We just recently did an entire overhaul on our 220 swather with a 25 foot header. We put in a new schumacher knife and guards and we converted the old EGC wobblebox over to a Schumacher as well. We had the welding shop in town mount the new platform for it and we used our old hydraulic motor since cost of these kits to convert these 220's has just gotten ridiculous. We are cutting right now in green barley for silage with coarse knife which I have been told was good green material and at the moment it is leaving behind a really ragged cut. All the plants are pushed over a little which one of the indicators I believe of a slow knife. I was able to cut the same stuff last week with a worn old knife and guards and a leaky old EGC at about 5 mph and still leave a decent cut. But after the overhaul we go over about 3-4 mph with leaving a ragged cut, I think it should be reasonable to be able to go at least 5-6 mph with a new knife as well and still leave a nice cut.
So here's where the big question comes in. Are the schumacher wobbleboxs geared a little differently than the EGC or something since I'm using the same motor and pump setting as before. Would it be alright to turn up the pump I think from 15gpm to 17.5gpm in order to speed up knife or will this have ill consequences later on to other components like draper motors and reel motor. Or could it be something else. Could low hydraulic oil do this, last I checked it was sitting at 1/4 on the sight glass of the reservoir. Would just like to have this fixed soon since a better cut equals more tonnes per acre in silage.
