Yesterday our 36" (beltdrive) WB broke down, and we had to do 9 lawns with only 3 21" mowers and 3 guys. We finished all 9 in about 3.5 hours, which is close to the amount of time it would take if we had the 36" with 2 21" mowers. Most of our lawns are small, and the only difference I could make was that 21" mowers can turn faster than a belt drive. Another remote, possible difference is that the grass was shorter than we usually mow it at. Should I feel like I wasted money on such a large piece of equipment, since we can be almost as productive with 3 21's? Would a hydro fix this problem?
