DANGER
To avoid bodily injury or death from
unexpected start-up or fall of raised
machine, stop engine, remove key and
engage safety pin before going under
machine for any reason.
Replacing draper
To replace the draper, follow these steps:
1. Raise deck partly up to increase space
between deck and right hand drive tire. First
remove front skid (J) by removing four
nuts (K).
2. Loosen draper tension and push idler roller
inwards as far as possible.
3. Disconnect turnbuckle (Q) and allow deck to
rotate rearwards to increase space between
deck and tire.
4. Pull off old draper and slide on new one.
The draper is bi-directional so the orientation
of the draper does not matter. Tension the
draper.
5. Re-install turnbuckle (Q) and front skid (J).
Adjust front skid to achieve a 1/16 to 1/8 in.
(1.5 to 3.0 mm) gap to draper.
6. Run the new draper and check alignment,
adjust alignment if necessary. Recheck
draper tension after it has run for a few
hours.
Front skid adjustment
Adjust front skid (J) so it is just above the
draper. To adjust, loosen four nuts (K) on front
of skid, position skid height and retighten nuts.
The skid height should be 1/16 to 1/8 in.
(1.5 to 3.0 mm) above the draper. The weight of
the skid should not be on the draper; otherwise it
will cause excessive heat and melt the draper. If
gap is excessive, crop can enter inside draper.
Rear deflector adjustment
The rear deflector (L) prevents crop from
entering inside draper. To adjust, loosen all nuts
(M) along the length of the deck and raise or
lower accordingly. The height should be 1/16 to
5/16 in. (1.5 to 8 mm) above the draper.
