Some White sales literature only listed the 42-inch mower deck for the GT-1120. While the 50-inch can be mounted, it may have been considered too much for the tractor's available power. A 40-inch three-point hitch mount tiller was available, model 991-124. The tiller and snowblower required the front/rear PTO shaft kit, 991-219. |
