Abstract:
In an agricultural implement including at least one rotary driven tool, a drive coupled to said rotary driven tool including a slip clutch, the improvement comprising:said slip clutch including first and second sections arranged concentrically to and adapted for rotation about an axis; said first section including a fluid tight container adapted for containing a liquid coolant and having at least one end plate; a friction disk mounted to said second section for rotation therewith and for movement toward and away from said at least one end plate; a biasing arrangement mounted to said second section for rotation with said friction disc and being mounted for yieldably frictionally locking said friction disk in engagement with said at least one end plate with a predetermined axial force, whereby when said clutch is overloaded said friction disk and said at least one end plate will rotate relative to each other and will generate heat that is dissipated by said liquid coolant.
