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, ªsponginessº or attempting to cut off too much grass height may not always be overcome by adjusting the machine. It is important to remember that the lower the height of cut, the more critical these factors are.
Remember that the ªeffectiveº or actual height of cut de- pends on cutting unit weight and turf conditions. Effec- tive height of cut will be different than the bench set height of cut.
Factors That Can Affect Quality of Cut
Factor | Possible Problem/Correction |
|
|
1. Engine maximum governed speed. | Check maximum governed engine speed. Adjust |
| speed to specifications if necessary. If engine is not |
| running at specified maximum governed RPM, reel |
| speed settings may not match ground speed. |
|
|
2. Reel speed and ground speed. | Adjust reel speed to setting shown on REEL SPEED |
| SETTINGS graph for the number of reel blades (5 or 8) |
| and the desired ground speed (see Operatorºs |
| Manual). |
| All reels should rotate at about the same speed. All |
| cutting units should have equal bedknife to reel |
| contact. If checking RPM, do not run reel too long |
| without cutting grass, or bedknife and/or reel may |
| overheat and ªrifleº. |
| See other items in Troubleshooting section of Chapter |
| 4 ± Hydraulic System. |

3. Cutting unit counter balance tension adjustment. |
|
| The counter balance spring on each cutting unit lift arm |
| can be adjusted to compensate for different turf |
| conditions. Decreased counter balance tension will |
| help keep the cutting units on the ground when |
| mowing at higher speeds, and it helps maintain a |
| uniform height of cut in rough conditions or in areas of |
| thatch build up. Increased counterbalance tension will |
| improve traction by increasing weight on the front tires. |
| Also, the spring may be adjusted at the cutting unit |
| pivot point. Raising the spring at the lift tab decreases |
| the cutting unit weight at the outboard end. Lowering |
| the spring at the lift tab increases the cutting unit |
| weight at the outboard end. |
| NOTE: Decreased counter balance tension may lower |
| the actual or ºeffectiveº height of cut. |
|
|
4. Tire pressure. | Check each tire's pressure. Adjust to pressures |
| specified in Specifications section of Chapter 6 ± |
| Wheels and Brakes. |
