Ford, 4 cycle, 4-cylinder, overhead valve, liquid cooled gas engine with centrifugal
water pump. Ford rates engine @ 52 hp (De–rated to 25.5 hp). Mechanically
governed to a maximum speed of 3200
displacement. Distributor less electronic ignition. 3.5 quart (3.25 liter) oil capacity;
replaceable oil filter. Forged connecting rods, cast iron cylinder head and block.
Mechanical fuel pump. Spark arrestor muffler is standard.
Heavy duty, remote mounted
Radiator has tube and fin construction with hydraulic oil cooler in lower tank.
Capacity of cooling system is approximately 6 quarts (5.7 l) of a 50% mixture of
permanent, ethylene glycol anti-freeze and water.
The 12 volt battery has 42 plates and is rated at 45 ampere hours. A 55 amp
alternator with integral regulator is standard.
Fuel tank capacity is approximately 6-1/2 gal. (25 l).
The heavy duty Dana GT 20 axle has reduction of 20:9:1. Axle has automotive type
differential, bevel gear pinion and ring gear with spur gear reduction from
transmission. All axle components are mounted in tapered roller bearings.
The in-line hydrostatic transmission is mounted directly to the front axle and is
driven by flexible drive couplings. Operating pressure is 500 to 3000 psi (3447 to
20685 kPa) and normal charge pressure is 70 to 150 psi (453 to 1034 kPa).
Implement relief valve setting is 700 to 900 psi (4826 to 6205 kPa). Displacement is
3
0.913 cubic inch (15 cm ) per revolution, and transmission is controlled by
foot-actuated pedal. Front axle is the hydraulic fluid reservoir, and its capacity is 5
quarts (4.7 l). The 25 micron hydraulic filter is a screw on replaceable type. For
replacement filters, order Toro Part No. 23-9740.
Speed is infinitely variable from 0 to 9.5 MPH (0 to 15 km/h) forward or reverse.
Two rear tires are 16 x 6.50-8, 4-ply, extra traction tread, on demountable, drop
center wheels. The two from tires are 23 x 8.50-12, extra traction tread, 4-ply rating,
on demountable, drop center wheels. Recommended air pressure for both the front
and rear tires is 21 psi (145 kPa).
Brakes controlled by 3 pedals. Two are for steering assist. Are individually
controlled by left foot. Third pedal operates both brakes; is controlled by either foot.
Parking brake latch provided for third pedal. Pedals are connected to brakes by
multi-stranded cable and conduit.
The 13 inch (33 cm) steering wheel is mounted on a steering valve consisting of a
control valve and metering section which regulates pressure and meters flow to the
steering cylinder. Minimum turning radius is 18 in. from center of turn to closest side
of drive wheel; however, zero turning radius results when individual wheel brakes
are used. Steering wheel adjustable fore and aft for operator comfort.
Frame is welded, formed 11 ga. steel, reinforced with square and rectangular
tubing.
Warning light cluster for battery, oil pressure and engine temperature. Hour–meter,
fuel gauge, ignition switch, coolant temperature switch and gauge to prevent
overheating, choke and throttle control are on instrument panel. Hand operated
PTO lever is located to right of the seat. Foot pedal control for transmission
operation at right of steering column.
