Servicing the Hydraulic
System
Hydraulic Fluid Type: Toro
®
fluid or Mobil 1 15W-50.
Important: Use fluid specified. Other fluids could
cause system damage.
Checking the Hydraulic Fluid
Service Interval: Every 40 hours—Check the hydraulic fluid
level.
1. Position the machine on a level surface.
2. Move the speed-control lever to the N
to stop the machine.
3. Disengage the PTO, engage the parking brake, shut off
the engine, and wait for all moving parts to stop.
4. Allow the engine and the hydraulic system to cool for
10 minutes.
Note: To get the correct reading, check the hydraulic
fluid level when the machine is not hot.
5. Lift the hopper up.
6. Clean the area around the dipstick of the
hydraulic-system reservoir
7. Remove the dipstick from the hydraulic reservoir
(Figure 67).

9. Remove the dipstick and look at the end
If the fluid level is at the Add mark, slowly pour only
enough fluid into the hydraulic reservoir to raise the
level to the full line.
Important: Do not overfill the hydraulic units
with fluid as damage may occur. Do not run the
machine with the fluid below the add mark.
10. Install the dipstick.

WARNING
Hydraulic oil escaping under pressure can
penetrate skin and cause injury.
• If hydraulic fluid is injected into the skin it
must be surgically removed within a few
hours by a doctor familiar with this type
of injury. Gangrene may result if this is
not done.
• Keep body and hands away from pin hole
leaks or nozzles that eject high-pressure
hydraulic fluid.
• Use cardboard or paper to find hydraulic
leaks.
• Safely relieve all pressure in the hydraulic
system before performing any work on the
hydraulic system.
• Make sure that all hydraulic fluid hoses
and lines are in good condition and all
hydraulic connections and fittings are
tight before applying pressure to hydraulic
system.
Replacing the Hydraulic Filter
Service Interval: After the first 100 hours—Change the
hydraulic filter and reservoir hydraulic
fluid when using any type of fluid.
Every 250 hours—Change the hydraulic filter and
reservoir hydraulic fluid when using Mobil
(more often in dirty or dusty conditions).
