Mowing Route Time Audit: Where Crew Hours Really Go

Where a Mowing Day Actually Goes

A mowing crew has a fixed number of paid hours, and the acres it can cut are only part of the story. Much of the rest goes to transit, setup and detail work that rarely shows up on a contract. The fastest way to see the gap is a route log tagged by task, kept long enough to reflect normal days.

The best published clue comes from a telematics study of seven roadside mowers in Fort Wayne. On an average 9.5-hour workday, about 50% of time was spent actively mowing, and the rest was split among crew commute, equipment transport between locations and downtime. That is roadside work, not golf or commercial turf, so treat it as a prompt for your own audit rather than a benchmark.

Your route will differ. Tree lines, cart paths, irrigation heads and slope changes all move the split. The number that settles a staffing decision is the one your own crew produces.

Which Minutes Belong in Which Bucket?

Six buckets cover most routes. Open turf is time with the deck engaged across clean, unobstructed ground. Trim and edge covers string trimming, edging along walks and curbs, and hand work around signs, posts and sprinkler heads. Detail work covers clipping cleanup on hard surfaces, blowing debris off walks and drives, and re-cutting missed strips.

Transit is driving equipment and crew between sites, including loading and unloading the trailer. Setup covers fueling or charging, blade checks, pre-trip inspection and staging the route for the day. Downtime is anything idle or broken, such as waiting on a crew member, a stuck deck, a flat tire or a forced stop. Keeping these six separate is what makes the later math honest.

How Do You Log a Route Without Slowing the Crew?

Keep the log simple enough that the operator can tag it from the seat. A clipboard card or a phone note works, provided the operator records the start time and task code at each change, not every minute. Logging at transitions keeps the burden light and still captures where time moves.

Run the log across different sites and weather rather than one good day. A single site cannot show how a route behaves when turf growth, crew size or traffic changes. Record shift start and end, sites served and the cause of every downtime stop, so a later review can tell a bad day from a bad route.

What Does the Mowing Rate Formula Tell You?

Vendor formulas give a quick ceiling. Exmark publishes two versions: at 100% efficiency, miles per hour multiplied by width of cut and divided by 99 gives acres per hour, and at 80% efficiency the divisor is 124. Ferris uses a similar 80% efficiency basis. These figures are vendor-reported and not independently validated, so use them as planning inputs rather than promises.

Turf Magazine works one example: 7 mph, a 72-inch swath and 80% productivity give about 4.07 acres per hour. Apply that rate only to the open turf bucket. If the log shows four hours of open turf, the formula predicts roughly 16 acres, and every transit or setup hour added on top sits outside what the rate covers.

The same article notes that some companies move to 10-hour days, up to six days a week, to use longer daylight. A longer day adds hours, and the log has to show whether those hours land in open turf or in transit.

A practitioner forum post reports about 2 acres per hour on one job and says rates depend heavily on conditions. Treat it as anecdote, but it is a fair warning that field rates can sit well below a formula.

Why Pattern and Trim Choices Change the Hours

Mowing pattern changes labor. A USGA Green Section Record article compares stripe and 50-50 fairway mowing patterns on a single course, asking which is faster. Read it as one course's result, not a rule. The useful habit is to tag pattern changes separately, so a switch in pattern shows up as a cost rather than hiding inside open turf.

Trim and edge deserve their own bucket for the same reason. Hand edging around walks, bed lines and sprinkler heads can run longer than the mowing it follows. A crew that logs that time as open turf overstates its mowing rate and understates the work that keeps the site presentable.

Which Minutes Could Move to a Supervised Robotic Mower?

The strongest candidates are open turf in clear, mapped zones with predictable edges. Those minutes are the ones a supervised robotic mower can take without a crew member riding the same ground. Trim, edge, detail and most setup stay with people, because they need hands, judgment and tools a robot does not carry.

Service Robot Co. is a full-service commercial robot integrator that stays OEM-neutral, so we match the machine to the zone rather than to one brand's catalog. Our robot leasing runs on a 3-year lease with one fixed robot lease payment, quoted after a site assessment. We then deploy, train and service every unit through our nationwide US engineer network, so one partner covers the lifecycle. A supervised pilot on a single zone lets your log test the claim before more turf moves.

What Labor Surveys Cannot Replace

Industry labor data helps frame the question. GCSAA lists a 2025 Capital Budget and Labor Survey on its operations surveys page. The results I could see contain no mowing-hour figures, and non-members obtain the report through member services. Use it for context on staffing, not as a measure of the hours your crew works.

Survey averages cannot show whether your route loses a slice of every shift to transit. Only a tagged log of your own crew can. Use the survey to size the question and the log to answer it.

How Do You Turn the Log Into a Staffing Decision?

At the end of the log period, total each bucket per route and compare open turf hours with total paid hours. A route where open turf is a small share is limited by setup, transit or detail, so adding a mower does little. A route with long, clean open runs is the candidate for a supervised robot pilot on that zone.

Review downtime separately. Repeated stops for the same cause point to a maintenance or scheduling fix rather than a labor fix. Bring the log, with the route map, to the next hiring decision, lease quote or contract bid, so each one is judged against hours your crew actually spent.
