Take the bolt out that handle pivots on then pull the pin, spring, handle assembly out of the Bobtach. Clean the pin and inspect for bend. Apply a light coat of grease. Clean the pin bore of the Bobtach and make sure the grease zerk is not plugged. Put it back together, pin should slide easy. Then grease the pins everytime you grease rest of the loader pivots whether you indend to take bucket off or not. 2-3 pumps of grease each time to keep the pin loose.
