I appreciate the advice on the selection. Is it possible to make do with the smaller 25 hp versions. I see a lot of the work as keeping the trails out to the blinds and down to the lake clear, and the trails really aren't that large. I am afraid that if I buy too large of a frame, that it will be stuck maintaining only the biggest ones and I will still have to get something to do the rest. It seems that the Deere in the 25 HP at the PTO, adn the kubota w/ 25 hp at the PTO all seem to be a relatively good size for trail work.
I am on my third tractor, second new tractor, in five years. An experience shared by many authors on T-B-N.
I started on a borrowed John Deere/Yanmar 750 - 20hp, then I bought a new Kubota B3300SU
light frame tractor-loader - 33hp/25hp PTO. After 420 enjoyable hours decided that I needed more tractor and now have my dream machine, a new Kubota
L3560 heavy frame tractor-loader - 37hp/28hp PTO.
The
L3560 is hardly any larger than the B3300SU, it has hardly any more horsepower, but it is 2,000+ pounds heavier than the B3300SU, much more capable and much safer due to the weight and wider stance. For fifty acres you will get a heavy frame tractor-loader sooner or later. It is cheaper to start out with the right frame from the beginning, besides being safer.
The
L3560 is quieter, vibrates less, and has standard features that make it much easier to connect implements to the Three Point Hitch.
You do not want to operate a tractor at the margin often. At the margin tractors are unstable and the law of averages will catch up to you sooner or later as your operating hours increase. Light tractors are always unstable on slopes. Operating close to the margin stresses the machine, which will require more maintenance and repair.
Keep an open mind as you continue to research.
