Tractor Service Hour Tracker
Forecast the next engine oil service for your agricultural tractor from hour-meter readings — hours left, days left and a calendar date.
With your numbers: 2,310 − 2,000 = 310 h since service; interval 300 h leaves -10 h ÷ 5 h/day = 0 days. Follow the OEM service schedule where it differs.
Field notes from maintenance practice
Tractor duty is brutally seasonal: 12-hour days through sowing and harvest, then weeks parked. Enter the season's real daily hours and refresh as seasons change — and plan services into the gaps between operations, because a tractor down for oil during the harvest window costs the crop schedule, not just the workshop bill. Pre-season service plus this forecast usually clears the whole campaign.
Dust is the interval-setter in field work: in heavy-dust operations follow the 'severe service' column and service the air cleaner by restriction gauge, not by hours. Convert the forecast date into action: order filters/parts when the tool shows ~2 weeks remaining, and book the technician at one week. Usage-based scheduling beats calendar-based for any machine whose duty varies — a calendar plan over-services the lightly used unit and under-services the busy one.

About Tractor Service Hour Tracker
This forecaster turns two hour-meter readings into a service plan for a agricultural tractor: enter the meter now, the meter at the last engine oil service, the interval, and average daily use — it returns hours remaining, days remaining and the calendar date to book the work. Farm tractors typically service engine oil every 250–400 h (John Deere/Mahindra/New Holland manuals — 300 h is a common modern figure), with transmission/hydraulic oil at 1,200–1,500 h.

Frequently asked questions
What is the right engine oil service interval for a agricultural tractor?+
Farm tractors typically service engine oil every 250–400 h (John Deere/Mahindra/New Holland manuals — 300 h is a common modern figure), with transmission/hydraulic oil at 1,200–1,500 h. Severe duty — dust, high ambient temperature, heavy loading, short cycles — typically halves the interval, and OEM schedules list separate 'severe service' columns. When in doubt, sample the fluid/condition at the standard interval once and let the result calibrate your real interval.
Should I service before the parked off-season or before the working season?+
Before parking, by the oil's logic: used oil holds acids and moisture that etch bearings during storage, so going into the off-season on fresh oil protects the engine while it sits. Then do a pre-season check (battery, coolant, filters, tires, grease) rather than a full service. Diesel bug treatment in a full fuel tank prevents both condensation and microbial growth over the layup.
My usage varies a lot week to week — does the forecast still work?+
Yes — enter your average daily hours over the last month or two, and refresh the reading every week or two. The forecast date self-corrects as the meter advances. For strongly seasonal equipment, use the season's typical daily hours rather than the annual average.
Hour-meter PM or calendar PM — which should govern?+
Whichever comes first, as most OEM schedules state (e.g. '250 h or 6 months'). Oil oxidises and seals dry out with calendar time even on a parked machine, while wear tracks running hours. This tool handles the hours side; put the calendar limit in your diary as the backstop.
