I have a loader mounted blade on the Kubota L4240. It does fine on the black top and you can run the loader in float. I am having trouble from keeping it from digging in on gravel. I can work the loader up and down myself but my driveway is not very level and it is hard and I can only run 2.1 MPH doing that. I have seen guys with trucks plow on gravel and not dig in and the same for the highway department on back roads. I was on a dirt road today that had been plowed by VDOT with a loader and it was not all messed up. I have heard of people splitting a piece of pipe and putting it on the cutting edge but I think the blade still may sink in. One thing that would help would be a good hard freeze but where I live the ground is constantly freezing and thawing. How should my ski shoes be running, level or slightly higher in front? The ski shoes are 6.5" and they are round. Is there any trick to it?
