Servis-Rhino EC72 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.

•Raise the mower. Drive through a typical ditch which the unit may encounter and watch marks on the driveline. If the distance between the mark and the outer shield becomes less than 2” at any point there is a potential problem bottoming out the driveline and the driveline should be shortened. OPS-R-0004_F

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.

Engagement Check Procedure

•With the driveline attached, raise and lower the mower within its operating range. 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 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_E
