Suitable for the entire series: Iseki TM15 and TM17, all versions.
Iseki TM15 & TM17: daily check (before every use)
The manual prescribes a quick round of the machine before every use: engine oil level, coolant, fuel, tire pressure, operation of brakes and clutch, steering wheel play, operation of all levers, wheel bolts, lighting and instruments, and a check for leaks and loose bolts. Sounds like a lot, but it's two minutes of work and prevents most breakdowns.
Iseki TM15 & TM17 maintenance intervals
| Interval | Tasks |
|---|---|
| First 50 hours (break-in service) | Replace engine oil, replace oil filter, replace transmission oil, clean hydraulic suction filter. This first service is important: break-in debris needs to be removed. |
| Every 50 hours | Grease all lubrication points with lithium grease (in wet soil or intensive tilling: daily). |
| Every 100 hours | Replace engine oil. Clean air filter element. Clean fuel filter bowl. Check battery fluid. Check front axle oil. Inspect rubber hoses and lines. |
| Every 200 hours | Clean hydraulic suction filter. |
| Every 300 hours | Replace oil filter. Replace fuel filter element. Replace transmission oil. Have steering play and tire pressure checked/adjusted, have throttle and speed adjustment set. |
| Every 600 hours | Replace front axle oil (4WD). |
| Annually | Replace coolant. Check electrical wiring. Check clutch housing for oil leaks via the drain plug. |
According to the factory, the air filter element may be cleaned (tapped out/blown out from the inside) a maximum of 5 times; after that — or if damaged — replace it.
Iseki TM15 & TM17 adjustment values
The manual provides clear adjustment values. Handy for the annual service or if something "feels different":
| Adjustment point | Value | Note |
|---|---|---|
| Clutch pedal play | 20–30 mm | Adjust using the turnbuckle in the clutch rod; tighten the lock nut. Too little play causes the clutch to slip. |
| Brake pedal play | 20–30 mm | Left and right must engage equally ; unevenly adjusted brakes pull the tractor to one side. Adjust via the brake rods. |
| V-belt (fan belt) | 8–10 mm deflection | Using finger pressure at the middle of the belt. Too loose = overheating and poor charging; adjust by tilting the alternator. |
| Steering wheel play | 30–60 mm | Measured at the rim of the steering wheel. |
| Front axle support longitudinal play | 0.1–0.3 mm | Adjust using the adjusting bolt under the front axle support (jack up the front wheels). |
| Front tire pressure | 1.2 kgf/cm² (≈ 1.2 bar) | N version: 2.2 kgf/cm². |
| Rear tire pressure | 1.6 kgf/cm² (≈ 1.6 bar) | Check every 300 hours, and visually during the daily round. |
Iseki TM15 & TM17 safe servicing
The factory emphasizes: always perform maintenance on level ground, engine off, handbrake on, hydraulics locked with the lowering speed knob, and a block under the tiller. If working under a raised implement, always secure it mechanically — the lift must never rest on the hydraulics alone. Let the engine cool down first before working on the exhaust or radiator.
