This pulling power enables the 527 to overcome drag loads created during skidding. Cable Skidding The combination of tractor balance, torque converter drive train and high drawbar pull enable the skidder to offset the weight and overcome drag loads created during winching situations. The 527 winch is a durable and productive tool that delivers an...
