Factors That Affect Cut Appearance
In most cases, information provided by the user/customer
will provide the basis for the repairs and adjustments that
are required. However, it is recommended that a “test cut”
be performed to evaluate the mower’s performance
before beginning repairs.
An area should be available where “test cuts” can be
made. This area should provide known and consistent
turf conditions to allow accurate evaluation of the
mower’s performance.
Another “test cut” should be performed after the
completion of the repairs and/or adjustments to verify the
mower’s performance.
Before performing a “test cut” to diagnose cut
appearance and mower performance, the following items
should be verified to ensure an accurate “test cut.”
1. Mowing (Ground) Speed
2. Reel Bearing Condition and Pre-Load (End Play)
Adjustment
3. Reel and Bedknife Sharpness
4. Bedknife Alignment to Reel
5. Reel-to-Bedknife Contact
6. Height-of-Cut (HOC)
7. Roller and Roller Bearing Condition
8. Reel Speed
