Attaching to the Tractor

WARNING
1. This Power Ditcher is set up for a Category I or II
three point hitch or Category II quick coupler. Careful
attention should be given to mounting the ditcher to
the tractor. The three tractor lift links should be
connected to the ditcher with the connecting pins.
The universal drive shaft should be connected to the
tractor PTO shaft by slipping the shaft forward until
the quick disconnect pin slips into the groove on the
tractor PTO shaft. Periodic cleaning and a few drops
of oil on the splined surfaces and on the quick
disconnect pin will simplify this operation. Be careful,
the universal drive shaft could slip off the tractor PTO
shaft if the quick disconnect pin is not properly
seated.
2. The parking stands should be raised and pinned in
the raised position. The ditcher should be slowly
raised and lowered to check the drive shaft length. At
least 4" of the square shaft should be engaged in the
tubular portion of the universal drive shaft. Check the
drive shaft in the fully retracted position to make sure
it is not binding and will turn freely. Also check to be
sure the drive shaft will not hit the tractor drawbar.
3. The tractor’s top lift link should be extended or
retracted until the chain case is vertical when
lowered to the normal operating position. The
universal drive shaft must have an equal offset in
each joint (See Figure 4-5.) As an example, if the
front joint is offset 6 degrees the rear joint must also
have a 6 degree offset. Should the rear joint be offset
4 degrees or 8 degrees the cutter head will not run at
a constant speed and will vibrate excessively.
Operating the ditcher in this condition will cause drive
shaft, shear bolt and chain failures.
