General Specifications
Engine
Kubota, three cylinder, 4 cycle liquid cooled diesel engine. 26 hp @ 3000. Engine
governed to 3200–3250 rpm high idle, no load.
Air Cleaner Heavy duty, remote mounted
Muffler
Volume equal to approximately five times engine displacement for excellent
silencing.
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.
Electrical
12 volt battery has 630 amp., cold cranking performance at 0
°
F (–18
°
C). Fuse
block located under the control panel. Starter relay interlock circuit for maximum
current hold–in of starter solenoid in low voltage conditions
Fuel System
Fuel tank capacity is approximately 6-1/2 gal. (25 l). 12 volt, electric fuel pump .
Fuel filter/water separator with replaceable cartridge is mounted on frame.
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.
Rear Axle
(Models 30627 & 30631)
The rear axle is mechanically driven from the front axle by a universal shaft. Axle
has a bidirectional – overrunning clutch in rear driveshaft. When lubricating rear
axle, use SAE 80W-90 gear lube, API GL-5. Lubricant capacity is approximately
2.2 qt. (2.1 L).
Transmission
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
0.913 cubic inch (15 cm
3
) 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.
Ground Speed Speed is infinitely variable from 0 to 9.5 MPH (0 to 15 km/h) forward or reverse.
Tires
Two rear tires are 18 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
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.
Steering
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.
Main Frame
Frame is welded, formed 11 ga. steel, reinforced with square and rectangular
tubing.
