QUALITY OF CUT PROBLEM SOLVING _________________________________
Make a "test cut" to check the performance of the
mower before you start the repairs.
This area must have turf conditions that are known
and do not change across the area. This type of area
allows an accurate inspection of the performance of
the mower to be made.
Another "test cut" must be done after the repairs or
adjustments to confirm the mower performance.
Before you do a "test cut" to show the cut appearance
and performance of the mower, the following items
must be
confirmed.
These items make sure that the
"test cut" is accurate.

3. The Reel and Bedknife are Sharp.
4. Bedknife Alignment to Reel.
5. Reel-to-Bedknife Contact.
6. Height-of-Cut (HOC).
7. Roller and Roller Bearing Condition.
Washboarding is a repeated pattern of different
cutting heights, that causes an appearance that is
like a wave. In most cases, the wave tip-to-tip
distance is approximately 6—8 in. (15—20 cm).
A change in the colour (from light-to-dark) is also
seen. The cause of this condition can be a
movement from side-to-side in the cutting unit (s).
This condition is found on the mowers with cutting
units held under the machine, but other causes can
give the same result.
Another cause of Washboarding is differences in the
type of turf.
TN0159
Decrease the cut (ground) speed.
Clean the roller and use scrapers or brushes.
Replace the roller.
Change the direction of cut when you use the
machine.
The groomers must be used only in a straight line.
