CK series vs DK

Hi,
I've been eyeing up the CK35xx but started to think maybe I should go up in power a bit. That takes me to the cross over between CK and DK. DK45xx being around 20% more expensive that CK50xx.

As far as I can see the dimensions are similar. The engine looks the same. Could anyone give a quick run down on the differences? And anyone who decided one way or the other, what were the deciding points?

The DK is heavier, wider, has more ground clearance, lifts more, has a higher top speed, etc. I compared 2 similar the ck4020seh and the dk 4220seh. Just plug in whatever you are comparing.

The DK series gives you a 16x16 transmission with hydraulic shuttle, while the DK is a 12x12 synchronized shuttle and dry clutch.

The DK series is about 15% bigger and heavier. It also has a wet clutch for the 4WD, which then gives you a switch to select between Auto - Off - On. In Auto it will engage the front axle when you press the brakes so you get braking action on all 4 wheels.

DK series has more hydraulic flow on the main pump, so faster hydraulics than the CK series.

This I can't confirm for Kioti 100%, but it may also be the case as the TYM F/15 series vs the 20 series. The 20 series (equivalent to the DK series) has helicoidal gears for the range gears, while the F/series series (equivalent to the CK series) has straight cut gears. Helicoidal gears are a lot quieter making for a overall quieter transmission.

I'm sure there are a lot more differences more noticeable when checking both models in person. Also, make sure you sit on both to get a feeling for how much space you have and all the controls.
