Make sure the belt is positioned on the
spring side of the belt guide
8.
Reconnect the extension spring
the eye bolt and tension the belt as follows:
•
When properly tensioned, the extension
spring (hook to hook) measurement should
be approximately 8.9 cm ± .63 cm (3.50 ±.25
inch (inside).
•
Once the correct spring tension is attained,
adjust the stop bolt (carriage bolt) until there
is approximately .32 cm ± .152/.000 cm (.125
+.060/-.000 inch) clearance between the
head of the bolt and the idler arm.

Maintenance
Changing the Hydraulic
Fluid
Service Interval: Every 800 hours
Change the hydraulic fluid after every 800 operating
hours, in normal conditions. If the fluid becomes
contaminated, contact your local Toro distributor
because the system must be flushed. Contaminated
fluid looks milky or black when compared to clean oil.
1.

2.
Remove the drain plug on the bottom front of
the reservoir and let the hydraulic fluid flow into
large drain pan. Install an tighten the plug when
the hydraulic fluid stops draining.
