I’m looking to make a silage pusher , I have things lying about to construct one either from an old axle with wheel or a yard scraper. Either way I ideally want to not have to uncouple shear grab to put in something, just something I can slot tines into and push along then just drive out and leave it. I don’t have centre passages so only pushing up one side at any time . Could do with some pictures or designs I could look at . Simpler the better
