Troubleshooting Quality of Cut 7. Verify that there is not a gage wheel or roller pushing the grass down before the blade can cut it. 8. Excessive toe in on front tires can push the grass down to the point where the mower might have difficulty pulling it up to cut it. Check and adjust as needed. 9. Blades that are short or have worn sails do not provide the air flow to stand the grass up. Replace worn blades. 10. The grass may be compacted after being cut. The rear tires and rollers or gage wheels on the rear of the mower will knock the grass down, too. What may appear to be a streak may be grass that the tires or gage wheels did not hit. If so, the rest of the grass will straighten up in a day or so and the lawn will be level. To test for this, brush the grass with your hand to see if it is level. If so, the problem could be compaction. This occurs frequently when the grass is too wet or too dry. 11. On multi-blade decks, what is described as a streak can result from two of the blades not being aligned, and therefore cutting at two different heights; this is actually a stair step cut. On multiple blade mowers the blade tips should be in line within 1/8 inch. See the operator's manual or the section "Checking and Adjusting the Blade Level" of this manual for instructions on checking and repairing this problem. Uncut Grass 1. Verify the correct blade is being used. Some models have different blades for mulching versus bagging. 2. Check the blade pitch. See the Operator's Manual or the section "Checking and Adjusting the Blade Level" of this manual for adjustment instructions. 3. Try a lower height of cut and slower ground speed. Windrow 1. Wet or extremely lush grass windrowing can usually be resolved by following the general suggestions. 2. Dry grass windrowing indicates the operator is trying to process too much grass at one time. One or more of the general suggestions should resolve this problem. 3. If side discharging, ensure grass is being thrown into the previously-cut area.
