We have a 56 Ford 640 here, I believe it's a 56 640 because the serial number is 621 on top then 83149 under it and it's 4 speed trans, and the pto does not engage. It has a backhoe on it and the hyd pump is bolted on the the pto and that's what drives the pump for the backhoe. Was using it one day and shut it down like normal. The next day the pto would not engage. When you move the handle to engage the pto you feel it trying to engage like the gears bump but it doesn't engage and the hoe is halfway in the ground. Any help will be greatly appreciated. Thanks.
