Detailed Specifications of the RoadMaster®:
STANDARD SPECIFICATIONS:
longer engine life.
Tractor: Industrial mowing tractor, slope cutting to 31
degrees riding 88" cut, rear discharge, out-front rotary,
self propelled by a closed loop hydrostatic drive
system, powering 38 x 18.00-20 drive wheels, steering
wheel with hydraulic assist. 80 HP diesel engine.
Operator seated at the rear extremity of the machine
for safety. ¼" plate steel mowing deck supports the
chassis from the front while pivoting side to side to
follow the contour of the ground. 4" through 8" cutter
height adjustment. Standard with 4 point ROPS and
retractable seat belt.
OTHER STANDARD DESIGN FEATURES:
Operator Safety Switch -- Must be attached to the
operator so that when pulled it functions as an
emergency brake and safety shutdown. It cuts off and
dynamically brakes the machine should the operator
separate from the machine for any reason.
Propulsion – Hand lever activated, closed loop
hydraulic system including direct drive hydraulic pump
with dual speed wheel motors coupled to planetary
hubs, powering the forward and reverse rotation of the
wheels. The system is supplied with hydraulic oil from
a 58 gallon reservoir through a 10 micron filter system
with a total system capacity of 62 gallons.
Steering – A steering wheel directs the two 6.00-16, 6
ply wheels mounted on the front of the cutter deck.
Has hydraulic power assist. Additional steering assist
brakes are actuated by foot pedals located right and
left on the floor forward of the operator. The steering
assist brakes may be individually activated to hold the
machine on slopes for periods of short duration or for
quick turns. For emergency braking, the pedals can be
applied together.
Operational Braking – When the propulsion lever is
returned toward the neutral position, the machine is
hydraulically braked. When in neutral, the machine’s
movement is braked whether or not the engine is
running.
Parking Brakes – The two steering assist pedals may
be latched together then applied simultaneously by
foot as a parking brake. The steering assist pedals
actuate automotive disc type brakes that are located
on the two drive wheel assembles.
Freewheeling Device – Disengages the planetary
gearboxes by reversing the caps located on the
outside face of each gearbox. When towing, use only
a rigid towbar.
Wheels – Drive: 38 x 18.00-20, 8 ply rating tractor
tread for best traction in rough or wet conditions.
Steering: 6.00-16, 6 ply rating.
Controls – For safety and convenience all the
controls are ergonomically located. The steering
wheel, propulsion lever, throttle, engine gauges and
ignition switch are located on the dash panel
immediately in front of the operator with the blade
engagement controls on the right panel. The high/low
drive speed control is located on the left panel, and
parking/steering brake pedals on the floor of the cab.
PERFORMANCE DATA AND CAPACITIES:
Speed – 0 to 11 MPH (Low) / 0 to 24 MPH (High)
Fuel System – Dual tanks, with 28 gallon total
capacity.
Oil System – The RM is designed to use the same
type oil in both the engine and hydraulic systems.
(Chevron Delo 400, 30 wt. or equivalent.)
Cutting Height – Adjustable 4" through 8"
Fuel Consumption -- 3.25 gallons per hour.
Ready to Operate – The mower has been
operationally tested, is shipped fully assembled.
Size and Weight – 6020 lbs., 93" W, 160" L.
OPTIONS:
Rear Towed Cutter – Cutting width: Rotary – 15’
7" (187"). Hydraulic controls in the cab allow the
operator to raise, lower and engage the blades on each
(left & right) deck independently. Towed cutter attaches
or detaches from tractor, without tools, in less than 5
min.
Enclosed Cab – With air conditioner, heater and wind
shield wiper.
Snow Blower – Two stage, 88" hydraulically driven.
Sweeper – 84" Hydraulically driven.
Snow Plow – 102" Hydraulic lift and tilt.
High Lift Blades – For best refined cut and end of
season leaf mulching.
Dual Tires -- For increased traction and flotation in soft
terrain.
Turf Tires – To minimize turf disruption where reduced
traction and slope-ability is acceptable.
DESIGN CONSIDERATIONS-PATENTS:
The RM is specially designed for safety and
performance in medium to rough mowing applications in
flat areas as well as slopes not to exceed 31 degrees.
Engineered features necessary for practical and safe
operation on slopes include extra wide wheel base, a
low center of gravity, tip-up protection, special cockpit
and tilting suspension seat with restraining arms and
retractable seat belt. The front cutting, rear discharge
cutter assembly rigidly supports the chassis from the
front while pivoting to the side to contour with the turf.
The rear discharge cutter significantly reduces the
hazard of thrown objects. The 58 gallon hydraulic
reservoir is the central structural member of the
machine, contributing to its low center of gravity,
eliminates oil foaming and overheating. The engine is
mounted in the center of the machine and is exposed to
assure good cooling and ease of maintenance. The
operator position is located at the rear extremity of the
machine permitting the operator to continuously look
forward in normal operation, and to assure his safety
should he separate himself from the machine for any
reason. Both the cutter assembly and the propulsion
system are designed so that the engine can only be
started when the cutters are disengaged and the
propulsion system is in neutral. This machine is covered
by one or more of the following patents or patents

355; 89109075.5
Cutting Deck Assembly – Extra heavy duty, ¼" thick
plate steel, rear discharge type deck equipped with
three, 3/8" x 4" x 31" hardened alloy steel blades. The
blades are mounted on 1 3/8" diameter, steel mandrel
shafts, each supported by two precision ball bearings
enclosed in a heavy, machined housing.
Tilting Seat – The patented tilting mechanism allows
the operator to tilt up to 30 degrees on slopes. It is
necessary for the operator to maintain his seating
while traversing and turning on steep slopes. The arm
rests not only rest the operator but restrain and hold
the operator in the seat during steep slope operation.
The arm rests are individually pressed down to tilt the
seat.
Engine – 80 HP Cummins industrial, cast iron, watercooled
diesel engine.
Air Filter – A special multi-stage engine air filter. Dust
and dirt are removed centrifugally and deposited in a
dust cup. A replaceable element removes finer
particles. The filter reduces maintenance, assuring
