Adjustments - Textron Ransomes 930325 Manuel De Maintenance

ADJUSTMENTS

NOTE: Make all adjustments with the engine shut off, spark plug wire disconnected and mower
drive disengaged.
TRACTION DRIVE HYDROSTAT ADJUSTMENTS: The following adjustments must be done in order.
STEP 1 - Set Neutral
Neutral is set at the factory. If it should require
adjustment, raise the wheels off the ground by setting
the machine on jackstands or blocks. Disconnect the
traction control rod A and speed control rod R at each
pump end. Disconnect pump arm spring U from bolt
on engine deck. Loosen bolt S securing the neutral
plate eccentric shaft just enough to turn the shaft.
Start the engine and run at low speed. Turn eccentric
shaft T to raise or lower the point at which the
follower bearing is held in the center of the "V" until
the wheels stop turning. Tighten the eccentric shaft
bolt. Increase the throttle setting and check the
adjustment. Readjust if necessary. Shut the engine
off before proceeding to steps 2 and 3.
STEP 2 - Adjust Speed Control Rods
First adjust neutral, as outlined in Step 1. Set speed
control levers to neutral. Adjust swivels on lower
ends of speed control rods R so they just go into the
slots on the neutral plates.
NOTE: If the speed control levers do not have
adequate tracking adjustment, the swivel on one of
the rods needs to be turned 1 turn.
STEP 3 - Adjust Traction Levers
Set neutral and adjust speed control rods as outlined
in Steps 1 and 2. Set traction locks in the neutral
position. Grasp traction rod A and pull down on it to
take out any slack. The pump control arm has some
back and forth play. Adjust the swivel to the center of
the control arm play. Connect the swivel to the
control arm. Reattach pump arm spring U to bolt on
engine deck.
NOTE: More reverse speed may be gained by
adjusting the swivel to the rear of the control arm play.
A minimum of 1/16" play is required so the traction
controls can be put in neutral without the machine
backing up.
