4.
Secure the Hitch Plate using the two 3/4" x 4-1/4" pins with lynch pins.
5.
Tighten the front bolts and remove the 3/4" spacer bolts.
The 3/4" Spacer Bolts must be removed before use. Failing to do so will transfer force into
the front of the tractor and could cause catastrophic failure, injury or death.
Installing the Rear Tractor Drive Shaft
Separate the two drive shaft halves and apply multipurpose grease to all sides of the sliding members. Ensure
that drive shaft yokes, and rear gearbox input shafts are dirt free. Apply grease to the rear gearbox input shaft.
The implement yoke on this drive shaft uses a tapered pin to lock the yoke to the gearbox input shaft. Slide the
yoke onto rear gearbox input shaft, align the tapered pin to the groove on the gearbox shaft and tighten the nut
on the tapered pin.
IMPORTANT: The tapered pin must align with the groove in the gearbox shaft in order to get a secure
connection.
Connect the quick disconnect yoke to the tractor PTO shaft. The driveline yoke and tractor PTO shaft must be
dirt free and greased for attachment. The quick disconnect yoke will either use a collar or push pin to release
the yoke detents. To connect the quick disconnect yoke to the tractor PTO shaft, pull back on the collar or
depress the push pin and align the grooves and splines of the yoke with those of the PTO shaft. Push the drive
shaft yoke onto the PTO shaft, release the locking collar or push pin, and position the yoke so that the locking
balls are seated in the PTO shaft's locking groove. Push and pull the drive shaft several times to check that the
yoke is securely locked onto the PTO shaft.
The rear tractor drive shaft remains at a fixed length during operation. The installed length of the tractor drive
shaft should be between 29" and 33" as measured between the cross and bearing kits. Measurements outside
of these ranges may result in damage to the implement or tractor.
When attaching the quick disconnect yoke to the tractor PTO shaft, it is important that the
spring activated locking collar slides freely and the locking balls are seated securely in the
groove of the PTO shaft. A drive shaft not attached correctly to the tractor PTO shaft could
slip off and result in personal injury and damage to the implement.
