This is a cool thread, been watching.
As for power steering, on my old Fords it became second nature to use the brakes to help steer. A lot of weight on the back helps too.
I have two different brands of locking grease gun couplers. Neither will fit in the end of the pins on my loader or backhoe. Can anybody with the LocknLube brand confirm or not that they are narrow enough to fit?
