THE CHALLENGE
Separate a registered shift from actual tractor use
A large farm needed to check whether recorded driver shifts matched actual tractor use.
A driver signing in did not necessarily mean the tractor was working. The farm operator needed to distinguish time registered on a shift from engine running time and review whether the tractor’s movements matched its assigned task.
The farm also needed starting and finishing fuel levels for each shift so fuel differences could be investigated with the responsible driver.
THE SOLUTION
Link driver shifts, tractor activity and fuel
The farm installed SMART S-4533 trackers with Bluetooth fuel-level sensors, driver-identification readers and engine RPM monitoring.
Defining each driver’s shift
Inserting the driver’s personal card marked the start of the shift. Removing the card ended it: the reader detected that the card was no longer present. A connected relay enabled engine starting after authorization. These events established which driver was using the tractor and the period to review.
Checking activity against the assigned task
A tachometer signal connected to the tracker input supplied RPM, allowing engine running hours to be calculated separately from the card-defined shift duration. The operator reviewed these hours alongside location and movement history. This helped identify shifts where a driver was signed in but the engine remained off, extended periods with the engine running while stationary, or movements that needed explanation. The operator then compared the recorded activity with the assigned farm task. Stationary operation was reviewed in context, since some tractor tasks require the engine to run without the vehicle moving.
Connecting fuel use to the shift
Bluetooth sensors recorded tank levels, allowing the operator to check fuel at the beginning and end of each driver’s shift. Any refuelling during the shift was considered alongside the level change. The operator could then review fuel use against engine runtime, movements and the assigned work before following up with the driver.
RESULTS
Review shifts against recorded activity
The farm operator could compare the registered shift with engine runtime, movement and opening and closing fuel readings.
Periods that did not match the assigned task could be discussed with the driver. The records supported that review rather than automatically labelling all engine-running time as useful work.
WHY SMART S-4533
Check shifts against tractor activity
S-4533 let the farm operator compare a registered shift with engine runtime, movement and fuel changes. A card left in the reader was no longer the only evidence available when discussing whether the assigned work had been carried out.
The operator could identify a period that needed explanation and raise it with the responsible driver. RPM supported runtime checks, not proof of useful work; the task and activity records still needed to be reviewed together.
