Servicing the Hydraulic

System

Checking the Hydraulic Fluid
Check the hydraulic fluid level as follows:
4. Center sprindle pulley
5. PTO drive belt guide
6. Idler spring
• Check the hydraulic fluid level before engine
is first started.
• Check the hydraulic fluid level after first 8
operating hours.
• Check the hydraulic fluid level after every 25
operating hours.
Fluid Type: Mobil 1 15W-50 synthetic motor oil or
equivalent synthetic oil.
Important: Use oil specified or equivalent.
Other fluids could cause system damage.
Hydraulic System Oil Capacity: 67 oz. (2.0 l)
Note: There are two ways of checking the
hydraulic oil. One is when the oil is warm and one
is when the oil is cold. The baffle inside the tank
has two levels depending if the oil is warm or cold.
1. Position machine on a level surface.
2. Disengage the power take off (PTO) and shut
off the engine.
3. Wait for all moving parts to stop before leaving
the operating position and then set the parking
brake.
4. Clean area around cap and filler neck of
hydraulic tank (Figure 68).

2. Bafe
5. Remove cap from filler neck. Look inside
to check if there is fluid in the reservoir.
(Figure 68).
6. If there is no fluid, add fluid to the reservoir
until it reaches the cold level of the baffle.
7. Run the machine at low idle for 15 minutes to
allow any air to purge out of the system and
warm fluid. Refer to Starting and Stopping the
Engine.
