The tractor must be equipped with a 540 RPM PTO
to match the grinder mixer as described in the
previous section. Make sure the grinder mixer and
the tractor are equipped and set for the proper
RPM.
CAUTION: NEVER OPERATE A 540 RPM
GRINDER MIXER WITH A 1000 RPM
TRACTOR PTO.

ITCH
The hitch for the grinder mixer is designed to attach
to any SAE
– ASAE standardized tractor drawbar.
Adjust the drawbar so it is 13 to 17 inches above
the ground (See Figure 12). Extend or shorten the
tractor drawbar so the horizontal distance from the
end of the tractor PTO shaft to the center of the
hitch pin hole is 14 inches for 540 RPM.
Lock the drawbar in its crossbar, parallel with the
centerline of the PTO. Place locking pins on each
side of the drawbar. If the tractor has an offset
drawbar, the offset should be down for PTO work.
IMPORTANT: An improperly located hitch point
may cause damage to the universal joints (U-
Joints) of the PTO driveline.

Carefully back the tractor up to the hitch. Use the
crank of the jack to raise or lower the grinder mixer
hitch into position to engage the tractor drawbar.
Fasten the grinder mixer hitch to the drawbar with a
hitch pin that cannot bounce out. Raise the jack and
lock into the transport position (See Figure 13).
Attach the safety chain from the grinder mixer to the
tractor (See Figure 14).
