Cutting Unit Maintenance
Blade Safety
A worn or damaged blade or bedknife can break, and
a piece could be thrown toward you or bystanders,
resulting in serious personal injury or death.
•
Inspect the blades and bedknives periodically for
excessive wear or damage.
•
Use care when checking the blades. Wear gloves
and use caution when servicing them. Only
replace or backlap the blades and bedknives;
never straighten or weld them.
•
On machines with multiple cutting units, take care
when rotating a cutting unit; it can cause the reels
in the other cutting units to rotate.
Checking the
Reel-to-Bedknife Contact
Each day before operating the machine, check the
reel-to-bedknife contact, regardless if the quality of cut
had previously been acceptable. There must be light
contact across the full length of the reel and bedknife;
refer to the Cutting Unit
Operator’s Manual
.
Setting the Reel Speed
To achieve a consistent, high-quality cut and a uniform
after-cut appearance, you must correctly set the reel
speed control (located on the manifold block under
the cover to the left of the seat). Adjust the reel speed
control as follows:
1.
Decide the height of cut at which the cutting
units are set.
2.
Decide the desired ground speed best suited
for conditions.
3.
Use table that follows to determine the
reel-speed setting for your 5-, 8-, 11-, or
14-blade cutting units (
).
