Left Auxiliary FourSwitch Handle, part number 6680419 Overview This left auxiliary fourswitch handle provides leftside operator control for up to four auxiliary functions on compatible skid steer and track loaders. It is intended as a direct replacement for the original left auxiliary handle on the listed models and restores lefthand control of auxiliary hydraulic circuits and electric functions. Key benefits Restores leftside auxiliary control for multifunction operation on compatible machines. Consolidates four auxiliary switches into a single lefthand control, reducing operator reach and improving workflow. Matches the original mounting and electrical interface for the listed models to simplify replacement. Core functions and attributes Function: Four auxiliary switches for controlling hydraulic or electrical attachments from the left control location. Fit: Designed to the left auxiliary handle on the compatible skid steer and track loader models listed below. Identification: Part number 6680419 for accurate ordering and replacement. Operation: Provides lefthand access to multiple auxiliary circuits to support simultaneous or sequential attachment control. Compatibility Compatible with the following skid steer loaders and track loaders: Skid Steer Loaders: 751, 753, 763, 773, 863, 873, 883, 963, S100, S130, S150, S160, S175, S185, S205, S220, S250, S300, S330, S450, S510, S530, S550, S570, S590, S595, S630, S650, S740, S750, S770 Track Loaders: 864, T110, T140, T180, T190, T200, T250, T300, T320, T450, T550, T590, T595, T630, T650, T750, T770 Practical applications and scenarios Landscaping: Operate a hydraulic grapple and an auxiliary flow attachment from the left control while maintaining primary lift and tilt control with the right hand. Construction site tasks: Control a hydraulic hammer or breaker and switch to an auxiliary flow for a compaction or broom attachment without leaving the operator seat. Snow removal and grounds maintenance: Use the four switches to operate multiple functions on a snow blower or multifunction front implement, enabling quick transitions between modes. Installation and fit notes Intended as a likeforlike replacement for the left auxiliary handle on the compatible models listed above.
