6.10.4 Square Corners
The following procedure is intended only as a
guide to developing a turning procedure for the
tractor being used. Specific distances are not
given due to the variances in tractor
manoeuvrability.
a. As the tractor approaches the corner, guide the
tractor sharply away from the crop. Steer the
mower conditioner to maintain a straight cut
ahead as the tractor moves away from the crop.
b. As soon as the header cuts past where the new
corner will be, raise the header sufficiently for
skid shoes to clear the ground, then steer the
mower conditioner to the extreme direction away
from the uncut crop.
c. As the tractor passes the corner, steer it sharply
back towards the uncut crop, taking care that the
inside tractor tire does NOT contact the APT
hitch.
d. Guide the tractor to straddle the last cut
windrow. As the mower conditioner finishes
turning, steer it back towards the uncut crop,
align the header with the crop edge, and lower
header to cutting height.
