How much of an issue is the walk-behind traction? I would be looking likely at the 48"/24HP model and would be spending a good amount of time walking behind it, on slopes. What model do you have?
Do you have front/rear weight distribution figures (%)?...for the 2010 48"/24HP 74568?? What is the total weight limit and individual weights (lbs) of the optional weight kit for the Grandstand?
