The dynaflex does have back and forth tilt like macdon, it works great. The main problem I had this fall was with the high skids we had to run tilt all the way forward to cut close to ground. Did a great job only you had to really watch hitting waterfurs straight on or it would un-flex and dig into it. Bent 4 flex arms, had to take out and take to a press, 3 hours downtime, the only problem we had in 350 sep. hrs. on S78, great machine by the way. If we had put rear feeder wedge like our last head we would not of had that problem, ran it 3 years on same ground and never looked back. To make matters worse we got the sch. guards that point down a little instead of up like the high capacity one does. Dan, with the set-up that we are getting do you think I'll have problems pushing? Dan, I have also said that they should make a skid in-between high and low.And why cant they just have a hydraulic cutterbar adjustment like the macdon... Slight subframe piviot?
