Troubleshooting

Cutting unit troubleshooting is broken down into two
areas: Quality of Cut Appearance and Mechanical.
Quality of Cut Appearance Troubleshooting, as the name
states, evaluates the mower's performance by the visual
appearance of the cut delivered by the mower.
Undesirable patterns and other conditions noted may be
caused by various mechanical, environmental (variations
in turf, grass conditions, weather, etc.), or operating
conditions.
Mechanical Troubleshooting is related to operational
problems that may or may not be related to quality of cut
problems (reel drive does not engage, etc.).

Quality of Cut Troubleshooting

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. Engine 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
7. Bedknife Application (Correct Bedknife)
8. Roller and Roller Bearing Condition
9. Reel Speed
10. Traction (Drive) Speed
