I had a Kubota BX2660 with a 4' bucket, 60" belly mower, 48" tiller, potato hiller, potato digger, 12" single bottom plow, 3ph carryall and I even built a set of disk harrows for it. It was a fantastic wheelbarrow with the loader. The carryall was great for bringing firewood up to the house from the wood shed. Marvelous mower with that 25.5hp diesel. You might go too fast and leave uncut grass behind you but the engine would never change tone. As for the rest of it, well, it isn't a tractor. It didn't have enough ground clearance to dig potatoes once you hilled them. It would plow, but the low gear was painfully slow, high gear was too high for plowing, and the ground clearance issue left the belly scrubbing the edge of the furrow. The little subcompact tiller was built light but that was its downfall. It was too light to get very deep. Forget tilling unless you plowed first. It didn't dig at all. Second, even if you did plow, it still didn't have the weight to get into the soil. The first 4" would be powder but deeper wasn't happening. Another problem was the power steering. The hydraulics were down at ground level between the front tires. I had sticks pop up and tear hydraulic lines. Another design issue was that the transmission cooling fan was mounted around the driveshaft just forward of the transmission. It was plastic and unguarded. Sticks were famous for poking up and taking the fan blades off which resulted in an overheated transmission. Luckily, replacing that inexpensive piece of plastic was so easy. Since the drive shaft was one piece, all you had to do is take the engine mounting bolts out, disassemble anything in the way that would keep the engine from moving forward (radiator shroud and who knows what else) and move the engine forward to get the drive shaft out. If it had been a telescopic driveshaft, you could have just taken one end loose and collapsed it a bit to replace the fan. There was a guy on a tractor forum that was printing two piece fan halves that you could bolt on without taking the driveshaft out. There was talk of custom making a steel fan stout enough that it would just chip any unlucky stick that made it up there.
Bottom line is if you need a landscape maintenance machine for mowing in areas that need 4wd, hauling mulch and bags of top soil and the like (the bucket did a great job of stripping sod off) then the subcompact tractors are just the trick. If you need a tractor, buy a tractor.
