What model is the demo?
Alot depends on the design of the rake. I have a khun sr108 and really like it. I have used one similar to a Vermeer WR series ( don't remember the band or model) and it sucked! The height of the main frame and the way they fold up are big factors. The WR was low to the ground and caused heavy/ long stemmed hay to wad up and clog the rake. The way it folded didn't allow it to clear windrows very well. The last wheel on each side would drag hay even when folded all the way up. The frame on the khun is up off the ground more and the wheels fold upwards instead of rearward.
