GR60 Mowers Only
Shorten the driveline profiles as follows:
• Remove the driveline from the tractor.
• Raise and lower the mower to find the position
with the shortest distance between the tractor
PTO shaft and cutter gearbox. Shut down the
tractor and securely block the mower in this
position.
• Pull driveline apart and reattach yoke to PTO
shaft.
• Hold driveline sections parallel to one another
and measure back 1” from yoke of each shaft
and place mark on opposite section. Cut this
length off with a saw.
• Round off all sharp edges and debur.
• Thoroughly grease then reinstall the driveline.
• Recheck for proper operation.
GR72 Mowers
The GR72 driveline is a bar and welded sleeve assembly and its length cannot be modified as described
above. Contact your authorized dealer or Rhino Customer Service for recommendations to fit the mower to
the tractor if there is a potential problem bottoming out the driveline.
Engagement Check Procedure
• With the driveline attached, position the mower to the point where the telescoping driveline is at its
maximum extension. Turn off the tractor and securely block the mower at this position.
• Mark the inner driveline shield 1/8” from the end of the outer shield.
• Disconnect the driveline from the tractor and separate the two driveline halves.
• 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 9”, the shaft is considered too short and should be replaced with a longer
shaft. Consult an authorized dealer to purchase the required driveline length.
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
mower can be raised. OPS-R-0005_B
