I'm not sure that's going to help, the blades are still going to hit the dirt... you might be able to rig up a weighted 2x4 in front of the axle to drag and help out but you would need to get below where your blades are... myself when I was fighting gophers more I took two identical pallets upside down and tied them together with a chain with slip hooks on the ends and looped the chain at the front boards in the middle and drug that behind the mower, worked really good, easier to drag than my chain harrow...
