Troubleshooting
There are a number of factors that can contribute to un- satisfactory quality of cut, some of which may be turf conditions. Turf conditions such as excessive thatch, uneven ground conditions, “sponginess” or attempting to cut off too much grass height may not always be over- come by adjusting the machine.
Remember that the “effective” or actual
Factors That Can Affect Quality of Cut
Factor | Possible Problem/Correction | |
|
|
|
1. | Maximum governed engine speed. | Check maximum governed engine speed. Adjust |
|
| speed to specifications if necessary (see Chapter 3 |
|
| Kubota Diesel Engine). |
|
|
|
2. | Blade speed. | All deck blades should rotate at the same speed. |
|
| See items in Troubleshooting Section of Chapter 4 |
|
| Hydraulic System. |
|
|
|
3. | Tire pressure. | Check air pressure of each tire including castor tires. |
|
| Adjust to pressures specified in Operator’s Manual. |
|
|
|
4. | Blade condition. | Sharpen blades if their cutting edges are dull or nicked. |
|
| Inspect blade sail for wear or damage. Replace blade if |
|
| needed. |
|
|
|
5. | Mower housing condition. | Make sure that cutting chambers are in good condition. |
|
| Keep underside of deck clean. Debris buildup will |
|
| reduce cutting performance. |
|
|
|
6. | Make sure all deck | |
|
| same. Adjust deck as specified in the Operator’s |
|
| Manual. |
|
|
|
7. | Cutting deck alignment and ground following. | Check lift arms and cutting deck pivot linkages for |
|
| wear, damage or binding. Also, inspect for bent or |
|
| damaged pivot shafts. |
|
|
|
8. | Roller and castor wheel condition. | All rollers and caster wheels should rotate freely. |
|
| Replace bearings if worn or damaged. |
|
|
|
9. | Grass conditions. | Mow when grass is dry for best cutting results. Also, |
|
| remove only 1” (25 mm) or 1/3 of the grass blade when |
|
| cutting. |
