you are about to make a big investment here....having had the 7040 and now 8540 (12 sp) i can say that the difference between them is huge, not just in the HD transmission w/more gears....the 12 speed also has the higher capacity 3 pt lift. in addition, the transmission lock e brake (much safer! when on & off the tractor frequently), more pto power, hyd. brakes (nice!), longer wheel base for a smoother ride, and more guts in the fel w/the larger frame.....all in all, much more machine imho. do get the hyd shuttle . i would strongly look at the 8540 if u go w/Kubota. good luck
