Tracking
If the mower is not tracking straight, check the air
pressure in both rear tires. Recommended air pressure
is 15 psi (1 bar). Tracking must be checked on a flat
and level concrete or blacktop surface.
The tracking knob is located in front of the left control
lever. Rotating this knob allows fine tuning adjustments
so that the machine tracks straight with the drive
levers in the full forward position.
Rotate the knob clockwise (as viewed from the
operating position) to increase the speed or
counterclockwise to decrease the speed on the left
control lever. Example: If control levers are full forward
and the unit turns to the right, turn the tracking knob
counterclockwise to decrease the speed on the left
control lever.
If unit still does not track straight, contact a Yazoo/
Kees dealer for adjustment.
Bypass Linkages
When pushing or pulling the mower, be sure to open
the release valves on the both hydraulic pumps.
Always turn off engine before engaging or disengaging
the hydro release. Never attempt to adjust the bypass
linkages with the engine running.
The hydro release valves are located below the seat,
on the front side of the hydro pumps.
1. Raise the deck into highest cutting position.
2. Lift the seat frame assembly to access the
release valves.
3. Use a 5 /
8
" wrench to rotate bolt counter-
clockwise two full turns to disengage pump.
4. Repeat the procedure for the opposite pump.
5. To engage, rotate each pump bolt clockwise
until the bolt is snug. Do not overtighten the
release valve or damage to the hydro pump
could occur.
