Series 1 Rotary Cutter
8
OPERATING INSTRUCTIONS
1. Connecting to tractor: All cutters are supplied with a standard 1 3/8" 6-spline
yoke on the PTO shaft.
Warning: This cutter is designed to operate only with a 540 rpm PTO. After
connecting cutter to tractor and before doing any cutting, check to see that the
PTO shaft is not touching anywhere on the cutter when raising and lowering or
when cornering.
2.
PTO Shafts: Make sure the length of the PTO shaft is compatible with different
working positions of the cutter. Carefully follow the lubrication chart supplied with
the PTO shaft. When cutting, avoid joint angles over 35º. PTO shafts should be
disengaged when turning sharp corners. Using tape or a bright colored marking
pen, mark on the outer shields the position where the shaft is completely pushed
together and the position where you have a 4" overlap. Watch these marks when
moving the cutter through all possible operating angles to see that the PTO shaft
stays within this range.
PTO shafts with shear pin - Loosen the outer shield on the implement end of the
PTO and push the gearbox shaft through the end yoke. Using snap ring pliers,
put the snap ring on the end of the gearbox shaft. This is what keeps the PTO
shaft on if the shear pin breaks and the cutter should
not be used without it.
Insert a ½” x 3 ½”
Grade 2 bolt with a lock nut to act as shear pin and replace all
shields.
3.
Operating tractor engine: Operate the tractor PTO at 540 rpm when doing
normal cutting. If the forward speed is too high, a lower gear can be used.
4.
Cutting: The cutter should be run with the front end a little low or just level for
normal light cutting. For brush or dense tall weeds, running front end high may
give a better shredding job. On rough ground, the front end will also tend to dig
in less. The cutter can also be used to shred stubble or top vegetables prior
to harvest.
