CARE AND MAINTENANCE
FORWARD TRAVEL SPEED ADJUSTMENT
1. Drive machine until hydrostats have warmed up.
2. Drive on a smooth, level surface with both levers in top speed position.
3. If one side now drives slightly faster than the other, adjust lever stop washer
P/N 5760 on that side to reduce forward range of control lever. If levers are
now uneven at top speed, loosen control lever mounting nut. Rotate lever
to be even with other side and tighten nut.
