The concern is that years ago I was told by someone at the dealer that it is a bad idea on this particular model of tractor. (I'm not certain, but it may be that these are FWA rather than true 4WD systems, so have lighter-duty front wheel drive than some other designs?) Since then others (not at the dealer) have said "not a big deal". I want the real story, so I'm trying to verify whether there is some "official" recommendation from the manufacturer or not. New Holland has given me the run-around ("talk to your local dealer"). I'd like to know if NH has issued any specific guidance on this, rather than rely on the opinion of whomever I talk to at the dealer.
If my entire winter was spent driving around in deep snow or ice conditions, I might be less concerned. That's not the case around here. Since I'm unlikely to take the chains off every time the snow melts, nor every time I take the tractor out on paved roads, it's a question to which I'd like a definitive answer.
