Tractor two weeks old used the backhoe twice and the stabilizer bar bent downward. The pressure from the hydraulic bent the ends downward. The arms are made from 3" channel Iron. Why did they bend downward? Was the tractor 3720 to heavy for the ends to side together as it raised and thus bent the arms down? It eventually broke a weld on the hydraulic mounting plate. picture / \, instead of sliding together it just bent the metal. Is there anyone else that has had similar problems with JD 375 backhoe?
