The Mulching Head Is Your Longest Lead Item
A rotor bearing lets go, the machine sits two weeks, and the note, the insurance, and the shop time keep billing while revenue sits at zero.
Most subs can throw a second crew at a job when a tool breaks. Your crew is the machine, and a replacement takes months to get here, so one failed rotor bearing takes your whole production capacity offline at once. The wear is also continuous and predictable in hours, which means you're accruing a real cost on every acre whether or not anyone writes it down.
The size of it
A single unplanned rebuild in the middle of a season can wipe out the profit from the jobs that funded it, and most owners never see it coming because undercarriage and rotor wear never reach a job cost report.
No published benchmark reference breaks this trade out on its own. CFMA reports at NAICS level, and at that level this trade rolls into a broader bucket with several others. That's why this page carries mechanisms and no margin figures. It reports inside NAICS 238910 Site Preparation, so there's no land clearing margin figure to put in this box. The 48 trades that do publish average 7% net profit at $1M–$5M before taxes, which is the nearest reference point worth anything here.
There's no submittal package and no switchgear on your critical path. The long lead item is a track machine and a mulching head, and OEM order to delivery on new iron runs months, with dealer backlogs pushing it further. Behind that sits a wear schedule measured in hours: tracks around 1,000, full undercarriage around 2,000, plus teeth, hydraulic lines, and rotor bearings that fail on their own timetable. Operators report about an hour of routine maintenance for every eight or nine hour day, before anything unplanned happens. Revenue here is machine hours, so a machine in the shop is a revenue line reading zero.
Three moves, in order
Step 02: Equipment cost basis
A true internal rate per machine covering ownership, maintenance, fuel, and transport, charged to the projects that used it.

What land clearing owners ask
How do i cover the machine payment when the mulcher is down?
A rotor bearing lets go, the machine sits two weeks, and the note, the insurance, and the shop time keep billing while revenue sits at zero.
What does it cost?
A single unplanned rebuild in the middle of a season can wipe out the profit from the jobs that funded it, and most owners never see it coming because undercarriage and rotor wear never reach a job cost report.
What do I do first?
Set an hourly ownership and wear rate for each machine covering tracks, undercarriage, teeth, and major components, and charge it to jobs by the hour the same way you charge an operator.
Are there published benchmarks for land clearing?
No, and this site won't print one. No published benchmark reference breaks this trade out on its own. CFMA reports at NAICS level, and at that level this trade rolls into a broader bucket with several others. That's why this page carries mechanisms and no margin figures. In the surveys it rolls into NAICS 238910 Site Preparation, so the closest honest reference is the 48-trade table, where net profit at $1M–$5M averages 7% before taxes. Read that as the neighbourhood, and read your own job costing as the answer.
Which part of the system fixes it?
The step is number 02, equipment cost basis. A true internal rate per machine covering ownership, maintenance, fuel, and transport, charged to the projects that used it. It comes from chapter 2 of CONTROL: The Construction Financial Operating System.
Josh Luebker ran commercial construction projects before he ran the numbers behind them, on data centres, military bases, hospitals, and high-rises. He wrote CONTROL: The Construction Financial Operating System, which is an eight-step framework for commercial subcontractors, and it publishes on October 1, 2026. He is a master electrician who moved into the office and kept the field vocabulary.
Sulphur Prairie Operations LLC maintains the benchmark reference behind these figures. Every edition is reconciled against the newest CFMA survey release before it publishes here. Where a figure changes between editions, the older edition keeps its year in the title so a citation to it stays correct.
