SERVICE SECTION
SECTION 1: HYDROSTATIC SYSTEM
Pictured to the right are several key components of the
machine: gas tank (center), hydro reservoir tanks (left and
right of the gas tank), carbon canister (top), and battery
(behind gas tank). This compartment is accessed by a rear
door that is secured by a latch to the left.
Never fill the hydro reservoir tanks past the “full cold” line
on the side of each tank. Use only 20W-50 motor oil in
these tanks (Bad Boy Hydrostatic oil is recommended).
When servicing a mower with a sealed transaxle unit, as
this machine is equipped with, 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.
Reinstall 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 20w-50 motor oil in the
hydro system.
Once the system is filled with oil, lift rear of mower until
rear tires are off the ground. Start engine, release parking
brake, stay clear of moving rear tires. Next, push the
neutral bypass levers, move the drive arms forward and
backward 4 to 6 times slowly. This relieves any air that
may be trapped in the system. It may be necessary to add
more oil to the hydro overflow tank after 10-15 minutes of
running. These bypass levers also serve as a neutral for
moving the mower without the engine running.
