Ransomes CT325 - Throttle Controls

CONTROLS AND INSTRUMENTS
• The hours and portions of hours your tractor
has operated, based on an average engine
speed of 1867 rpm. Engine speeds below 1
867 rpm accumulate engine hours at a slower
rate than clock hours. Engine speeds above 1
867 rpm accumulate engine hours faster than
clock hours. Use the Proof-Meter as a guide
to determine hourly service and maintenance
intervals.
• Use the engine revolutions per minute scale
when operating P.1.0-driven equipment.
P.1.0-driven equipment must be operated at
an engine speed not to exceed that indicated
by the line on the rpm scale (2292 rpm on
mechanical-transmission tractors, 2325 with
hydrostatic transmission). Additional
information on P.T.O. operation can be found
on page 18. Ground speeds are indicated on
a decal attached to the instrument panel
(H.S.T) or to the top of the left fender
(mechanical transmission tractor) with engine
speeds from 1 500 to rated rpm. Additional
ground speed information can be found on
page 56. The decal on hydrostatic
transmission tractors shows ground speed for
both ranges.
TEMPERATURE GAUGE
The engine coolant temperature gauge is shown in
Figure 6. When the needle is in the middle area, the
engine is at its normal operating temperature. The
needle at the “red” end indicates an overheated
engine.
WARNING: When engine is at
operating temperature always relieve
pressure in the cooling system before
removing the radiator cap.
THROTTLE CONTROLS
HAND THROTTLE AND ENGINE STOP
CONTROL
The hand throttle is shown in Figure 8 Push the
throttle forward to increase engine rpm. Pull the
throttle rearward to decrease engine rpm. Turning
the key switch to the “OFF” position stops the
engine.
Figure 8 - Hand Throttle
FOOT THROTTLE
The foot throttle, shown in Figure 9, can be used
separately, or in conjunction with the hand throttle
With the hand throttle control lever set at selected
engine rpm, the foot throttle can be used to increase
engine rpm to its maximum speed Upon release of
the foot throttle, the engine speed will return to the
rpm at which the hand( throttle has been set.
