That is the one BIG plus my Kubota round bailer has that my old NH didn't.
The Kubota bailer has a steering wheel superimposed on the bailing screen in the cab with me and the wheel indicates which way I need to move (drive) the bailer to achieve a symmetrical bale each time. If I ignore the steering wheel arrows will pop up and the monitor will beep at me to remind me to drive the bailer in the direction the 'steering wheel is indicating.
Because the bailer is a European design, the bale is completely contained inside the bailer and totally enclosed and is not visible at all from the tractor. There is no way to observe the bale being formed except the steering wheel on the monitor screen. Every bale I roll is (so far) perfect in shape. Don't need 'gathering' wheels on this one either like I did on the my old New Holland baler because it has an extra wide pickup with outboard screw augers on each end of the pickup that moved the hay into the throat of the bailer. They aren't even offered on this one and not needed.
Other thing I really like (and not sure if the JD bailer has it), is, the Kubota bailer has built in variable hydraulic density control. it's all self contained, no external springs at all. The bailer senses the density of the bale and 'squeezes' it according to the pre set parameters, hydraulically. I start them at low density so I can spear them easily and as the bale 'grows' the density increases accordingly. That way, the bale is fiddle string tight but the center is loose.
The entire bailer is totally enclosed so observing the bale is impossible until you eject it.
Farmer down the road has a JD bailer (not sure of the year) but he ran about a hundred wheat straw bales in net and every one was barrel shaped. The other issue with barrel shaped bales is it tends to off track the belts and causes edge wear on them. I have absolutely no edge wear on my belts so far, not even any frayed edges. My NH bailer always developed frayed belt edges from off tracking. Belts are staying in perfect alignment.
I will say my bales look a lot better than before and I don't have to watch anything but the monitor screen and the 'steering wheel'.
Now if Kubota just modified their net insertion from the duckbill design to what JD uses, it would be perfect.
