Alamo TW84 manual Bottoming Out Check Procedure

OPERATION

“Bottoming Out” Check Procedure
• Disconnect driveline from the tractor and slide
the profiles together until fully compressed.
• Place a mark on the inner shield 1/8” from the
end of the outer shield.
• Reattach the driveline to the PTO Shaft.
• Lift Type - Raise the mower/ Pull Type - Turn
sharply and watch the driveline as it
approaches the mark. If the distance between	OPERATION
the mark and the end of the outer shield tube
becomes less than 2” at any point, the driveline
must be shortened. OPS-R-0004_C
Shorten the driveline profiles as follows:
• Remove the driveline from the tractor.
• Position the mower (Lift Type - Raise and
lower/ Pull Type - Turn sharply) to the point 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.
Engagement Check Procedure

•With the driveline attached, position the mower to the point where the telescoping driveline is at its 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.

•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 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. Consult an authorized dealer to

purchase the required driveline length.

NOTE: When raising the mower, at least 1” clearnace 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.
