Iseki TE4270 seasonal maintenance — from winter storage to spring start-up

Every season asks something different of your Iseki TE4270. Below are practical tips, based on the maintenance and operating instructions from the manual, supplemented with hands-on experience.

Winterizing (autumn)

• Check the antifreeze. The radiator holds 7 liters; top up with antifreeze where needed so the system is frost-resistant. Frozen coolant cracks the block and radiator.
• Take care of the battery. Fully charge the battery (N70P, 12 V 52 Ah); fully charged electrolyte has a specific gravity of ±1.26 at 20°C. In severe cold, the manual recommends removing the battery and storing it in a warm place — this makes starting the next morning much easier. When disconnecting, disconnect the negative cable first .
• Full fuel tank. A full tank prevents condensation and therefore water in the fuel system.
• Cleaning and greasing. Remove implements, grease bare parts, and store the tractor dry and covered.
• Lubricating. If you've worked in wet/flooded terrain, grease all nipples before storage.

Starting up after winter storage (spring)

• Check fluids. Check engine oil (on level ground, 3 min after shutting off), transmission, front axle, and steering oil, and coolant.
• Connect the battery. When reinstalling, connect the positive terminal first , then the negative — this prevents short-circuiting with tools.
• Tire pressure and tires check for cracks and pressure. You can find the correct tire pressure on the sidewall of the tire or in the manual for your model.
• Warming up. After a long period of standing still, let the engine gradually come up to temperature before working under load.
• Test everything. Check lights, horn, brakes (evenly!), clutch, and hydraulics before use.

Summer — preventing overheating

• Keep the radiator grille clean; grass, chaff, and insects clog it quickly and reduce cooling.
• Check the coolant level more often in hot weather and during heavy work.
• Check the V-belt: a slipping belt causes the water pump to run poorly.

Wet conditions (autumn/spring)

• Grease extra. After working in mud or flooded ground, re-grease the nipples every time — water washes the grease away.
• Engage 4WD for grip on wet/slippery ground, and use the diff-lock only briefly and while driving straight ahead.
