OPERATION AND MAINTENANCE
Power Ditcher Operation and
Adjustments
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 three (3) point 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. 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.

WARNING
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 three point
linkage or a Category II or III quick coupler (See
Figure 4-2.) A Category II three point 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 three point 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.
