5. If Dim A is at least 1" (25 mm) longer than Dim B, the PTO shaft does not require trimming. It is recommended the shaft not be used if there is less than 6" (150 mm) of overlap between the two halves of the PTO shaft when the equipment is in the operating position.
6. If Dim B is longer than Dim A, the PTO shaft will require trimming. Use this equation to calculate the correct amount to trim: (B - A) + 1 inch = C (Amount to Trim)
7. Once C has been calculated, trim that amount from BOTH halves of the PTO shaft safety cover first, then trim the same amount from both shafts. This will ensure the safety cover on each end remains a few inches back from the ends of the shafts, otherwise PTO shaft reassembly could be difficult.
8. After trimming both halves of the PTO shaft, use a file to remove any burrs or sharp edges and slide the halves back together, ensuring they telescope in-and-out freely. The PTO shaft is now ready to connect the stump grinÞdrsetr to the tractor for operation.

OPERATION
PRE-START CHECKLIST
1. Prior to operation, ensure all 34 teeth are torqued to 160 ft·lb [215 N·m] using a torque wrench with a 24 mm socket. Refer to the "FLYWHEEL TOOTH TORQUING" section of the operator's manual.
2. With the stump grinder attached to your tractor, take the appropriate measurements to trim the PTO shaft. Refer to the "TRIMMING THE PTO SHAFT" section of the operator's manual for detailed instructions. Note: Failure to do so may result in severe damage to the implement and is not covered under warranty.
3. The stump grinder has multiple bearings fitted with Zerk fittings for greasing. The PTO shaft is fitted with two (2) Zerk fittings, one on each yoke. The PTO shaft and all bearings com e pre-greased and do not require greasing on initial start up. Refer to the"M AINTENANCE" section of the operator's manual for detailed maintenance instructions.
4. Read the "STUMP GRINDING PROCEDURE" section of the operator's manual before operating the stump grinder. It is important to grind stumps correctly to ensure optimal grinding performance and safe operation.
START UP
WARNING To avoid death or serious injury, do not grind stumps containing embedded foreign objects such as nails, wire, metal fragments, etc.
1. Wear heavy-duty work gloves, ANSI-approved goggles behind a full-face shield, steel-toed work boots, and a dust mask.
2. Securely attach the stump grinder to the tractor's 3-point hitch system and install the PTO shaft.

6. Reverse over a tree stump and lower the stump grinder so it will remove 2" (50 mm) per pass. Always ensure the grinder is cutting properly and not jumping around erratically.
7. Once the stump is at ground level, continue to take up to 2" (50 mm) deep passes until the stump and roots are 4-6" (100-150 mm) below grade. Keep a watch out for foreign objects below the soil like rocks or buried metal. These can damage or break the teeth resulting in poor grinding performance.
8. During use, it is important to never let the stump grinder sway beyond an angle that will allow the PTO shaft to separate. Do not operate the stump grinder with less than 6" (150 mm) of overlap between the two halves of the PTO shaft. If the stump grinder begins to sway, it means either the tractor is advancing faster than the grinder can remove material or that too much material is being removed per pass. If this is observed, immediately stop moving forward and position the tractor and stump grinder in a manner so that it is in the vertical position. Take a slower pass and/or shallower cut if necessary.
