David, I don't know what kind and size of tractor you have or what size offset tiller you're talking about.

Not necessarily so, in my opinion. The only reason I used an offset tiller was money. I had a 40" tiller that was centered and covered my tracks on both sides when I had a
B7100 tractor. When I traded up to a
B2710, I offset the tiller to cover the right tracks because the tractor was wider than the tiller and I didn't want to spend the money to buy a new tiller. But if you don't yet have a tiller, then I'd look for one just wide enough to completely cover both tracks with it centered.

I
think the concensus of opinion is that the gear drive is stronger and will last longer. Chains
can stretch or break, so I wouldn't argue the point, but I've also heard that the tensioner on the chain provides some shock cushion. Now I don't want to get into any arguments about which is better, but personally, that would not be a deciding factor for me in buying a tiller. The one I had was a chain drive Bush Hog brand that saw about 7 trouble free years of very severe service.

Yes.
