maximum extension. Completely shut down the tractor and secure in position.
• Mark the inner driveline shield 1/8" from the end of the outer shield.

• Measure the distance from the mark to the end of the inner profile. This length is the amount the driveline
profiles were engaged.
• If the engaged length is less than 12" for a CV driveline and less than 6" for a non-CV driveline, the shaft is
considered too short and should be replaced with a longer shaft.

NOTE: When raising the mower, at least 1" clearance must be maintained between the driveline and the
mower deck. If necessary, place an upper lift stop on the 3-point hitch control lever to limit the height the
