Mowing Crew Hours: A Route Time Audit Before You Change Anything

How do you split a mowing route into hours a robot could take?

A route time audit is a timestamped record of where a mowing crew's minutes go, sorted into seven buckets: open turf, trimming, edging, beds, cleanup, drive time and supervision. Open turf is the work a robot mower can take most directly. Trimming, edging and beds are the detail hours clients notice on the walk up to the front door. Drive time and supervision are the hours a robot changes most, for better or worse.

No public benchmark we could find splits crew hours that way. Searches turned up labor shares and consumer time guesses, not task logs. The audit therefore has to come from your crews, logged before you change a single route.

The number you want is not a total. It is the share of hours that sit on clear open turf, minus the drive and supervision minutes needed to keep a machine moving. That remainder is what a mower could realistically absorb.

What belongs in each of the seven buckets?

Strict definitions do most of the work. A bucket that holds two kinds of minutes will hide the answer you need.

If a crew member edges while a mower runs, log those minutes as edging, not supervision. Mixed minutes are the usual way an audit goes wrong, and they make the robot case look better or worse than it really is.

• Open turf: full passes across lawn with no hand trim needed afterward.
• Trimming: string or blade work at fences, posts, tree trunks and hardscape edges a mower cannot pass.
• Edging: the crisp line cut along walks, curbs and bed borders, often the most visible detail on a lawn.
• Beds: weeding, shaping and clearing planting beds and mulch rings.
• Cleanup: clearing clippings from walks, drives and hard surfaces before the crew leaves.
• Drive time: loading, hauling and travel between properties, and between zones on a large site.
• Supervision: a crew lead watching a machine, checking a pass, clearing a stop or resetting a route.

How do you log a route without skewing it?

Keep one clock per crew and switch it at every task change, not only at the start and end of the day. Record the property and zone on each line so you can compare sites later. Log interruptions such as a client conversation, a sprinkler strike or a stalled machine as their own lines, because those minutes are exactly what a robot pilot will be judged on.

Run the log across several routes, different weather and different property types, over at least two weeks. One wet week or a holiday schedule can move the totals enough to mislead a budget.

What do the public figures tell you, and what do they miss?

A January 2025 Landscape Management interview with an expert described one contractor's P and L at about 45 percent labor, with mowing around 70 percent of direct labor cost. That is an editor's interview, not a formal survey, so read it as one contractor's picture rather than an industry average.

Aspire's May 2025 survey of 1,015 commercial landscape contractors, reported by Mammoth Times in October 2025, covered commercial landscape operations broadly. The summary I found gave scope, not task level hours.

Consumer cost guides from Rising Sun Arts Centre, published in 2026, estimate about 0.5 to 1.5 hours for a quarter acre yard, depending on obstacles and trimming. A midrange job with edging was put at about 2 hours for a two person crew, and another 2026 guide notes that trimming and edging add time to a visit. These are cost guides, not time studies, so use them as a sanity check against your log, not as targets.

Which hours can a robot mower take, and which stay with the crew?

Open turf is the first candidate, but only the clear parts. Trimming and edging still need a person, because a mower cannot reach the detail a client sees at the edge of a walk. Cleanup mostly stays with the crew too, since clippings on walks and drives still need blower or hand work.

A Virginia Tech trial over the 2018 and 2019 seasons compared a STIHL robotic mower with a gas push mower on cool season turf. As reported by Parks and Rec Business, the robot saved time and money. Treat it as a model for running a controlled comparison on your lawns, not as a figure you can copy.

Greenzie, a robotic mower vendor, said in a 2026 announcement that one crew member can supervise an autonomous mower while doing edging, trimming and detailed garden work. As of November 2026, that is a company claim, not an independent result, so test it on your routes before anyone plans around it.

Where do the leaks usually hide in the log?

Drive time and supervision tend to hold the biggest surprises. In a vendor hosted interview, a commercial operator told SiteRecon that the time saved on athletic fields came mainly from removing an operations manager's travel and assigning a dedicated mower to that property. The interview gave no figures, but the mechanism is easy to check in your log.

Look for minutes spent hauling equipment between properties, reloading fuel or blades, waiting for a machine to clear a stop, and crew leads driving out to check one lawn. None of those minutes show up as mowing, yet every route carries them.

What should change once the audit is done?

Do not move a crew member until the log shows enough clear open turf and little enough drive and supervision time to justify it. Start with one property and one route, and judge the result against the same seven categories so the comparison stays honest.

Service Robot Co. builds this check into a site assessment mapping step before any quote. We are OEM neutral, so we pick the robot for the task rather than from one maker's catalog. Once the site is assessed, the quote is a fixed robot lease payment on a three year lease, with deployment, integration, training and service under RoboCare, backed by regional service engineers in every state we service. We can start with one leased unit on one property.
