My dealer said not many buy the mulching kit for the Frontier grooming mowers because they do a decent job of mulching without the kit - however after trying it on leaves in my yard today I beg to differ. Has anybody tried the kit? (My mower is a GM1048E.) Looks a bit pricey at about $375. Wondering how hard it is to install and whether it is worth the price. I'm thinking I may try lowering the deck about an inch first - it's still set at the factory height.
