Turby, we sell three different paint schemes of tractors which gives us a good handle on about 6 makes of compacts! They do not all perform to use the word loosely (about) the same. I'll go with the fact that they all have big tires on the rear and small ones on the front. They have a seat mid way and are equipped with a roll bar and at least one hydraulic pump. After that it is a matter of how they use the parts and what the parts are made of. The longeviety of the products stands out as some we call three thousand hour tractor! That means for a commercial guy, his repair incident becomes to much with about 1500 to 2000 hours with what we call nickel and dime problems till about 3000 hours and then it will begin to need a major repair. We see some makes that will go three thousand hours plus without repairs and still doing daily work. Tractors are built differently and to a home owner it may not make that much of a difference as the hours are only about 50 to 100 a year. With a commercial account some put on the fifty hours in a week!
