Abstract

A protector for a coupler for connecting a drive shaft of an implement to a tractor power take-off (PTO) comprises an elongated shaft having a proximal end and a distal end. The shaft may include a plurality of splines formed around a circumference of the shaft which extend longitudinally along the shaft from the distal end toward the proximal end. The splines may be arranged for meshing engagement with internal splines within a bore of the coupler. A grease zerk fitting may be disposed at the proximal end of the shaft through which grease can be extruded. A channel may extend through the shaft from the proximal end toward the distal end that is in fluid communication with the grease zerk fitting. A plurality of exit ports may be disposed around the circumference of the shaft at one or more positions along the length of the shaft, which are in fluid communication with the channel. Grease may be extruded into the protector through the grease zerk fitting, through the channel, and out through the exit ports to the exterior of the device.

IPC Classes  ?

• A01B 71/08 - Means for protecting against dust or the like, or for cleaning agricultural implements
• A01B 71/06 - Special adaptations of coupling means between power take-off and transmission shaft to the implement or machine
• F16B 7/04 - Clamping or clipping connections
