Driveline Installation

If the Rotary Cutter is to be used on more than one tractor, an additional driveline may be required especially if a quick hitch is used.

!CAUTION

NOTE: A driveline that is too long can damage tractor, gearbox and/or driveline. Check driveline with gearbox shaft aligned and level with the tractor's PTO shaft. This arrangement will provide the shortest distance possible between the two shafts.

Refer to Figure 1-6 on page 11:

Do not use a PTO adaptor. A PTO adapter will increase strain on the tractor’s PTO shaft resulting in possible damage to the shaft and driveline.

!CAUTION

Tractor PTO shield and all Rotary Cutter guards must be in place at all times during operation!

1.Obtain the shortest distance possible between tractor PTO shaft and gearbox shaft by starting the tractor and slowly engaging 3-point lift to move the lower arms up or down until the gearbox shaft is aligned and level with the tractor's PTO shaft. Securely block cutter deck in this position.

2.Place tractor gear selector in park, shut tractor engine off, set park brake and remove switch key.

Refer to Refer to Figure 1-5:

!CAUTION

Always engage parking brake, shut off tractor and remove key before dismounting from tractor.

!WARNING

Damaged drivelines can cause serious injury or death.

IMPORTANT: The driveline must be lubricated before putting it into service. Refer to “Lubrication” on page 22.

3.Remove snap ring (#1) from the 3rd link pin shipping location. Remove rubber protective sleeve from gearbox input shaft and install driveline as follows:

SLIP-CLUTCH DRIVELINE:

a.Discard snap ring (#1).

b.Slide slip-clutch driveline (#5) onto the gearbox input shaft.

c.Align holes in driveline with hole in gearbox shaft and insert 1/2” x 3 1/2” long GR8 bolt (#2). Secure with 1/2” nut (#3) and 1/2” jam nut (#4).

d.Push and pull driveline to be sure it is securely fastened to the gearbox shaft.

IMPORTANT: Some tractors are equipped with multispeed PTO ranges. Be certain your tractor ‘s PTO is set for 540 rpm.

IMPORTANT: Avoid premature driveline breakdown. A driveline that is operating must not exceed an angle of 25 degrees up or down while operating the 3-point lift. See Figure 1-4 below.

Driveline Minimum Length

IMPORTANT: Always check driveline minimum length during initial setup, when connecting to a different tractor and when alternating between using a quick hitch and a standard 3-point hitch. More than one driveline may be required to fit all applications.

SHEAR-BOLT DRIVELINE:

a.Slide shear-bolt driveline onto gearbox shaft.

b.Install snap ring (#1) on gearbox shaft groove. The snap ring is added security in the event the shear-bolt should break.

c.Align holes in driveline with hole in gearbox input shaft and insert 1/2” x 3 1/2” GR2 shearbolt (#2). Secure with 1/2” nut (#3) and 1/2” jam nut (#4).

d.Push and pull the driveline to be sure it is securely fastened to the gearbox shaft.
