SPECIFICATIONS
Engine: 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
±
100 rpm. 79 cu. in. (1300 cc) 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.
Air Cleaner: Heavy duty, remote mounted.
Cooling System: 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. Radiator is equipped with a 1 psi
(90 kPa) pressure cap and engine has a 195
F
thermostat.
Electrical: 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. (24 L)
of lead–free gasoline.
Front Axle: 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.
Transmission: Sauer–Danfoss in–line hydrostatic
transmission is mounted directly to the front axle and
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 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) of SAE
10W–30 or 10W–40 engine oil. The 25 micron hydraulic
oil filter is a screw on replaceable type. For replacement
filters, order Toro part number 23–9740.
Ground Speed: Speed is infinitely variable from 0 to
9.5 mph (0 to 15 km/hr) forward or reverse @ 3200
engine rpm.
Tires: Two rear tires are 16 x 6.50-8, 4-ply, rating rib, on
demountable, drop center wheels. The two front 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: Brakes controlled by 3 pedals. Two are for
steering assist. Each are individually controlled by left
foot. Third pedal operates both brakes and is controlled
by either foot. Parking brake latch provided for third
pedal. Pedals are connected to brakes by
multi–stranded cable and conduit.
Steering: The 15 inch (38 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” 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.
Main Frame: Frame is welded, formed 11 ga. steel,
reinforced with square and rectangular tubing.
Instrument Panel and Controls: Warning light cluster
for battery, oil pressure, engine temperature and glow
plugs. 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.
PTO Drive: Shaft is driven by a tight–slack double “A”
section, torque team V–belt directly from output shaft of
engine. Shaft is clutched by pivoting the shaft support
with a spring loaded, over center, hand operated lever.
PTO speed—1810 rpm @ 3200 rpm engine speed.
Connection to implement is with high quality, needle
bearing universal joint with slip joint.
Implement Lift: Cutting unit or implement is lifted by
hydraulic cylinder that has 2-1/2 in. (64 mm) bore and
3-1/4 in. (82 mm) stroke.
