1. Position the machine on a level surface, lower
the cutting units, stop the engine, engage the
parking brakes, and remove the key from the

3. Remove the filter.
4. Lubricate the gasket on the new filter with
hydraulic oil.
5. Ensure that the filter mounting area is clean.
6. Install the filter by hand until the gasket
contacts the mounting surface, then rotate it
an additional 1/2 turn.
7. Start the engine and let it run for about two
minutes to purge air from the system.
8. Stop the engine and check for leaks.
Checking the Hydraulic
Lines and Hoses
Daily, check hydraulic lines and hoses for leaks,
kinked lines, loose mounting supports, wear,
loose fittings, weather deterioration, and chemical
deterioration. Make all necessary repairs before
operating.
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Make sure all hydraulic fluid hoses
and lines are in good condition and all
hydraulic connections and fittings are
tight before applying pressure to the
hydraulic system.
• Keep your 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.
• Get immediate medical help if fluid is
injected into skin.

Hydraulic System Test Ports

Use the hydraulic system test ports to test the
pressure in the hydraulic circuits. Contact your
local Toro distributor for assistance.
Use Test Port #1 (Figure 73) to assist in
troubleshooting the hydraulic circuit for the front
cutting units and lift cylinders.
Use Test Port #2 (Figure 73) to assist in
troubleshooting the hydraulic circuit for the rear
cutting units.
Use Test Port #3 (not shown—located on the rear
of the hydrostatic transmission) used to measure
the charge pressure of the transmission.
