HARVEST TEC 655G 85 Gallon Sprayer for Gehl Forage Harvester


Installation Instructions


Mounting the Tank
Begin by bolting the frame legs to forage harvester’s tongue using the 5/8” U-bolts and nuts. The legs with the pump should be attached toward the back and the legs without the pump towards the front. The plates between the legs should be pointing outward on both the front and back legs, which would position the pump towards the back of the forage harvester. Check for wheel clearance and other obstructions. Place the saddle between the legs and attach using the 3/8” bolts, locks, and flats provided. Place the tank in the saddle with the end fitting on the same end as the pump. Use the 5/16” x 4” bolts and strap provided to bolt the tank to the saddle. Thread the filter assembly into the tank fitting. Connect the valve and hose barb to the filter and run the enclosed ½” hose from the valve hose barb to the inlet of the pump.


Installation of Wiring Harnesses

Connect the pump wiring harness to applicator switch assembly wiring harness. In the tractor, plug Connector A (see diagram below) directly to the chopper controls if you have a 1085 or 1285 chopper. The chopper control box will supply power and will put the applicator on pause when running in AUTO mode when hooked to Connector A. For all other model choppers, plug the battery hook-up harness (006-4723G) included with the applicator into Connector A and to the battery. The applicator will not be able to run in AUTO mode with choppers other than the 1085 or 1285.

Installation of the Blower Band and Nozzle Assembly
When the applicator is going to be used as a blower band lubricator, it will be installed in the blower housing of the forage harvester on the side facing forward or backwards. The nozzle assembly must be located in the area of the blower before the feed intake and after the feed discharge. On the 1085 & 1285 models, there is an inspection door that the unit can be bolted to.HARVEST-TEC-655G-85-Gallon-Sprayer-for-Gehl-Forage-Harvester-fig-4

Recommended Tip for Water Lubrication at 40 PSI



Clean the tip strainer and main strainer often. Some inoculants products leave a residue after use. This residue may affect pumping performance, if you have a product residue, flush the system with clean water after each use.
