Remove bolts that secure linkage to upper control 
handles and lower control arms. The shock 
absorbers should remain connected to linkage.
See Figure 12.
Figure 12 
Insert quarter inch by seven inch pin or equivalent 
through the top and bottom alignment holes of the 
control arms to secure arms at positive neutral. 
With the shock absorber still bolted to linkage, 
loosen the jam nuts at both ends of the linkage so 
the alignaball adjustment can be made.
Adjust the alignaball until retaining bolts slips 
through alignaball and hole in arm with little effort.
Re-install bolts, washers, and nuts in all four ends 
of linkage. Tighten jam nuts against alignaball ends 
to keep ends from turning.
Lift rear wheels off ground using floor jack or other 
suitable lifting device.
With quarter inch by seven inch pins still installed in 
the top and bottom linkage arms, loosen the jam 
nuts at both the front and rear ends of linkage that 
runs from bottom linkage arms to hydrostatic 
pumps. See Figure 13.
Figure 13
Set parking brake and start the engine (set throttle 
at full speed). Make sure that the PTO is OFF.
Rotate rods (lengthen or shorten) to bring each 
hydrostat to neutral.
NOTE:  The control linkage going to the hydrostatic
pump has left-handed threads at the pump and right-
handed threads at the tower.
Tighten the jam nuts earlier loosened and 
reassembled the safety switches.
Remove quarter inch by seven inch pins from top 
and bottom holes.
Reassemble body panels and drive handle 
assembly.
Make sure that all hardware is tightened.
SECTION 6:  MAINTAINING YOUR Z-SERIES
WARNING: Before performing any
maintenance or repairs, stop the engine,
disconnect the spark plug wire, and
ground against the engine to prevent
unintended starting.
Lubrication
Engine
Lubricate the engine with motor oil as instructed in the 
separate engine manual packed with your unit.
Control  Tower
There are two grease fittings that are located on the 
right side of tower. Lubricate both with a grease gun at 
least once a season. The control tower cover must be 
removed to lubricate. See Figure 14.
Caster Assembly / Wheels
There are three grease fittings, one on each wheel 
spindle and one in middle of caster assembly. The 
caster wheels have one grease fitting on each wheel. 
Lubricate these with a grease gun at least once a 
season. See Figure 14.
Deck Lift Pivot / Lift Handle
The deck lift pivot assembly has grease fittings on each 
end and the lift handle has a grease fitting on its lower 
side. Lubricate with a grease gun at least once a 
season. See Figure 14.
Mower Deck
The mower deck may have grease fittings located on 
the idler assembly or the spindle assemblies.
