ASSEMBLY

DRIVELINE ATTACHMENT

Before starting assembly, make certain that all paint, dirt, and grease are removed from gearbox shaft. To ease

assembly apply a light coat of grease to splines and assemble. Do not assemble a driveline without a shield.

Entanglement in rotating shafts can kill. Figure Asm-R-

Remove tapered pin from splined clutch hub on the

end of the driveshaft. Rotate the clutch shield up

over the top of the gearbox to expose the gearbox

input shaft. Slide the slip clutch end of the driveline

onto the gearbox input shaft. Make certain that the

slip clutch is fully on the input shaft splines. Align

the tapered pin hole in the hub with the grove on the

input shaft. Install the tapered pin, washer and

locknut. Torque the nut to 30 ft. lbs.

SLIP CLUTCH ADJUSTMENT AND OPERATIONAL CHECK

1. Remove filler plug on top of gearbox housing and oil level plug on right side of housing. Fill gearbox with

EP80W-90 gear oil until oil just reaches bottom of level plug hole. Allow time for oil to seep through

bearings in lower housing of gearbox and then add oil again to reach level plug hole. Replace filler plug on

top of gearbox with breather plug/dipstick supplied in Operator’s Manual Package.

2. Connect cutter to tractor’s 3-point hitch, attaching top link in holes of A-Frame struts using customer

sliding yoke onto shaft. Release collar and slide driveline yoke back and forth on shaft until an audible click

is heard (Ball Collar has seated in groove on PTO Shaft).

4. Loosen eight nuts retaining clutch springs by 1/3 turn or until spring can be turned with fingers.

Clutch should slip without turning cutter blades.

6. Disengage tractor PTO and turn off tractor ignition.

7. Re-tighten nuts on clutch springs to with 1/64” of original position. Initial spring length shown below.
