Specifications
Note: Specifications and design subject to change without notice.
Engine Kubota, three-cylinder, 4-cycle liquid cooled diesel engine. 26 hp @ 3000. The engine is 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 The radiator has tube-and-fin construction with the hydraulic oil cooler in the lower tank. Cooling
system capacity is approximately 6 quarts (5.7 l) of a 50% mixture of permanent, ethylene glycol
anti-freeze and water.
Electrical The 12-volt battery has 630-amp., cold cranking performance at 0° F (– 18° C). The fuse block is
located under the control panel.
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 a 20:9:1 reduction. 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 A 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). The 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) 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 No. 23-9740.
Ground Speed: Speed is infinitely variable from 0 to 9.5 MPH (0 to 15 km/h) forward or reverse.
Tires The two rear tires are 16 x 6.50-8, 4-ply, tubeless ribbed type, on demountable, drop-center
wheels. The two from tires are 23 x 8.50-12, extra traction tread, 4-ply rating, on demountable
wheels. Recommended air pressure for both the front and rear tires is 21 psi (145 kPa).
Brakes The brakes are controlled by three pedals. Two are for steering assist, and are individually
controlled by the driver’s left foot. The third pedal operates both brakes; it is controlled by either
foot. A parking brake latch is provided for the third pedal. Pedals are connected to brakes by a
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 in. from the center of a turn to the closest side of the drive wheel; however,
zero turning radius occurs when individual wheel brakes are used. Steering wheel adjustable fore
and aft for operator comfort.
Main Frame The frame is welded 11-gauge steel, reinforced with square and rectangular tubing.
