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
manoeuvrability.
a. As the tractor approaches the corner, guide the
tractor sharply away from the crop. Steer the
windrower to maintain a straight cut ahead as
the tractor moves away from the crop.
b. As soon as the sickle cuts past where the new
corner will be, raise the header sufficiently for
skid shoes to clear the ground, then steer the
windrower 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 windrower
APT.
d. Guide the tractor to straddle the last cut
windrow. As the windrower finishes turning,
steer it back towards the uncut crop, align the
header with the crop edge and lower header to
cutting height.
