I went from a Deere to a JCB 300T in 2018 and love it. Side door is the main reason I switched after trying a  neighbor's JCB. Lots of other good things about the 300T. Engine layout is great, much easier to reach everything than about any other machine I looked at. Cab is roomy as well as easy in and out. Visibility is much better than other machines. 75 hp and engine always starts easily. I looked at Kubota but really didn't like the way the cab door comes in over your head. Felt cramped. I had a problem with a door hinge but JCB replaced it under warranty.  A great machine for an older guy feeding large hay bales on uneven ground and hillsides and scraping tight feed lanes. Excellent lift capacity and stability.
