I am going to purchace my 1st mower in a few weeks. I have decided to get a 36" , belt driven metro or metro HP. I will be cutting a few lawns with some ruts from water drainage in them . I need to know if the Floating deck will scalp them less or just stick with the fixed. I will be cutting my own new lawn and about 3-5 others. Thanks __ Also are the drive belts hard to change in the field!!
