Transporting
!
WARNING
1.
Make sure driveline does not contact tractor or cutter 
when raising cutter to transport position.
2.
Reduce tractor ground speed when turning and leave 
enough clearance so cutter does not contact 
obstacles such as buildings, trees, or fences.
3.
Limit transport speed to 20 mph. Transport only with 
a farm tractor of sufficient size and horsepower. 
4.
When traveling on roadways, transport in such a way 
that faster moving vehicles may pass you safely.
5.
Shift tractor to a lower gear when traveling over rough 
or hilly terrain.
Blade Engagement & Disengagement
Cutter blades can lock-up against each other during 
start-up and shut-down especially if the tractor’s PTO 
engagement is “INSTANT ON” and “INSTANT OFF”
Following Blade Engagement and Blade Disengagement 
instructions below will help eliminate blade lock up.
Blade Engagement
1.
Increase throttle to a speed just enough to get the 
cutter started without stalling tractor while slowly 
engaging PTO drivelines. Use tractor’s PTO soft start 
option if available.
2.
Ensure that all power shafts are rotating and that the 
cutter is not vibrating excessively after ramping up to 
PTO speed for at least 3 seconds. If excessive 
vibration continues after 3 seconds at full PTO 
speed, disengage PTO immediately, shut down 
tractor, and remove switch key.
3.
Check blades for a lock-up situation. Block cutter 
deck up before working under the unit. Unlock 
blades, remove support blocks, and repeat “Blade 
Engagement”
 instructions. 
Blade Disengagement
1.
Slowly decrease throttle speed until engine idle 
speed is reached and then disengage PTO.
2.
Engage tractor park brake, shut tractor engine off 
and remove switch key. Stay on tractor until blades 
have come to a complete stop.
IMPORTANT: Always disengage tractor PTO before 
raising cutter to transport position.
Field Operation
!
WARNING
1.
Thoroughly inspect area to be cut for debris and 
unforeseen objects. Mark any potential hazards.
2.
Follow “Blade Engagement” instructions on this 
page to start cutter blades turning.
3.
Optimum ground speed depends on density of 
material being cut, horsepower rating of tractor, and 
terrain. Always operate tractor at cutter’s full rated 
PTO speed in a gear range that allows the cutter to 
make a smooth cut without lugging tractor down, 
usually between 2 to 5 mph.
4.
Stop traveling and disengage PTO after the first 50 
feet of cutting. Check cutter levelness and cutting 
height to make certain it is adjusted properly. 
5.
Do not engage PTO with 3-point cutter fully raised.
6.
Periodically disengage PTO, shut down tractor, 
remove key, and check for foreign objects wrapped 
around the blade spindle. Block cutter deck up before 
removing objects. 
7.
Frequently inspect cutter for loose bolts and nuts. 
Tighten all loose bolts and nuts as indicated in the 
“Torque Values Chart” on page 32.
8.
NOTE:  Do not cut in wet conditions. Wet material 
will build up on the deck underside creating poor 
discharge, high wear, and additional horsepower.
Periodically disengage PTO, turn off tractor, remove 
key & check for objects wrapped around blade 
spindle. Block deck up before removing objects.
Frequently inspect cutter for loose bolts and nuts. 
Tighten all loose hardware as indicated in the 
“Torque Values Chart” on page 32.
NOTE:  Your cutter is equipped with free swinging 
cutting blades to reduce shock loads when striking 
obstacles. However, it is best to avoid striking 
obstacles to extend cutter and blade life.
