Turning Golf Mower Run Logs Into Quarterly Board Numbers

What does a board actually read in a mower log?

A quarterly board report does not need the raw GPS trace from every pass. It needs a short set of numbers that answer three questions: how much turf was cut, how many machine hours that took, and whether the work stayed inside the windows the club protects for play. The rest of the log is evidence to keep on file, not material for the board packet.

Those numbers already exist in the run log a robotic mower writes. Each run becomes a row with a date, a machine, a zone, start and stop times, the area covered and any stoppage. Roll the rows up by quarter and the board can read turf work the way it reads any other line of the budget: hours, acres and exceptions set against the plan.

The sections below set out the fields a director reads, how to show acres and hold windows without overstating them, and how to keep the page honest when the numbers do not flatter the program.

Which fields belong on the quarterly page?

Seven fields cover most clubs. Anything beyond them belongs in an appendix the board can request, because every extra column dilutes the two or three numbers a director wants to compare with last quarter.

Fields like these let a director ask a useful question. If acres held steady while machine hours rose, the board can ask if a fault or a charging gap is eating the schedule, rather than debating a single headline total.

• Quarter and date range covered
• Machine ID and zone name, so the board sees where the hours went
• Acres covered per zone, taken from mapped boundaries rather than estimates
• Machine hours, summed from run start and stop times
• Scheduled hold minutes and held minutes, as separate fields
• Stoppages with a reason code such as weather, play, fault or charging
• Manual passes that crew made after the mower finished

How should acres covered be shown?

Acres are the figure most likely to be misread, because one word covers two kinds of claim. A vendor rate describes what a machine can do under good conditions. A run log describes what it did. Put the second in the report, and label anything from the first as capacity.

Vendor material shows the gap plainly. FireFly Automatix says its AMP mows at 6 mph, which it equates to 6 acres per hour, and that its larger model reaches up to 25 acres per charge. Toro, with Reesink, lists an autonomous fairway mower at up to 18.5 acres, or 75,000 square meters. Turflynx claims its robotic fairway mower can reduce labor, fuel and maintenance costs by as much as 60 percent. All of these are vendor reported figures and claims, not club results, and no independent golf pilot in the material reviewed publishes a measured rate in acres per hour.

Public data from outside golf is more measured. New York City's three month autonomous mowing pilot in parks covered approximately 80 acres over 53 total mowing hours, according to the city's fleet newsletter. Sugar Land Regional Airport reports an average of 2.48 acres per hour from GPS data on its traditional mowers. Dividing the city's two figures gives a rough average of about 1.5 acres per hour. That is simple arithmetic on the published totals, not a rate the city reported, and it works as a sanity check rather than a target for a fairway.

How do hold windows show up in the numbers?

A hold window is a stretch when a mower must stay out of the way: a tournament morning, a member event, a frost delay or a practice round. Boards often ask whether the mower ran during protected time, and the honest answer depends on whether the log recorded the hold at all.

Log scheduled hold minutes and held minutes as two fields. The gap between them is the number to watch. A line that reads no mowing during holds is a claim. A line that lists scheduled against held minutes, with any overrun dated and given a reason, is evidence a director can check.

An older USGA course care document describes a course logging weekly total hours and estimating labor cost by task, mowing included. That task by task structure carries over well to a quarterly page, even though the document's date was not confirmed in the material reviewed.

Which outside hour figures can a board use?

Benchmarks on superintendent hours are thinner than they look. One GOLF.com article, citing a survey, gives superintendent weekly hours of about 60 in summer, 45 in winter and 55 in spring. A second GOLF.com article citing the same survey gives other seasonal figures, so the two do not agree. Neither should go into a board deck as a benchmark for your own crew.

GCSAA lists a 2025 Capital Budget and Labor Survey Report on its operations surveys page. The contents were not available for checking, so whether it breaks out mowing hours is unconfirmed. Until a club reads that report itself, its own run log is the more reliable baseline.

How do you keep the report honest?

A board trusts a page that shows its own bad weeks. Put stoppages, rain days and fault time on the page with a reason code, and never fold them into a total. Report manual passes too. A mower that finishes the open turf and leaves crews to handle edges, slopes and wet spots has not covered the course alone.

Two habits matter more than the rest. Compare like with like, since a quarter with heavy rain and no holds does not match a dry quarter with a tournament. And date every map change. If boundaries moved after storm damage or tree work, the acreage moved with them, and the page should say so.

What does a fixed lease change in the report?

Service Robot Co. is an OEM neutral integrator that leases robots through financing on a three year lease, with one fixed lease payment quoted after a site assessment. We deploy, train and service every unit under RoboCare, our service plan, backed by regional service engineers in every state we service. For a club, the cost line can read as a fixed lease payment, and the service record for each machine sits with one vendor.

The fixed lease payment does not replace the run log. A board still needs acres, hours and holds to judge whether a mower earns its place on the course. The lease makes the cost side of that judgment predictable from quarter to quarter, and the log tells the board what the machine delivered.
