'04 Kioti LK3054:
I'd say mostly poorly placed controls.
1. Ignition switch is right where you hit it with your knee. Never broke a key, but have shut off electrical system many times. Ended up making a guard out of a piece of 1½" PVC.
Same situation with 4 way flasher switch, same solution.
2. PTO lever was right where it would rub on your left ankle when you'd use the clutch, also would catch on pants cuff when getting off. Sawed off lever at bend, a little harder to engage/disengage but better than catching pants leg on lever and landing on head (a matter of when, not if).
3. Shield around PTO shaft was so close to shaft that I couldn't get my hands in there to connect/disconnect. That got taken off in short order.
4. 3PH control a bit flimsy & stiff, also 3PH kind of jerky. Haven't found a solution to that one yet.
5. Can't get at the radiator filter screen if the FEL is attached. I'm guessing this is not unique to this tractor.
No tool box, but not really any place to put one. Other than that, a pretty good tractor.
Volume and Tune knobs on the radio are reversed from any radio I've ever operated in 61 years on this planet. This one has Volume on the right and Tune on the left. Really? What's wrong with just leaving something alone that ain't broke?
Used to see this a lot on Japanese cars from the 70s & 80s. I guess it didn't occur to anyone that it might be inconvenient in a LH drive vehicle.
Be glad they haven't gone to the touchscreen radio/GPS/backup camera setups modern cars have where you have to dig down several menu levels to do anything useful.
