First, my mowing conditions. Atleast once a week (some times twice) I mow 3 acres of yard. The terrain is somewhat rough in areas and does have some areas with slope (nothing major, but this is West Virginia). My lawn for the most part is very open without that many obsticals. We have lived at this home for 8 years and riding mower #3 is getting ready to kick the bucket. We have been purchasing Craftsman riders in an assortment of setups. The current one is a Kohler engine, hydrostatic drive, and I believe a 50 inch deck. In this current mower the deck is absolutely wore out and will have to be replaced, also the front axle seems to be messed up as well. The common problem with all mowers (except the one where the hydro transmission went out) is that the deck wears out and we are left with a mower that runs fine, but at the cost to replace a deck, it seems to be cheaper just to replace with a new mower. Also, in an effort to lengthen the life of the current mower, we haven't mowed at near the fastest setting. So, I pose my question again, would you reccomend a commercial ZTR? Currently it takes a solid 3 hours to mow the lawn, and at atleast once a week, time is money. Will these mowers last long enough to justify the extra cost over the craftsman even with time decreased?
