WARNING
Make sure mower is turned (OFF) before making adjustments
to pump linkage rods.
1. Disengage blade switch and turn ignition switch off.
2. Position control levers in neutral position as shown.
3. Remove fan mounting hardware and fans (#4) if jam
nuts (#3) are not easily accessible.
4. Loosen jam nuts (#3) at both ends of the linkage rods
by 5 or more full turns (approximately 1/4").
5. Using the flat area (#1) on the linkage rods, rotate
rods to lengthen or shorten them until the levers align
with the neutral parking slots.
6. Tighten jam nuts (#3) at both ends to lock linkage
rods in place.
7. If the transaxle fans were removed, reinstall them
and tighten their hardware to the correct torque.
8. Start mower engine and test control lever alignment
by moving the levers forward and backward before
returning them to neutral position. The pump linkage
rods are properly adjusted if the lower control levers
are aligned with the neutral parking slots when
released.
NOTE: Step 3 is not required but may be done if
transaxle fan blades (#4) interfere with loosening
jam nuts (#3).
