I have looked around on this site for a thread on tractors and I am glad I found this one. I thought I would comment/recommend a slightly different type of tractor. For 12 years I owned a subcompact tractor. These machines look like an overgrown riding mower but have many features of a full sized tractor.
These features include the following:
A Diesel engine
A three point hitch
Hydraulics to operate a loader
Mid and rear PTO’s
These tractors are fairly small but very powerful for their size and can operate a large number of attachments & implements. They are also quite efficient by virtue of the Diesel engine. Mine burned a meager 2/3 gallons per hour. I highly recommend these machines to the landowners who need the extra mechanical help but still want to minimize the impact on the land (they don’t really compact soil).
