5. Lift the motor off the mower deck and lay it on top
of the mower deck.
6. Remove the old belt from around the spindle pulleys
and idler pulley.
7. Route the new belt around the spindle pulleys and
idler-pulley assembly.
8. Position the hydraulic motor on the mower deck after
routing the belt around the pulleys. Mount the motor
to the mower deck with the bolts previously removed.
Note: Ensure that the belt is positioned on the spring
side of the belt guide
9. Connect the extension spring
bolt and tension the belt as follows:
•
When properly tensioned, the inside measurement
of the extension spring (hook to hook) should be
approximately 8.3 to 9.5 cm (3-1/4 to 3-3/4 inch).
•
When you attain the correct spring tension,
adjust the stop bolt (carriage bolt) until there is
approximately 2 to 5 mm (0.065 to 0.185 inches)
clearance between the head of the bolt and the
idler arm.

Hydraulic System Safety
WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Ensure that 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 pinhole
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.
• Seek immediate medical attention if fluid is
injected into skin.
Checking the Hydraulic Fluid
Service Interval: Before each use or daily
The reservoir is filled at the factory with approximately 29 L
(7.75 US gallons) of high-quality hydraulic fluid. Check the
level of the hydraulic fluid before the engine is first started
and daily thereafter. The recommended replacement fluid
is as follows:
Toro Premium All Season Hydraulic Fluid (Available in
19 L (5 gallon) pails or 208 L (55 gallon) drums. See the Parts
Catalog or your Toro Distributor for part numbers).
Alternative fluids: If the Toro fluid is not available, other
conventional, petroleum-based fluids may be used,
provided they meet all of the following material properties
and industry specifications. Check with your oil supplier to
see whether the oil meets these specifications.
Note: Toro will not assume responsibility for damage
caused by improper substitutions, so use only products
from reputable manufacturers who will stand behind their
recommendation.
