SERVICE SECTION
SECTION 1:
HYDROSTATIC SYSTEM
The hydraulic fluid reservoirs are accessed by raising the
seat forward. Notice the “full cold” line at the bottom of
the tank. Use only 20W-50 motor oil in this tank. (Bad
Boy Hydrostatic oil is recommended)
CHANGING YOUR HYDRAULIC OIL AND FILTER
1.
Remove the caps from the hydraulic fluid
reservoirs and get an oil drain pan. Lifting the
mower from the rear will make access to the
transaxles easier and allow you to purge the air
from the transaxles.
2.
Remove the two 1/4" filter guard screws and filter
guard from the transaxle. Clean any loose debris
from around the perimeter of the filter.
3.
Place the oil drain pan under the oil filter as the
oil filter serves as the drain for the transaxle.
4.
After the oil has drained, wipe the filter base
surface off and apply a film of new oil to the
gasket of the new replacement filter.
5.
Install the new filter by hand, turn 3/4 to one full
turn after the filter gasket contacts the filter base
surface.
6.
Re-install the filter guard with two 1/4” screws.
Torque screws to 65 in. lbs. (7.3 Nm) each.
7.
Repeat steps 1-6 on the opposite side transaxle
drive.
8.
Drain old oil filters of all free-flowing oil prior to
disposal. Place used oil in appropriate containers
and deliver to an approved recycling collection
facility.
9.
Remove the top port plug from the left side and
right-side transaxles prior to filling with oil. This
will allow the transaxles to vent during oil fill and
prevent any air lock within the transaxles.
