10.1 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 known turf conditions that 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’s performance.
Before you do a “test cut” to show the appearance and performance of the mower, the following items must be
confirmed. These items make sure that the “test cut” is accurate.
1. Cut (Ground) Speed
2. Blade Sharpness
3. Height-of-Cut (HOC)
4. Roller and Implement Wheel Bearing Condition
5. Blade Speed
10.2 WASHBOARDING _________________________________________________________
NOTE: Arrow indicates direction of travel.
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 color (from light-to-
dark) is also seen.
This cause of this condition can be a movement from side
-to-side in the cutting implements (s). This condition is
found on mowers with cutting implements held under the
mower, but other cause can give the same result.
Another cause of Washboarding is differences in the type
of turf.
Probable Cause Remedy
The cut (ground) speed is higher than normal. Reduce the cut (ground) speed.
Grass attaches on roller. Clean the roller and scraper.
The roller is out of round. Replace the roller.
Cut in the same direction. Change the direction of cut more frequently.
Cutting implements have too much or too little weight
on them.
Use the visual display to transfer weight on or off cutting
implements.
Hydraulic system and implement drive motor
performance is decreased.
Check the hydraulic system performance (pump output,
motor operation, valve operation and relief valve
settings).
