Hello. New "member" but I have been a reader/lurker for years.
On our farm in north GA, plus on recreational land, we've used the following: JD 5325 Cab (67hp), JD 3320 (32 hp), Kubota L3130, plus a Kubota L5030 and a JD 5300. Two of the JDs had loaders. I would agree with others who stated that bigger is better on your size property. The longer wheelbase of a full-size AG or utility tractor is much more comfortable, not as 'bumpy' when rolling over uneven ground or holes. Also, the bigger tractors will really dig-in and the added weight helps to pull plows. The JD 3320, while a very nice compact tractor, is outshined by the L3130 because of more weight and longer wheelbase. I bush hog for up to 10 hours a day when I'm on it, and the L3130 is comfortable. The little things like adjustable steering and adjustable seats make a lot of difference. The little L3130 has always done what it needed to do...and much more comfortable than the 3320. That said, the 67 HP tractor had even more weight and more wheelbase, and of course that cab was nice! It was sold, and if/when I can sell the 3320 and L3130, I will have a decision as to either the L4060 or M6060. From experience, the M6060 would prob be a better choice, and does not cost that much more. Also, keep in mind the 'ride height' of the tractor, because with lots of roads you will have limbs hitting you or the tractor the bigger you go...
Either way, there is nothing quite like riding that tractor to melt away the stress! Good luck and enjoy!
Even a "small" difference in tractor frame size can make a big difference in comfort and ability.
(By the way-I am selling the JD3320...and keeping the L3130. It is that much more tractor...)
