A two-wheel tractor works in dust and moisture, under constant load — yet with proper care it can serve for well over a decade. The condition is simple: regular, basic maintenance. We have gathered the rules experienced owners follow: what to do after breaking in a new machine, how and when to change the oil, how to care for the air filter and how to store your equipment off-season. It all takes a few minutes a month and can double your engine's life.
Break-in — the first hours decide everything
A new engine needs breaking in. For the first 5–10 hours, do not push the machine to its limit: avoid deep ploughing in hard, dry soil and long runs at full throttle. After the break-in period, change the engine oil — a new engine sheds microscopic metal particles as its parts bed in. This is the single most important oil change in the life of the machine.
Engine oil — the foundation of everything
Most small-engine failures start with old oil or a low oil level. The rules are simple:
- Check the level before every start — with the engine level and cold.
- Change the oil as the manual says — in practice every 25–50 operating hours, or at least once a season, even if the machine has barely worked.
- Use the oil grade recommended by the manufacturer (usually 10W-30 or SAE 30 for four-stroke engines) — do not mix types.
- Drain the oil while the engine is warm — it flows out faster and carries away more contaminants.

Air filter — clean it more often than you think
A two-wheel tractor works right above the soil, in a cloud of dust — the air filter is its only protection. A clogged filter means lost power, higher fuel consumption and faster cylinder wear. When working on dry soil, check the filter as often as every 5–10 hours. Wash a foam element in warm soapy water, dry it and lightly soak it with clean engine oil; a paper element just needs tapping out, or replacing when visibly dirty. Never run the engine without the filter, even briefly.
Spark plug and fuel
Remove and inspect the spark plug once a season: the electrode should be dry and brick-coloured. Black deposits point to an over-rich mixture or a clogged air filter. Always use fresh fuel — petrol degrades within 30–60 days. Never leave fuel in the tank over winter: it is the most common cause of carburettor trouble in spring.
Transmission, clutch and cables
Once a season, check the gearbox oil level (type and amount are in your machine's manual), grease the cables and joints, and check the free play of the clutch and throttle cables. Tighten bolts and nuts — vibration loosens them even on a new machine. Check tyre pressure too: uneven pressure pulls the tractor sideways when ploughing.
Off-season storage
Before putting the machine away for winter: wash and dry it, drain the fuel (or run the engine until it burns the rest and stalls), change the oil, clean the filter, and coat exposed metal parts with a thin layer of grease. Store the equipment in a dry, ventilated room, ideally on blocks rather than directly on concrete. In spring, fresh fuel and an oil-level check are all it takes to start without surprises.
Quick checklist before every start
- engine oil level,
- air filter condition,
- fresh fuel in the tank,
- tightened working bolts and attachments,
- clutch play and throttle operation.
Five points, two minutes — and a season without breakdowns.
