Tractor Requirements
The Parallel Arm Cutter, by design, must be used only
on tractors that are capable of controlling the cutter
under all operating conditions. When the arms are fully
extended, a right-hand torque load on the tractor is
present which will try to tip the tractor over! The tractor
MUST have a minimum weight of 7000 lbs. A 3-Point
Category II or Category III hitch with hydraulic lift
control is required.
As shown in Figure 2-1, the rear wheel base must be
not less than 74" wide as measured from the outside of
each tire. If the right-hand tractor tire is more than 47"
from the center of the tractor, it may interfere with the
hydraulic motor on the deck when it is in the transport
position. If the tractor is equipped with dual wheels, the
right-hand dual may have to be removed.
A single, tractor duplex hydraulic outlet is required if
the cutter is equipped with the optional Electric
Cylinder Control. Three duplex hydraulic outlets will be
needed for parallel arm and deck control if the cutter is
NOT equipped with the optional Electric Cylinder
Control.
An additional tractor, duplex hydraulic outlet is required
if the cutter is equipped with the optional hydraulic
breakaway cylinder.
A tractor Power Take-Off (PTO) is required for pump/
motor operation. This cutter is available with either 540
rpm or 1000 rpm rated PTO speed increasers. For best
fuel economy, it is recommended that the 540 rpm unit
be used on 1000 rpm tractors. However, PTO output
RPM must be carefully controlled (by engine RPM)
such that the PTO speed does not exceed 540 RPM.
The actual horsepower required for pump/motor
operation is approximately 30 HP.
If the tractor weight is less than 8500 lbs, auxiliary
counterbalance weights will be required. These
weights can be added to the weight bracket of the
hydraulic reservoir or (preferably) to the left-hand
tractor wheel.
The reservoir weight bracket is designed to be used
with conventional John Deere type suitcase weights -
each weight being 100 lbs. A total of 8 weights can be
added to the bracket.
The tractor MUST be equipped with operator protective
equipment in the form of shielding from thrown objects
and Roll Over Protective Structure (ROPS) as shown in
Figure 2-1.
A universal operator protective shield is available from
Great Plains Mfg. Refer to page 16 for more
information and installation.
It is also recommended that protective shielding or
screen be added to the right hand side of the tractor
engine cowling and radiator. This will help protect the
tractor finish and radiator against thrown objects.
The lower 3-Point links of the 3-Point hitch must be
stabilized to prevent side-to-side movement. Most
tractors have sway blocks or adjustable chains for this
purpose.
