EQUIPMENT MATCHING
To insure the safe and reliable operation of the Tiller, it is necessary to use a tractor
with the correct specifications. Use the following list as a guide in selecting a tractor to
use on the machine.
1. Horsepower: Use Table 1 as a guide in selecting the tractor horsepower
appropriate for your width of machine. Use only small Agricultural tractors on this
machine.
Table 1 Horsepower vs. Width
Model Width Horsepower
50H 4.2 feet 40
(1.3m)
60H 5 feet 45
(1.5m)
72H 6 feet 55
(1.8m)
82H 7 feet 65
(2.1m)
ALERT: Do not exceed the recommended horsepower levels. The use
of horsepower will void the warranty.
2. Tractor Weight:
By following the recommendations for the tractor power, the tractor will have
sufficient weight to provide stability for the unit during field operation or when
transporting. It is also recommended that each tractor be equipped with a full
complement of suitcase weights on the front of the tractor. This will provide the
required weight on the front for turning and extra traction if equipped with front
wheel assist.
3. 3 Point Hitch:
The Tiller is equipped with a Category 1, 3-point hitch. Be sure the tractor 3-
point hitch is in the Category 1 configuration. Install the lift arm blocks or shorten
the stop chains to place the arms into the non-sway configuration. Refer to the
tractor manual for details.
4. Load Sensing Hydraulics:
Many newer tractors are equipped with “Load Sensing” hydraulics. It is the
responsibility of the operator to set the tractor hydraulic system to provide “float”
on the 3-point hitch. Refer to Tractor Manual for details. The float feature will
allow the machine to follow the ground contours during operation.
5. PTO Shaft:
The tractor must have a 1 3/8” 6 spline 540 rpm PTO shaft to fit the driveline
shaft supplied with the machine. Do not use shaft adapters or operate at any
other speed. It is not recommended that a tractor with variable speed PTO’s be
used on the Tiller. Operating at speeds faster than 540 rpm will overload the
drivetrain and lead to early failures.
Attach the safety chains supplied with the PTO shaft, allowing sufficient slack for
the driveline during turns and operation. Check booklet attached to the PTO for
instructions.
