Tracking Mower Hours by Property to Find Fuel and Wear

What does tracking mower hours by property actually show?

Tracking mower hours by property shows which lawns carry the most fuel burn, blade wear and machine time. Fleet totals hide that. A monthly total says how much the crew used, but not which contract used it.

The method is to record engine hours, fuel drawn, blade sets and acres or visits for each site, then compare them side by side. Most crews already keep pieces of this in receipts, shop tickets and operator memory, but those pieces rarely reach a specific lawn.

Done well, the log shows which contracts absorb a disproportionate share of equipment time, and whether that share is being priced in.

How do you assign machine hours to the right lawn?

Start with the machine, then the job. Each mower needs a fixed identity, and each job ticket needs the machine ID, the site name, and start and stop times. That pairing is the whole method, and it takes little beyond discipline at the start of each visit.

Maintenance software vendors make the same point. Whiparound advises scheduling mowers by hours rather than miles, and assigning each machine to a location, crew or job site even without GPS. It also suggests comparing PTO run time with logged job hours, which can expose hours that never reached a job record.

Machines moved between two lawns in one day are the usual weak spot. Log the transfer as its own line, so the hours split cleanly instead of landing on whichever property was entered last.

How much fuel does an hour of mowing burn?

Published fuel figures are thin, and they swing with engine size, load, terrain and grass. Treat any single number as a starting point for your own measurement, not as a rating to bill against.

Owner reports are the most candid data available. One Tractor by Net forum thread puts a 23 horsepower Kawasaki 61 inch zero turn at about 1.5 to 2 gallons per hour under hard use, and a 31 horsepower diesel at about 0.75 gallons per hour. These are owner figures, not manufacturer data, and they should be read that way.

Some listings give liters per hour for a model class, and those do not reconcile with the gallon reports. Pick one unit, convert from one verified spec sheet, and hold that unit fixed for every property you log.

Then divide the gallons drawn at each site by the engine hours logged there. Tracked over a season, that ratio shows which lawns push the engine hardest for each hour of work.

Where does blade wear show up in the hours?

Blades wear on conditions more than on a clock. Sand, debris, the number of passes, and a deck that meets a curb or a sprinkler head all shorten blade life, so hours alone do not predict a swap.

Hours still give you a schedule and a comparison. Record each blade change against the site it came from, along with the engine hours logged there since the last set. If one lawn goes through sets faster than its neighbors, the cause is usually turf, terrain or obstacles, and the log tells you which property to inspect first.

Maintenance software vendors advise scheduling by hours, so the same counter can drive service intervals and blade planning.

What can telematics split by site, and what can't it?

Connected mowers report hours. Splitting those hours by job site is the harder step. Deere's product page for its Z997R 360 mower describes a modem that transmits engine hours for maintenance planning and utilization balance, and says engine hours can be estimated from key switch data and corrected in Deere's Operations Center. Verify those details on the page before relying on them for your fleet.

Husqvarna's Australian fleet services page describes an app showing daily engine hours of use, with vibration data, project and customer tags, and a workday log of hours used each day. US availability should be confirmed directly. Third party telematics providers, including Motive and iWave, describe engine hour statistics and geofencing, and geofencing is the mechanism most likely to tie hours to a location.

No commercial product we could verify reports mower engine hours split by job site on its own. A vendor patent application describes a connected mower that calculates job profitability from time spent inside a job site perimeter, and an efficiency ratio of prime mover runtime to that site time. That is a filing, not a product, but it shows the calculation worth asking any vendor to explain.

How do you build a comparison of equipment load by site?

Keep the sheet short enough that operators will fill it in every week. For each property, record these five fields:

• Engine hours logged to the site, from telematics or the job ticket
• Fuel drawn in gallons, from pump logs or receipts
• Blade sets fitted, with the date and the site hours logged since the previous set
• Acres or visits completed, so hours read per unit of work
• PTO run time beside logged job hours, as a check on the match

Where would a robotic mower change the numbers?

A robotic mower earns a first look on open turf where the same machine logs long, repetitive hours and operator time is the scarce input. Tight lots with many obstacles, steep grades or frequent stops are harder to judge from hours alone, and they call for a site walk.

Measuring the change needs site data that this article does not supply for robotic mowers. The sensible move is to run the hours log for a full season, rank the properties, and test the highest ranked lawns first. Those are the candidates for a pilot.

Service Robot Co. is an OEM neutral integrator. We help select the robot that fits the turf across manufacturers, then deploy, integrate, train and service it through a nationwide US engineer network. Commercial robot leasing runs on a three year lease with one fixed lease payment, quoted after a site assessment. Bring the log you already keep, and that assessment will show which lawns deserve the first unit.
