Abstract
A log skidder winch control system (10) includes a manually actuated master cylinder (22) connected to the winch drum brake release cylinder (18) to allow the winch cable (44) to be winched out gradually independent of the vehicle hydraulic system. The master cylinder is connected in the hydraulic line between the winch control valve (34) and the drum brake release cylinder, and normally serves only as a conduit for oil flow to the brake release cylinder when the control valve is put in a 'free spool' condition. With the control valve is neutral the master cylinder can be manually actuated to pressurize the brake release cylinder to provide gradual release of the winch drum brake (26).
