section frame, out the center of the deck and
through pivot casting in wheel yoke arm assembly.
The rod is a very tight fit; use care to prevent
thread damage during installation.
2. Slide spacers (21) over rods and install washers
(33) and two nuts (34) per rod.
3. Tighten nuts until there is approximately 1 inch of
thread exposed past the nuts. Further adjustment
will be needed once cutter is attached to tractor
drawbar. See Cutting Height Adjustment, page 15.
