We're still talking about putting the "972" on the Deere right?
What is the rpm and direction of rotation on the disk head motor? Usually whenever one states the rotation of a shaft, it is when facing the end of the shaft. So if the MacDon head has a pto that spins "counter clockwise
", and if you have a hydraulic motor that spins counter clockwise, they will not work when putting them together. You need one of each when facing the end of the shaft.
The rpm of the motor is not too awefull important as long as it is reasonably close to the MacDon pto speed as the cutter drive speed can be adjusted with pulley/belt combinations.
With the high amount of hp you have on the Deere chassis, you might take a look at some of the older Gleaner combine headers for ideas to run the draper and reel motors. They were a self contained header complete with a reservoir and pump on the header.
If the diskbine motor has as much power as it should have, even though it is not very efficient to run a fluid pump with a fluid motor, as in using the Gleaner head concept, you will have so much hp sitting idle on the Deere anyway, it should not matter in this situation if there is a little loss in efficiency. If the concept works out so well that you start taking orders for dozens of conversions, then you might come up with a more efficient means.
Often there is a trade off or two that has to be dealt with when mounting another manufacturers equipment on a chassis, like header positioning. "If
", the 972 has to be positioned forward a bit to get the clearances you need for the arms and tires, the fluid power drive will accommodate that. The trade off there is that you may be seeing less of the cutter bar and more of the crop exit. But IMO
, that would be just fine in most situations. The Deere chassis should have plenty enough counterweight to carry the MacDon even mounted a bit further forward.
If you do take on this project, is there any way you might be willing to take pictures and share them here? Please?
