All grapple models require hydraulic power from the tractor or skidsteer. Grapples come with required hoses and appropriate couplers.
The LXG 210S, 330S, 420S, and 430S require one set of remote hoses (one pressure and one return).
The LXG 320R and 320R require two sets of remote hoses (each with one pressure and one return). One set operates the grapple open / close, the other set operates the rotator.
The LXG 330RP, 420R, 430R and 430RP require one set of remote hoses (one pressure and one return) as well as 12V at 1.5A electrical power from the tractor or skidsteer. These models include a wire harness, switch box and cigarette lighter plug, as well as solenoid-operated valve(s). Default operation is open / close on the grapple head. Operating the appropriate switch(s) shifts the solenoid(s) to operate the rotator, the winch or the boom extension as required.
