6.15.4 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 tractor approaches the corner, guide 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 knife 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 mower
conditioner Articulating Power Tongue (APT).
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.
