This is definitely the ultimate bead breaker. I use it commercially for my mobile repair business. Based on the pictures, it is difficult to determine its size without something for comparison. Based on its price, I was expecting it to be a smaller unit similar to the many pneumatic impact driven models on the market but was surprised to find out it is a monster heavy duty unit that can handle large ag tires, heavy equipment tires, and 18 wheeler tires. The breaker unit is therefore extremely heavy, but it is a small price to pay considering its capability. I do have one of the screw driven models in the service truck but I hesitate to use it for many agricultural apps because they don't seem heavy enough to deal with ag tires with rusty rims. This breaker has handled absolutely everything I have tried to use it on from grader tires, to heavily rusted 28 inch rim tractor tires. The only criticism I have is the hose is a little too short if you're going to use it to change a lot of large tires while the wheels are still on the equipment. This Is often the route we take when when we can't easily remove the wheel from the lugs and pilot due to rust. According to tech support, it's a 3/8 npt hydraulic hose so shouldn't be difficult to find a longer one if you wanted. If you're looking for a huge industrial unit, this is it.
