In bidding jobs, I would like to know how you guys allow for the actual expenses of your mower. I can estimate the time it takes to cut a piece of property, materials, gas, etc. The problem I am having is with the mower itself. Someone suggested the formula where you take the value of the mower new and use 1,000 hours as an estimate of its life span. Thus a $7,000 mower would be about $7 per hour. Is this a reasonable figure? Then you would have to add filters, blades, belts, routine maintenance, repairs, etc. What would be a good estimate on these expenses per hour? I am sure this has been discussed many times on the forum, but I cannot seem to find a discussion on this. My searching has been in vain. Thanks for your help.
