Do you put a certain percentage of each cut away for future expenses?
Figure mower will need replacement around 2000 hrs.
So as an example:
A $10,000 mower divided by 2000 hrs. Equals $5 for each hour. Plus $1 per hr for maintenance.
Figure about $2 per hr per handheld.
These are aprox only.
You may get 3000 hrs out of your mower.
Ball park on mower gas is about a gallon per hr. Or $3 per hr.
Your insurance you'll have to divide your annual cost by how many hrs per yr you put in.
Truck and trailer you'll have to do your best on that. Cause I've no clue how old it is, or how much life is left in it.
But this gives you a very general idea how much to recoup on equipment costs per hr.
