I think you will be just fine with that HP. I’m running a 5 footer with 18hp at the PTO on my JD.
However, i just bought (2wks ago) a DK 4720SE HST and I’ve had nothing but trouble as soon as I unloaded it from my trailer. One thing after another. The first thing I noticed was a coolant leak. I then noticed that I wasn’t able to slowly raise the 3pt hitch… very erratic and jerky for using a quick hitch. When I reached 3hrs on the meter, a strange noise developed in the steering hydraulic area at operating temp… sounds like a failing water pump on a car. At 5hrs, a hydraulic leak developed behind the R5 rear wheel where linkage enters the trans. A real LEMON. it should have been painted Yellow.
Two weeks out for warranty service. However, depending on the complexity of repair, I’ll probably ask Kioti to replace it. You should be aware of the steering wheel noise, as several others on this forum have complained about it... and service techs don’t know how to fix it from what I hear. If you decide to buy it, check the 3pt hitch and try to raise it slowly.
I was really taken back by these issues as my 2009 CT35 Bobcat (Kioti) was a great machine. This is quite frustrating, as I really wanted to like this tractor. At the moment. I’m having buyers remorse And sorry I didn’t check out other brands more carefully.
