SERVICE SECTION
SECTION 1: HYDROSTATIC SYSTEM
The hydro overflow tanks on a ZT are located on the
sides of the rear cover. Notice the “full cold” line at the
bottom of the tank. Use only 20w50 motor oil in this tank.
Conventional or synthetic oil may be used.
When servicing a mower with a sealed transaxle unit,
start by removing the filter skid plate on the bottom of
each unit. The skid is held on by three 10mm bolts. Next,
remove the filter. The filter also serves as the oil drain.
Each transaxle holds about 2 quarts of hydro oil.Re-install
new filters and skid plates. Use only hydro-gear filters.
Use of any other type of filter will result in damage to the
hydro system and void the warranty. Transaxle service
recommended within the first 50 hours of usage and
every 250 hours thereafter or once a year.
The check plug is located at the top center of the inside
case of each transaxle. The transaxle can be filled with oil
by removing these check plugs from both transaxles and
pouring the oil in the hydro overflow tank, located behind
the seat. Oil will begin to run out of the check plug holes
when the transaxles are full. Use only 20w50 motor oil in
the hydro system.
