ACCESS TO PARTS
Flip-top bucket seat and hinged hood provide full, instant access for
lubrication and adjustment of brake pulleys, belts and control linkage.
The "725" engine is mounted to blow engine heat forward, away
from the operator. Wide seat is amply padded with foam rubber and rises
high in back to give good support and adds to driver comfort
Power is delivered efficiently to all power take off points and wheels.
The snow blower is driven from the main p. t. o. at the front of the
engine. Power for the rotary mower and all pull-behind attachments is
taken from the spiral bevel gear box, connected directly to the flywheel
end of the engine by a shaft and flexible couplings

STARTER AND GENERATOR AVAILABLE
Optional at slight extra cost for tractors not initially equipped. This
heavy-duty electric starter and generator give fast. effortless starts at
the touch of a button. The unit is equipped with key ignition for added
safety and convenience.
SPEEDS FORWARD AND REVERSE
The "725" has a top speed of 6 mph, second speed of 33/4 mph and
first speed of 2 mph. In addition, a special 10" pulley for
heavy-duty tilling allows the tractor to move at approximately 1 mph. The
oil-lubricated transmission features antifriction ball and roller bearings
on hardened shafts for smooth operation and long life.
SPUR-GEAR DIFFERENTIAL FOR CONTROLLED TRACTION
A special friction mechanism in the "725" differential always
provides driving torque to both wheels in drive at all times, yet retains
true differential action. The controlled traction feature provides solid
footing even when one wheel is on a slippery surface.
A specially designed lever is standard equipment on the "725"
for lifting front or rear-mounted implements. The high leverage ratio
means that little physical effort is required to raise the heavy
attachments. For further ease in handling, counterbalances are available
for both front and rear implements.
