I found info on "Mow More Landscape Supplies" in Turf Magazine and received a 190 page catalog of all types of replacement parts for commercial mowers. Has anyone ordered from them? If so, what is the quality of the products. The prices were great on everything, although I am a little afraid to buy "replacement" parts for things such as filters, etc. Blades, for example, were like $6.50/ea. Any info?
