Tighten the hex nuts on the front end of the
spring rod until the compressed length of the
spring is 15.9 cm (6.25 inches); refer to

Note:
When operating on rough terrain
decrease the spring length by 13 mm (1/2 inch).
Ground following will be slightly decreased.
Note:
The turf compensation setting will
need to be reset if the HOC setting or the
Aggressiveness of Cut setting is changed.

Operating Tips
Becoming Familiarized with the
Machine
Before mowing grass, practice operating the machine
in an open area. Start and shut off the engine.
Operate in forward and reverse. Lower and raise the
cutting units and engage and disengage the reels.
When you feel familiar with the machine, practice
operating up and down slopes at different speeds.
Understanding the Warning
System
If a warning light comes on during operation, stop the
machine immediately and correct the problem before
continuing operation. Serious damage could occur if
you operate the machine with a malfunction.
Changing Mowing Patterns
This is the most effective method to prevent
washboarding.
Change mowing patterns often to minimize a poor
after-cut appearance from repeatedly mowing in the
same direction.
Scalping, Circle Cutting, and
Verticutting
•
Scalping/Circle Cutting
– Scalping and circle cutting are considered
severe applications. Dedicate reels specifically
to these applications.
– Follow and maintain the 1/3rd rule (cut only 1/3
of the grass blade at a time).
