<font color=blue>JD mechanics are saying it is just overall much more rugged in nature than the 54"</font color=blue>
The 60 truly is. I guess that's what I was trying to indicate with my previous epistle-length post. I'm sure the same is true for the 'Bota decks. You should look at the two decks side-by-side. The guide wheels (8" vs 5"), guide wheel supports, gear box support, etc., on the 60 are so much more solid and heavy, I'm certain you will be convinced of the added value for the added expense. I'm guessing that's why you went with the 4100 over a smaller tractor in the first place. Tres is right-on with the versatility. You might think the 54 was easier to handle, but it puts a lot of obstacles closer to your tractor. The 60 is for the JD 400 series and up, exclusiveley. The 300 series can carry the same 54.
I know you are saving your poker change for your deck. Have you looked for an "experienced" 60 to save a few bucks? Like other commercial-grade decks, the spindles and guide wheel bearings will wear first. Barring rust or abuse, I wouldn't be afraid to buy one that was well maintained. Could save you up to $1,000. /w3tcompact/icons/wink.gif
Have a great weekend.
