OPERATING THE MOWER CONDITIONER
7.1.1 Adjusting the Float
IMPORTANT
Float setting (or lifting force) MUST be equal on both ends of the mower conditioner. Left and right ends
require different spring lengths to achieve equal float at both ends.
Follow these steps to adjust the mower conditioner float:
1. Center mower conditioner directly behind the tractor.
2. Raise mower conditioner fully, shut off engine, and
remove key.
DANGER
Stop engine and remove key from ignition before
leaving operator's seat for any reason. A child or
even a pet could engage an idling machine.
WARNING
To avoid bodily injury or death from unexpected
start-up or fall of raised machine: stop engine,
remove key, and engage lift cylinder lock-out
valves before going under machine.
3. Close lift cylinder lock-out valves (A).
4. Back jam nut (B) away from spring.
5. To increase float, turn adjuster bolt (C) clockwise
(further into spring).
6. To decrease float, turn adjuster bolt (C)
counterclockwise (out of spring).
7. Tighten jam nut (B) against spring insert to secure
the setting.
8. Open lock-out valves (A).
9. Lower mower conditioner and check mower
conditioner float at each end.
