Anyone familiar with them? I checked the Bobcat 335, Kubota 121. The JCB dozer blade has to be the best size and design out there. The tracks are several inches wider and longer. I don't care for the fiberglass engine/pump covers and the extreme high idle, with the resulting high noise level. Also wonder how the fuel consumption compares to the others?? Controls are either ISO or SAE. All these models are same price--Seattle area.
