The guy I worked for a few years ago had an old Kubota tractor. I don't know what model it was but I do know that it was only about 12hp. I remember this because I always wondered how this tractor that we used to move dirt and trees around with, rototill, grade and bush-hog with could have the same horsepower as the lawn tractor I used to mow my lawn with that could barely make it up my back yard if the grass was wet! Anyway. That tractor seemed quite adequate for what we used it for most of the time. It certainly wasn't the most powerful tractor but generally adequate. Most mfg. don't make tractors this small anymore. The smallest are around 20hp and these are generally glorified lawn mowers (in stature at least). These would include models like Kubotas BX series, Massey Ferguson 1400 series or even John Deere 2000 series. So my question is, how do these new models compare with that old Kubota? Should I expect a small Kubota BX1850 with an 18hp engine to have more power than the old 12hp? And if so, how small of a tractor could I expect to use in a small landscaping operation? I've started the search for a tractor for next season. My main uses at this time are for loading bulk materials to take to a job site, mulch, top soil & compost. I'd like to have something that could do more however, maybe some light grading work onsite, tilling for lawn renovations and moving plants and stone around the job site. How small of a tractor could I realistically look at purchasing to accomplish this. Obviously with a small company, cost is a major factor. What size tractors do you run for operations like I've described and how well do they perform? I'd love any input you can provide.
