3.4 EQUIPMENT MATCHING
To ensure the safe and reliable operation of the Reddi-
Arm, it is necessary to use a tractor with appropriate
specifications.
Be certain that these requirements are met:
1.
A full cab tractor or one with ROPS (Rollover
Protective system).
2.
A working seat belt.
3.
Horsepower:
The Reddi-Arm needs both power and mass to pull
and stabilize the unit in all operating conditions. A
minimum of 140 PTO HP tractor is recommended.
Different conditions or mowers may require different
horsepower or tractor mass.
4. Hydraulic System:
The tractor’s hydraulic system must be capable of a
minimum of 10 gpm (38 lpm) at 1800 psi (12,420
kPa) but not to exceed 2800 psi (19,320 lpm).
Depending on the option selected the Reddi-Arm
requires 3-4 hydraulic circuits to control the axle
position, mower height, and mower wings. Switches
that control the selector valves are mounted in the
cab for access by the operator.
5. 3-Point Hitch:
The Reddi-Arm is designed with a frame that
connects to the lower arms of a tractor’s 3-point
hitch. Either Cat II or Cat III works with the machine.
Always secure the mounting pins with retainers.
6. PTO:
A tractor with a 1000 RPM PTO is required. Either 21
spline, 1
3/8
inch or 20 spline, 1
3/4
inch yokes are
available.
