I have a 2004 Worksite Pro 911 hoe attachment that I just had shipped to me. All is fine except the floor peddle that controls the extender is frozen. It won't budge. I assume it's rusted, though there's no rust showing and the whole hoe looks like new. I've put WD-40 on it and hit it all day with a small sledge. Nothing.
What's strange is that this peddle is nothing but a shaft riding in a 3 inch long tube at the base of the valve-control mast. It was clearly assembled at the factory by welding both ends so it's not possible to remove it. Since it's so stuck in there, I've had to disconnect the linkage to the extender valve and operate it by hand. But, that's a hassle.
Has anyone had a similar experience with their foot peddle on this hoe? Is there a history of this kind of problem on these Pro 911 hoes? It just seems mighty strange to have something so simple be so unserviceable! Any advice in how you got yours unfrozen would be appreciated.
