Hello, This past week I finally joined owners club on an older wheeled 743 and and mt 55 with tracks. Currently using the mt55 on a lawn with weak sod. Temps right now are freezing. I have to dig with with it and the vibration/movement form the machine busting up a few inches of frost is causing slight damage to the turf. Besides the expensive specialty mats for this type of thing what the next best affordable option? Plywood? I have some spare Or would a tarp work? A heavy duty thicker tarp layered? The mt55 is only 2600 lbs. Same questions would apply to the 743. Am I right to assume tires will be more destructive to a lawn than tracks? Thanks
