This is my second tractor, but my first that is capable of doing real work on my place. The prior one was a Kubota 22HP toy with a small bucket and a 3-pt hitch and PTO.
For its size it was decent and totally trouble free but it wasn't heavy enough for any serious work. The Kioti DK45SE is plenty for what I need to get done. It's sturdy, stable and reliable and very fuel efficient. I can run it all day on a few gallons of diesel.
The only problem I've had keeping me from rating it 5 stars in the first 2 years I've owned it is a relay in the starter circuit that went out. The tech who fixed it at my place was very quick and said he had seen this fault many times on my model which made finding and fixing it quick and easy.
This model is 4WD and strong. I bought it new and this model and the Kubota were recommended to me by neighbors with much more experience than me. Almost no regrets to date on making this my first real work horse tractor.
