The hydraulic fluid reservoirs are located on the sides
of the rear cover. 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 tops from the hydraulic
fluid reservoirs and get an oil drain pan.
Lift 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 three ¼” filter guard screws
and filter guard from the ZT-3100
Transaxle or ZT-3400. 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 ¾ to one
full turn after the filter gasket contacts the
filter base surface.
6)
Re-install the filter guard with three ¼”
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.
10) Fill with 20W-50 motor oil (Bad Boy
Hydrostatic oil is recommended) through
the hydraulic fluid reservoirs until it just
appears at the bottom of each transaxle’s
top port (approximately 2 quarts per
transaxle, 4 quarts total). Install the top
port pug into each transaxle as the
oil level reaches this port.
