TRACTOR DRAWBAR DIMENSIONS
Be sure the drawbar is adjusted to meet the ASAE
standard specifications as shown here.
On 540 RPM machines, the distance from the end of
the tractor PTO shaft to the center of the drawbar
hitch pin must be 356 mm (14 in).
356 mm (14 in)
FOR 540 RPM
152 -- 305 mm (6 -- 12 in)

On 1000 RPM machines, the distance from the end
of the tractor PTO shaft to the center of the drawbar
hitch pin must be 406 mm (16 in).
NOTE: Using a tractor with nonstandard PTO-to-
hitch dimension can damage the front PTO and, or
the tractor PTO driveline.
NOTE: Ideally the top of the tractor drawbar should
be 483 mm (19 in) above the ground. A low or high
drawbar will affect the driveline angle, header
flotation and cutter bar angle.
IMPORTANT: Do not offset the drawbar from center
or PTO damage will occur. Locate the drawbar
directly below the PTO shaft. Clamp the drawbar so
it cannot be moved from side to side.
IMPORTANT: If the tractor has a three-point hitch,
raise the lower links as high as possible, lower as low
as possible, or remove them, to prevent them from
hitting the tongue and PTO shaft when turning.
