DRIVELINE ATTACHMENT TO TRACTOR
1. Grab and pull collar on end of attaching yoke toward cutter.
2. Slide yoke (with collar depressed) onto PTO shaft.
3. Move yoke back and forth until locking collar clicks forward and locks the yoke in place.
WARNING! When attaching PTO yoke to tractor PTO shaft, it is important that spring activated locking
collar slides freely and is seated in groove on PTO shaft.
WARNING! Be sure PTO shielding and all other shielding is installed and is in good condition.
CUTTING HEIGHT ADJUSTMENT
WARNING! Avoid personal injury! Be sure tractor engine is off, key is removed, and ALLOW BLADES TO
STOP TURNING before dismounting to make adjustments.
Important: Avoid very low cutting heights. Striking the ground with blades gives the most damaging shock
loads a cutter can encounter and will cause damage to cutter and drive.
1. Using the tractor, raise the mower off the ground and support under it with secure blocking so not to let the
mower drift down during maintenance.
2. Holding wheel and yoke assembly up, remove quick-lock pin from top of gauge wheel spindle. Position full
length spacers and half spacer as required. All spacers on top of spindle tube allows for approximately 1" cutting
height. Adjustments range form 1" to a maximum of 4-1/2" in 1/2" increments.
STARTING & STOPPING CUTTER
Power for operating cutter is supplied from tractor PTO. Refer to your tractor manual instructions for engaging
and disengaging the PTO. Always engage the PTO at low engine rpm. Always operate at recommended PTO
speed of 540 RPM. Learn how to stop tractor and cutter quickly in case of an emergency.
IMPORTANT: Stop cutter and tractor immediately upon striking an obstruction. Inspect the cutter and repair
any damage before resuming operation. Do not disengage PTO when engine is a full PTO RPM. Always
idle engine before disengaging PTO.
WARNING! Avoid personal injury. When attempting to stop a tractor which does not have live PTO, the
momentum created by the blade carrier of a rotary cutter can cause the tractor to be pushed
forward. DO NOT operate this cutter unless tractor has live or independent PTO.
To commence operation, reduce engine speed and engage the tractor PTO. Before starting to cut, gradually
increase engine speed to develop full PTO speed.
