I've only run a TR270 and TR310 and can't say I'm a big fan. Both were traded in before 1k hours so I can't speak for long term durability.
Things I noticed in my time running the machines
Pros:
The windows come out easy for cleaning both sides.
I appreciate my older Takeuchi more after spending time in the newer Case/NH machines.
Cons:
Cheap/flimsy feel to controls, cab interior, and exterior/engine cover and back door.
The side window screens rattle like mad.
Odd center of balance with light attachments on the front.
Cab ergonomics always felt wrong. Weird seat position compared to controls, foot throttle, etc.
One wrong look, thought, bump, breeze and the radio antenna is definitely breaking off.
Overfill the fuel and it ends up down in the belly of the machine.
If used in the woods, farming, etc anything that ends up on the engine cover screen will end up on top of the engine shortly afterwards. Poor design that just fills up the belly of the machine plus lets everything fall onto the top of the engine.
Cleaning the tracks out takes way more time and effort then it should.
The foot throttle is to flat and makes your ankle hurt after a while. It should be tipped up more like a vehicle.
