Changing the Hydraulic Oil
And Filter
Initially, replace the hydraulic oil filter after the
first 200 hours of operation.
Replace the filter and oil after every 800 hours of
operation.
1. Disengage the PTO, move the motion control
levers to the neutral locked position and set
the parking brake.
2. Move the throttle lever to the Slow position,
stop the engine, remove the key, and wait for
all moving parts to stop before leaving the
operating position.
3. Place a large pan under the hydraulic reservoir
and transmission case and remove the plugs,
draining all of the hydraulic fluid (Figure 69).

Mower Deck
Maintenance
If you raise the machine using only a jack to
support it while you work under the mower
deck, the jack could tip, causing the mower
deck to fall, crushing you or bystanders.
Always secure the machine with at least 2
jack stands when you have the mower deck
raised.
On the top of the mower deck are two links
that connect them to the frame. Connected
to these links are torsion spring that are
under tension (Figure 70). If you disconnect
the link the stored energy in the torsion
spring will be released and could cause the
links to move, damaging your hands or
fingers.
Be careful when removing the mower deck
from the frame and secure the links before
disconnecting them from the frame.
