Has anyone tried the Sunshade built for a Grasshopper lawnmower?   It's  $550.   I spend about 5 hours a week mowing and really need to get some protection for my older skin.    Is it durable.... after you trim all your trees?     Does it protect you?   It is Aluminum not steel.   But,  I think canvas would be a waste of time and money.   Looking for any  thoughts or comments
