On really tough tire, that were mounted 30 to 50 years ago, I have used the forks on the tractor and push them down lifting the tractor off the ground, I also bought a bead breaker, 'Bead Cheata', 5500 Bead-Cheata
I have used it many many times, some times 4 to 6 times a day, changing the rear tires on tractors is a lot more work, I just use bars, and bought a air pump off of Ebay a number of years ago, for the transfer of liquid ballast, I finally took the ballast out of the tires it was tearing up the rims more than desired, (I would just pump it into 55 gallon drums, and used a hydraulic hose for a suction hose), and when the tire was fixed would pump it back, Many years ago I bought a coats 20 20 machine, simular to this one, 2020 08 (3)doc size.jpg
