.
4. Raise machine further, till the lowest tines are at least 120 mm (5") above the ground.
5. Move to the next spot and start again as described above.

@ It is absolutely necessary to proceed as described above. If the machine is put into the ground first, without the PTO running, serious damage may occur.

@The machine needs to be lowered GENTLY.

@Be careful with driving backwards.

During work the front roller needs to be stable on the ground. If the machine starts to be unstable, change the rpm's on the PTO. If this doesn't make any difference, adjust the working depth or change to other tines that penetrate easier.

@ If nothing is done on the instability of the machine, serious troubles may arise afterwards. The machine is NOT protected against these circumstances on the long term.

@ NEVER drive backwards with the tines in or close to the ground.

@Do not uses a hydraulic top link.

9.0 GENERAL USAGE OF VERTI-DRAIN

The VERTI-DRAIN can only be used when the circumstances are right. Check the following items:

1. Are there any loose objects on the field? If so, these must be removed first.
2. Are there any slopes? The maximum slope for the VERTI-DRAIN is 20 degrees. Always operate the VERTI-DRAIN from the top to the bottom of a slop.
3. Are there any pipes/wires/cables in the ground? If so, ascertain at what depth and set the working depth at a maximum of 60% of the pipe etc. depth.
4. Are there any hard objects in the ground? If so, operate the VERTI-DRAIN with a very low PTO speed, or adjust working depth.
5. Is there any danger of flying objects such as golf balls, which could distract the attention of the driver? If so, the VERTI-DRAIN cannot be operated at that moment.
6. Is there any danger of subsidence or land/mud slides? If so, the VERTI-DRAIN cannot be operated on the field at that moment.
7. Is the ground frozen or very wet? Postpone operation till circumstances are better.
8. When ground is very compacted, use shorter thinner tines to penetrate, or adjust working depth.

10.0 TRANSPORT OF VERTI-DRAIN

The user is responsible for the transport of the VERTI-DRAIN behind the tractor along the public streets. Check on the national legislation's. Across open ground a maximum speed of 12 km/h (8 mph) applies. In view of the weight of the VERTI-DRAIN, a higher speed could be dangerous for the driver and bystanders. The machine could also suffer damage due to jolt, which can occur with higher speeds.

* At least 20% of the tractor weight should rest on the front axle when machine is lifted.

11.0 UNCOUPLING OF THE VERTI-DRAIN

The machine can be disconnected from the tractor as follows:

1. Open the rear cover.
2. Turn the crankshaft until both central pin holders right/left of the gearbox are in their top positions.
3. Turn all other tine holder upwards against the stop.
4. Lower the machine on a firm surface.
5. Lock pin into a corresponding hole, see fig. 1.
6. Block the rear and front roller against rolling away.
7. Remove the top link.
8. Disconnect the PTO shaft from the tractor side.
9. Disconnect the lower three point linkage arms.

* Shut down the tractor engine during walking around the VERTI-DRAIN.

* In case of storing the machine for a long period, it is recommended NOT to fold up the pins in view of the life span of the of the shock-absorber springs.

12.0 PROBLEM ANALYSIS

13.0 MAINTENANCE

14.0 TECHNICAL INFORMATION

Generally speaking, this Verti-Drain is not a complicated machine. A couple of technical items will be explained. If you still have questions, please contact your dealer, who is willing to assist you.

Diagram Description: Figure 8 shows a detailed diagram of various components of the Verti-Drain, with torque settings indicated for specific bolts and nuts. It also shows angles and measurements related to the machine's assembly and operation.

Diagram Labels:

• A, B, C, D, F, G, H: Various connection points and components.
• Torque values are given in Nm (lbf.ft) and Loctite recommendations are provided.

14.1 TORQUE SETTINGS

In fig.8., the torque settings of the most important bolts/nuts are given. For the ones the torque setting is not mentioned, please be sure that they are tightened as a similar size bolt/nut would be tightened. If bolts/nuts are working themselves loose, Loctite may be applied.

14.2 THE CRANKSHAFT

In fig.9. the assembly of the crankshaft is given. Also look at the spare part page for a more clear view and setup. On a 7416 the angle between the handles on the gearbox should be 60 degrees.

Diagram Description: Figure 9 shows a top view of the crankshaft assembly, illustrating the arrangement of various parts and their connections.

Diagram Labels:

• II, IV, V, VI, VII, VIII, IX, X, XI: Various components of the crankshaft assembly.

14.2.1 REPLACING THE TRANSMISSION OIL SEAL

In fig.9. a top view of the crankshaft is given. To replace an oil seal at the transmission, handle as follows:

1. Loosen nuts II and IV, which may be tight through the Loctite. Some heat may help.
2. Remove big end V, after the big end pin XI is removed.
3. Remove cover III by unscrewing all the bolts/nuts.
4. Slide crank VI away from the gearbox using a hammer and hitting is slightly at the centre, until big end pin VII is free.
5. Rotate crank VI and slide big end IX from the big end pin VII.
6. Remove handle X after marking the position and removing nut VIII.
7. Pull oil seal out with a screwdriver.
8. Clean area and assemble new oil seal.
9. Clean handle X and splined shaft and assemble the handle at the right position.
10. Before attaching nut/new lock plate, first fill the space under the locking plate (between the splines and the handle) with liquid silicon paste.
11. Attach a new locking plate and nut VIII. Use Loctite for the nut as well.
12. Assemble the other parts the same way as they have been removed.
13. If the crankshaft seems lumpish, see further 14.2.3.

14.2.2 REPLACEMENT OF A CRANK WITH BEARING

Replacing a crank is necessary when it is cracked or when the big end nuts start to come loose on a regular base. Either the crank bearing, the crank bearing fitting or the big end pin holes in the crank are damaged. Replace the crank / bearing as soon as possible, to avoid any more damage to other parts, as follows:

1. Remove big end pin nuts IV (or II) from both big end pins connected to the crank.
2. Remove the big end pins, so that the big end can be swapped away. (Note; this will not happen with the big end (pin) aside the gearbox.).
3. Remove the crank bearing covers III.
4. Tap crank IV and bearing carefully side wards out of the frame by hitting the crank in the centre with a hammer.
5. Remove the bearing carefully from the crank.
6. After replacing the crank and/or bearing, replace the parts in the same sequence as they were removed. Use Loctite were indicated in fig.8.
7. If the crankshaft runs tight, see 14.2.3.

14.2.3 REMOVING THE CRANKSHAFT TENSION

If parts have been replaced on the crankshaft, the crankshaft may seem running tight. This is because of possible tension in the crankshaft parts. It is necessary to remove these, as follows, see fig.9.:

1. Tap the centre of the crank adjacent to the gearbox, alternately left and right.
2. Feel whether the crank moves and continue till the crank has nested.
3. Repeat this operation with the adjacent crank and continue this way till the crankshaft will operate more smoothly.

@After any repair on the crankshaft, the crankshaft nuts should be checked regularly, see 12.0.

@Don't assemble the cranks at the wrong side of the machine. See the spare-part part for the right part numbers.

14.3 ALIGNMENT OF AN ELEMENT

In the event that an element is no longer in line with the adjacent elements, the alignment can be corrected as follows (see fig.8.):

• Slacken the four bolts/nuts A, that connect the crankshaft to the element.
• Slacken the two bolts B, that fix the element to the main frame.
• Try to align the element by moving it side wards, till it ligns up with the adjacent ones.
• Start to tighten all bolts/nuts.

@The element may be pushed out of line due to overload to the machine.

@When a crank is replaced, always realign the element, because if no additional tension is created in the total element assembly.

@Any pre-tension in the element assembly will shorten the bearing life and may damage other parts as well.

15.0 OPTIONS, CORE COLLECTOR

An easy mountable core collector is available for the 7416. The part number is 9200080. ASSEMBLING INSTUCTIONS (see Fig 10):

• Preparation of the Verti-Drain:
  - Fit eye bolts 24 to the main frame 26.
  - Assemble bushes 15 with the new longer bolts 18 to the rear roller supports.
  @These bushes can stay on the machine all the time.
  @ Use washers A16 to align the bushes to the rear roller scraper support.
• Assembling the core collector itself:
  - Assemble supports 17 with eye bolts 9 and nuts 10/11 to the main collector plate 1.
  - Screw the side panels 2/3 with bolts 7 and Bushes 8 to the main collector plate 1.
  - Assemble the rubber strip 12 with bolts 13, washers 14 and nuts 6 to the plate 1.
  - Assemble all the sheet springs 4, well aligned, to the main plate 1.
  @Choose for the time being the centre hole for bolts 7. This setting can be changed later.
  @The side panels 2/3 should not be tight, but moveable around the bushes 8.

Diagram Description: Figure 10 shows the assembly of the core collector option for the Verti-Drain 7416. It provides a detailed exploded view of the components and their mounting points.

Diagram Labels: Numbers indicate various parts of the core collector assembly, such as bolts, nuts, plates, and supports.

USER INSTRUCTIONS:

• When the core collector and the Verti-Drain are well prepared, the core collector supports 17 can be slide (X) onto the bushes 15. Secure it with R pins 19. The rear roller is of the ground, when the core collector is attached. It the clearance is not enough, do NOT remove the rear roller (since the weight is needed) but turn the roller up by taking on bearing bolt out.
• The rear roller supports at the machine must float. So don't lock them with pin 10 (fig.2.)
• Fit chain 20 with two D- shackles to support 17 and eye bolt 24. Ensure left and right are set at the same length. Allow about 100 mm (4") play, so the core collector can follow the ground perfectly and is lifted when the machine is raised. When the working depth on the machine is adjusted, the chain length needs to be checked.
• The rubber seal strip 12 is the first and major shovel that should hold the cores. The ground clearance should be about the core diameter and can be adjusted by choosing other holes for bolts 7.
• The blade springs 4 act as fine cleaner, because they can individually follow the ground contours. The pressure can be set by tilting the main body plate 1 forwards or backwards (Y). This can be achieved by adjusting the top and bottom eyebolt 9 position to the main plate 1.
• The core collector can collect the core for a certain pass length. The length depends on the amount of cores and the sizes.
• If the area isn't clean, check the gap between the rubber seal strip 12 and the blade spring tension 4. Extra weight on top of the core collector may help as well.

15.1 OPTIONS, TURF HOLD DOWN KIT

A Turf Hold Down Kit can be used when the turf is coming loose. Two kits are available for the 7416. One with fingers lining up with the 12 mm (1/2") holes of the tine holder (part # 211.741.002) and one with finger lining up with the 18 mm (3/4") holes (part #211.741.004).

As a standard the Verti-Drain 7416 already has a pre-mounted main beam the turf hold-down fingers can be mounted on.

The kit consists of a set of turf hold-down fingers for 12 or 18 mm pins and the mounting material consisting of a number of bolts and nuts.

ASSEMBLING THE TURF HOLD DOWN KIT (see fig.11):

• The ordered set comes with plates 4 or 5. Mount the plates with bolt 3 and nut 2 on the main beam 1. Align the plates with the pins through the slotted holes in the plates.
• If the fingers are bent in one direction after a long while, mount them the opposite way.

SOME OTHER NOTES:

• When the tines are not centred to the machine anymore, the tines may hit the side of the slots. Realign the tine holders.
• If the tines hit the front of the hole (during work), check the draw rod length.
• * Never creep under the machine. Have the machine well blocked.

Diagram Description: Figure 11 shows the assembly of the Turf Hold Down Kit. It illustrates how the plates and fingers are attached to the main beam of the Verti-Drain.

Diagram Labels: Numbers indicate various parts of the kit, such as plates, bolts, nuts, and the main beam.

15.2 OPTIONS, TINES

Tines are essential for the correct working of the machine. Several tines are available for this machine, see the spare part pages for a total overview. Generally speaking, tines can be divided into two categories: Solids and Hollows. We advise using genuine tines, since they are fully adapted to the machine.

In fig. 12. several tine combination are given. The tine holders have 3 x 12 mm (1/2") holes and 2 x 18 mm (3/4") holes for adapting tines. The lock bolt A may be tightened till 40 Nm (30 lbs.ft.). If the tines still slip out of the adapter, grind a flat area to the tine.

Diagram Description: Figure 12 shows different tine combinations for the Verti-Drain. It illustrates how solid and hollow tines are mounted in the tine holders.

15.2.1 SOLID TINES

Solid tines will break the hard compaction in the ground. The tine angle setting (see par.6.0) determines the amount of “kick” action in the ground. If the angle is adjusted from 90 degrees up to 65 degrees, the “kick” action increases. With a 90 degrees setting we hardly create any tine motion in the ground, with 75 degrees we have the maximum tine action in the ground.

When tines are new, they may disrupt the turf, especially when the root system is weak. Clean the tines first by hand or use the machine for 10 minutes at another rough area.

If the root system is weak, don't try to break the soil much deeper than the root system. Adjust the working depth till the penetration is about 75 mm (3") more than the root system depth. This allows the roots to grow deeper. Next time penetrate deeper. Using this method will safe you from damaging the turf and will establish a healthy root system.

We advise to use the solid tines with the sharp point facing to the front roller. This will create the best tine action in the ground. However with a weak turf, it is worth using the tines with the sharp edge facing the rear roller.

The rear roller may not be locked.

15.2.2 HOLLOW TINES

With hollow tines, the soil can be exchanged. Different sizes are available, see the spare part manual. The side outlet should face to the rear of the machine.

It is important that the tine angle is set at 90 degrees with hollow coring tines. The tine motion in the ground is minimum and we create a nice clean hole. If the tine is still moving in the ground, the hollow tine may break in the end.

If top dressing needs to be applied, use the Verti-Drain first, remove the cores and start spreading sand.

If a lot of dirt is created during hollow coring, reduce your rpm's or irrigate first. The dirt may wear your machine.

When the turf is damaged use the solid tines first to establish a healthy root system first or adjust the working depth.

The rear roller may be lifted and locked with the lock pin, so it doesn't squash the cores. However when the machine is a bit unstable and the rear roller starts to vibrate, it is better to keep the rear roller on the ground.

If the hollow tines block, it means that the ground is (very) compacted and solid need to be used first to break the ground. Irrigation may help as well, as adjusting the working depth.

15.3 OPTIONS, NEEDLE TINES

With the needle tines, we can create many holes that are hardly noticeable.

A special adapter is required to mount 8 needle tine per tine head from the machine, see fig. 13, left. The adapter blocks are bolted against the bottom of the tine holder with two bolts D. The mark (drilled centre points) should face to the centre of the machine.

The adapter can take solid needle tines of hollow needle tines. The 8 tines per adapter block are tightened with a bolt. Since we have two rows, the bolts should be mounted from the front and back, at the longest threaded hole part. The maximum torque on these bolts should be 40 Nm (30 lbs.ft.)

We advise a machine setting of 90 degrees, so we create nice straight holes.

The height setting of the machine needs some adjustment to compensate for the adapter block.

If the needle tines rip the turf, take some tines out.

The complete adapter block (without tine) has the part number 9990211 (6 needed for a full set).

Diagram Description: Figure 13 shows the mounting of needle tines. It illustrates the adapter blocks, bolts, and the positioning of the tines relative to the center of the machine.
