More gauges would be nice. Temp., volt.,fuel, tach, oil plus idiot lights should be standard on the Ds. Placing the battery someplace where it will do minimum damage yet still be accessible would be nice. Also, a battery compartment that would allow a greater latitude of battery sizes to fit. Only loose nut/bolt I have found was a lock nut on the hydro pedal dampening piston. IMO loose bolts/nuts in a new tractor are a reflection on the quality of the set-up/service of your dealer. LIGHTS: the position of the headlights are semi-worthless with FEL on. Place the headlights somewhere else. Like the fenders. Actually front & rear facing lights on the fenders plus an option(wired & mounting brackets factory installed) of high on the ROPS lights(your choice of purchasing spot or trap beams). More fender tire clearance. With ags & chains on my 25D it looks like it would be real tight. Optional quick attach/removal shield protecting the underside of the tractor. Including the hydro filter.
