I bought my Kubota seven or eight years ago from my boss' dad. His doctor had told him to give up gardening, so I got it for a song. I got the tiller, bush hog, box-blade, boom and two plows with it, plus a trailer to haul it in.
I use the bush hog to mow my seven acres of prickly pear and weeds we call a front yard. Also to mow between the rows of long-leaf pine. The small size is just right for that job.
The four wheel drive comes in handy when I till up a small pepper patch each year. Other than that, it stays under the shed, as the hours will show. The B7500 is a great small tractor. I'm glad to have it.
