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  
pending: (U.S.) 4, 453, 739; 4, 515, 337; 4, 515, 392; 4,

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
