STARTING FOR THE FIRST TIME
1. If everything is in place and the rotary cutter is properly connected to the
tractor, start the tractor and raise the rotary cutter slowly. While watching
the PTO shaft, raise and lower the rotary cutter until you have positioned
the PTO shaft to the shortest telescoping point. This position will check the
PTO shaft to make sure it is not too long. With the shaft positioned at its
shortest length, the two telescoping shafts should lack two inches (2”)
meeting. Now, check the PTO shaft to be sure it is not too short.** Position
the rotary cutter so that the PTO shaft will be at its longest position. At this
position, the two telescoping shafts should engage at least six inches (6”).
Be sure the PTO clears the front of the cutter deck when the cutter is
raised. If it does not clear, readjust the toplink on your tractor to correct
this problem. You may want to set the stop on your hydraulic control lever
so that the cutter will not accidentally be raised too high. Now, engage
the PTO slowly. Let the rotary cutter run slowly for several seconds and
gradually increase throttle to operating speed. Watch carefully for signs of
excessive vibration or unusual noises. If any are noticed, disengage PTO,
shut off tractor immediately, wait for all moving parts to stop completely
and investigate cause. A new gearbox may be noisy at first, but usually a
few hours of use will mesh the gears and create a quieter, smoother
operation.
2. We suggest that you get the feel of your rotary cutter on open familiar
ground. Remember that the centrifugal force of the rotary blades and
carrier can keep pushing your forward even after you have disengaged
your clutch, unless your tractor is equipped with live PTO or an over-
running coupler. Therefore, approach obstacles with caution.
** If it is determined that the PTO shaft is either too long or too short for your
tractor, see your dealer for correct shaft lengths. This is not a frequent problem.
However, the correct shaft lengths should be checked to avoid damage to the
PTO shaft or other components.
