Skid Steer Thrifty® Cutter
This cutter was designed for a skid steer loader. The loader plate has a floating link to
allow the cutter to float freely up and down at the front while in use. The hydraulics
has a check-valve in the line that will act like an overrunning clutch when the cutter is
stopped. This avoids the tremendous pressure surge when the valve is closed, allows
the blade to be turned by hand during servicing and will not run the cutter in reverse
rotation.
Operating the Thrifty® Cutter
With the cutter secured to the loader and you are at the site you want to cut.
Ensure that NO bystanders or workers are in the vicinity that you want to cut.
Do not run cutter in any other position then flat on the ground!
Be sure to stop the cutter whenever you raise it off the ground!

Operating the Thrifty® Cutter
This cutter is mounted in front of the loader and is pushed rather then dragged. The
loader is also capable to put down pressure on the cutter, (this is not desirable).
With the cutter tilted up slightly at the front, lower the cutter until the sides almost touch
the ground.
o Tilt the cutter down until the front comes in contact with the ground.
o Tilt it a little further to allow the cutter to float over uneven terrain.
o Slowly start the cutter and bring it up to Full speed. (It is the speed of the blades
that do the cutting).
o Lift the cutter up before turning
o Stop the cutter any time it is not in contact with the ground.
o Slow down if the cutter speed decreases.
o After the job is completed Stop the cutter blade.
When driving with the cutter attached to the loader. Lift the cutter up for ground
clearance only.
The cutter extends out the front and will tend to swing in a larger arc when turning and
may cause the loader to be unstable.

These torques are for a reference only. Not all these sizes and grades are necessarily used
in this machine. Bolts that are used as a pivot or hinge have to be used with a locknut,
therefore only tighten enough to secure the bolt and still allowing the part to rotate freely.
