Equal Angle Driveline Adjustment Procedure
(Not available on 1000 RPM 1-3/4”-20 mowers)
Set drawbar length measured from PTO shaft end to hitch hole at 14” for 540 and 16” for
1000 RPM operating speeds. Position carrier bearing to align driveline in as straight of line as possible. Make
certain that the Yokes on the Driveline and the Equal Angle Jackshaft are aligned with each other, otherwise the
drivelines will not phase properly, possibly causing damage to your machine.

Position the length of the drawbar from the end of the

a 540 RPM unit, position the drawbar length from shaft
end to hitch hole at 14”. For 1000 RPM mowers, set
the drawbar length at 16” for 21 spline 1-3/8” mowers
and at 20” for 1-3/4” 20 spline mowers.
