Built, designed, and tested by a farmer. Hardware provided for mounting the kit to the tractor includes 4 - M8 bolts, 4 - M8 flat washers, 4 - M8 split washers, and 4 - M8 hex nuts.

Tractor extension arms feature a breakaway knuckle. Great in case you hit something to minimize damage. Left and right tractors extension arms included. Extension arms mount directly to cab uprights on the OEM bracket face (our foot will fit to 2" to 3 1/2" on center pattern) Mirror mounting feet mount to a bolt pattern of two bolts, range of 2" to 3 1/2" on center.
