sure, align blades in parallel with mower center- line, (i.e. front to back).
5. | Measure |
| of the left blade. Be sure to measure at the |
| blade tip with the blades arranged in proper |
| position. |
6. | To level the deck, (side to side) adjust the |
| threaded link at the left side of the deck (Point B) |
| so that the |
| front blade tip matches that of the left front blade |
| tip. This is done by loosening the jam nuts on |
| the threaded link and tightening the lower nut to |
| raise the deck and loosening the nut to lower the |
| deck. |
7. | Measure the |
| rear blade tip. Again be sure to measure at the |
| blade tip at the rear of the right blade when |

| aligned along the mower centerline. The blade- |
| |
| should be 1/8" to 1/4” higher than the front tip. |
| This is referred to as blade pitch. The same |
| height difference should be true for the left |
| blade, measured front and back. |
8. | To adjust the blade pitch, the deck pitch must be |
| adjusted. Loosen the inner jam nuts at the rear |
| of the horizontal threaded links. Start at Point C |
| to raise the rear of the deck, tighten the front |
| outer jam nut to raise the front of the deck. |
| Adjust the rear jam nut at Point C to take the |
| slack out of the threaded link. |
9. | The final adjustment would be to take the “slack” |
| out of the front linkage (Point C) by adjusting the |
| jam nuts on the threaded link. Loosen the jam |
| nuts and tighten the inner nut to remove “slack”. |
10. | In many cases it will be necessary to adjust |
| deck height using both eyebolt adjustments and |
| pitch adjustment to achieve the correct |
| ground heights. If you remember that the front |
| right blade tip adjustment is fixed and you level |
| to that height, adjusting the decks will be simpli- |
| fied. |
