my co only keeps just enough equipment to do the work for the week. That is 2 mower going 5 full days a week balls to the walls and no back up mower at the shop. My boss banks on the fact that in a event of a break down the dealer will bend over backwards and get ours up and going or have a demo to use. So far we've been lucky cause the dealers have been good but i wouldnt count on it every time. The owner belives that a mower that has value sitting at the shop not producing is depreciating asset I see his point but I dont know of any company that doesnt have a back up of some kind. My guess is that you guys problably have backups???
