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.
(Bad Boy Hydrostatic oil is recommended)
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.Install
new filters and replace the 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.
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.
