After using 1940's through 1970's utility tractors from Ford, Massey Ferguson, John Deere and Caterpillar, we got a brand new Kubota. It was my father's retirement hobby to keep farming on a small scale.
The Kubota was purchased with the L854 loader. I put the loader on and take it off in a couple minutes and it's really a very cool feature. I push over stumps, move dirt and remove brush like nothing. We've never known that utility tractors could have so much utility with removable implements like loaders. I just wish he would have gotten the backhoe as well to save my poor aching back from digging holes with a shovel.
The L4240 has been extremely reliable and the traction is great. It is lighter than our old tractors, so I would recommend putting weights on the front and on the tires for maximum traction and safety on hillsides.
However, when using the loader, the tractor sometimes feels under powered on the hills. The extra weight of the loader is felt. The HST tranny makes the under powered feeling worse, but easy to drive on hills.
Remember clutches on hills with a heavy load? HST makes hills so much safer and easy to drive in tight places like orchards, but you lose some power. Just need to buy a few more HP for hilly situations.
