Operation and Adjustments
WARNING
Stop the tractor and disengage the PTO before
making any adjustments. Keep all shields in
place.
1. The Power Ditcher should be lifted from the ground
and the Parking Stands raised and secured with the
Hair Pin Clips. If the tractor is equipped with a float
position on the 3-PT Lift, this should be used. This will
allow the skid to control the depth of cut.
•
To get a deeper ditch, raise the skid by means
of the adjusting bar at the rear of the chain case.
•
To get a more shallow ditch, lower the skid by
means of the adjusting bar.
2. The cutting diameter may be adjusted by moving the
location of the blades on the Cutter Head. Location in
the inside set of holes will give an 18" diameter cut.
Locating the blades in the outside set of holes will give
a 20" diameter cut.
3. Raise and lower the Ditcher slowly to check
engagement of the drive shaft. At least 6" of the
square shaft should be engaged in the tubular portion
of the drive shaft. Also check to be sure the drive shaft
will not hit the tractor drawbar and is not binding when
rotated. Be sure the Safety Shield is secured over the
Shear Flange.
4. The Ditcher should be lowered just above the ground
and the PTO engaged.
IMPORTANT
The PTO should not be engaged with the blades
resting on the ground. This sudden shock could
result in broken shear bolts, chain or drive shaft.
After the Cutter Head has started rotating, set the
engine speed for 540 or 1000 RPM PTO speed. Start
the forward motion of the tractor and lower the Ditcher
into the ground. Forward speed and depth of cut
should be matched to soil conditions.
5. When backing or turning, the Ditcher should be raised
to clear the ground. The Ditcher should never be
raised to maximum height with the PTO engaged.

Attaching to the Tractor
Stop the tractor and disengage the PTO before
making any adjustments. Keep all shields in
place.
1. Both the D5P18A and D10P18A Power Ditchers are
designed for use on a Category II or III 3-PT Linkage
or a Category II or III Quick Coupler.
A Category II 3-PT Linkage attaches to the upper top
hole with 1" diameter top pin. The lower links fit the
1-1/8" diameter portion of the lower hitch pins.
A Category II Quick Coupler is attached to the lower
top hole using the 1" diameter top pin and 1-1/2" O.D.
bushing. The lower hitch attaches to the lower hitch
pins using the 1-7/16" O.D. bushing over the 1-1/8"
diameter portion of the pin with the 2" O.D. spacer
over the 1-7/16" diameter portion of the pin.
A Category III 3-PT Linkage and Quick Coupler
attaches in the upper top hole with the 1" diameter top
pin and the 1-1/4" O.D. bushing. The lower links fit the
1-7/16" diameter portion of the lower hitch pins with
the 1-7/16" O.D. bushing and the 2" O.D. spacer both
located over the 1-1/8" diameter portion of the hitch
pin.
All pins should then be secured with the klik pins.
