The Uniforest GK winches provide a constant pulling force regardless of the amountbof cable on the drum. They are for serious professional use. They are electro hydraulic controlled with a hand held wander lead.  They all have the option of being radio remote controlled. The tractor pto drives a hydraulic pump which in turn drive a hydraulic motor/s which power the drum and applies pressure to the multiple clutch plates.  There is a hydraulic unwinding device that powers the cable off the drum when feeding the cable out. The unwinding speed of the cable can be varied using the flow control valve.  A winding arm and pressure roller help ensure the cable is evenly wound onto the drum when winching in.  The G winches have a high pulling force even with a fully wound drum. Chainsaw and fuel tank holder are standard. They have a highly efficient worm gear drive or  Bevel and helical gear drive. The hydrailic system has a high pressure oil filter. They have a folding window guard. Easy to maintain and control. Optional hydraulic hinged butt plate. The G winches are priced with  syandard size cable, however tere is a choice of cable sizes and length.  There are two top link positions and multiple lower linkage mounting points to suit a wide range of tractor linkages. A PTO shaft is included in the price.
