Allis-Chalmers 400 Series - Transmission Control Types

Operating Controls
3. THROTTLE CONTROL LEVER (Figure 1)
Engine speed is set with the throttle control lever.
Push lever forward to increase engine speed and
. puli it backward to reduce engine speed.
Specific information on suggested setting of engine
speed is given in the operation section of. manual,
4. FRONT PTO CLUTCH SWITCH AND WARNING
LIGHT (Figure 1)
The front power take off clutch is engaged when
clutch switch is pushed forward to "On" and is
disengaged when switch is in rear, "Off" position.
Red warning light near switch is on when clutch is
engaged.
5. AMMETER (Figure 1)
The ammeter indicates the rate at which the battery
is being charged or discharged. Normally it should
show some charge when the engine is first started
then gradually diminish toward the zero mark as
battery charge is replenished. If the ammeter
remains in the discharged position with engine at
full speed, see your Allis-Chalmers dealer for
alternator or regulator adjustment.
6. FUEL GAUGE AND FILLER CAP (Figure 1)
The fuel gauge is built into the filler cap and is
located at the rear of the hood. Turn cap counter¬
clockwise to remove and lift straight up.
CAUTION: NEVER add fuel when engine is
running or is hot. Do not smoke or have
open flames near tractor when fuel is added.
7. CLUTCH AND BRAKE PEDAL (Figure 2)
Depressing clutch pedal first disengages the tractor
drive clutch. As pedal is pushed farther forward
the tractor brake is applied to stop the tractor.
NOTE: DO NOT use clutch pedal as a foot rest.
To do so will cause excessive drive belt wear.
8. PARKING BRAKE LOCK (Figures 3 and 4)
To lock the parking brake pull the parking brake
lever up into a vertical position opposite position
shown in Figure 3. Lever can be more easily
lifted and locked in position if foot brake is fully
depressed first. Brake should be locked whenever
operator leaves the tractor seat.
NOTE: Lock is located on right hand fender on
hydrostatic transmission tractors, (Figure 4).
9. HAND LIFT LEVER (Figure 2)
The hand lift lever is used to raise and lower front
mounted, (»nter mounted and rear mounted
implements,
CONTROLS FOR STANDARD 3 SPEED TRANS¬
MISSION TRACTORS
In addition to the 9 controls used on all model tractors,
standard 3 speed transmission tractors also have the
following:
GEAR SHIFT LEVER (Figure 1}
The gear shift lever is used to select which of the 3
forward or the reverse gears is selected. The approximate
ground speeds at 3600 RPM full rated engine speed are:
First
1.57 M.P.H.
Second
3.59 M.P.H.
Third
5.90 M.P.H.
Reverse
3.13 M.P.H.
The gear shift pattern is shown on the tractor control
panel (Figure 1). To shift transmission gears the tractor
movement must be stopped and the clutch brake pedal
must be fully depressed. The gear shift lever must be
in the center of the neutral position for engine starter
to operate.
CONTROLS FOR SHUTTLE CLUTCH TRANSMIS¬
SION TRACTORS
In addition to the 9 controls used on all model tractors,
shuttle clutch tractors also have the following:
1. GEAR SHIFT LEVER (Figure2}
The gear shift lever is used to select which of the
four transmission speeds will be used. Using the
shuttle drive unit the tractor will move forward or
reverse in any of the gears. The approximate
ground speed in miles per hour both forward and
reverse are as follows with full engine speed of
3600 RPM.
Gear
Maximum Ground Speed
First
.96 M.P.H.
Second
2.3 M.P.H.
Third
3.7 M.P.H.
Fourth
5.1 M.P.H.
The gear shift pattern is shown on the tractor
control panel. To shift transmission gears the
tractor movement must be stopped and either the
shuttle drive control lever must be in neutral or
the clutch brake pedal must be fully depressed.
The gear shift lever must be in the center of the
neutral position for the engine starter to operate.
2. SHUTTLE DRIVE CONTROL LEVER (Figure 2)
This lever is used to cause the tractor to move
forward, to move in reverse or to stop. With the
transmission in gear and engine running, pushing
