Iseki TM15 & TM17 buying guide: which one suits you?
Iseki TM15 & TM17 buying guide: which one suits you?
Considering buying an Iseki TM15 or TM17? These compact 4WD tractors from the Iseki TM series are popular grey-import machines: small enough for the vegetable garden, paddock, or orchard, yet with a full-size PTO and three-point hitch. In this buying guide, we outline the differences between the TM15 and TM17, explain the different versions, and provide a checklist for buying a used unit — based on the original Iseki factory manual.
Suitable for the entire series: Iseki TM15 (TM15F) and TM17 (TM17F), in all versions (P, P1, ND, NDP, NDP1, U, and S).
Iseki TM15 & TM17: what kind of tractors are they?
The Iseki TM series is a range of compact four-wheel-drive tractors that, according to external sources, were built indicatively from 1995 to 2002. Originally made for the Japanese market, they came to Europe as grey imports. With a length of roughly 2 meters, a width of just over 1 meter, and a weight of 535 to 580 kg, these are true garden and hobby tractors. Both models feature a water-cooled 3-cylinder diesel engine, 6 forward and 2 reverse gears, and a PTO with three speeds plus a reverse setting.
Iseki TM15 vs TM17: the differences
| Component | TM15 (TM15F) | TM17 (TM17F) |
|---|---|---|
| Machine code | T0284 | T0294 |
| Engine | Iseki E393 | Iseki E3100 |
| Displacement | 928 cc | 1,006 cc |
| Power | 10.9 kW / 14.8 hp at 2500 rpm | 12.1 kW / 16.5 hp at 2500 rpm |
| Max. PTO power | 9.8 kW / 13.3 hp | 10.8 kW / 14.8 hp |
| Weight | 535–580 kg (depending on version) | 565–580 kg |
| Standard tiller | ARM12 (120 cm) | ARM13 (130 cm) |
Beyond this, both models are technically almost identical: same transmission, same brakes, same lift, and same chassis. Do watch out for engine parts: the TM15 has the E393 engine (928 cc) and the TM17 the E3100 (1,006 cc). Many parts, such as the water pump, thermostat, and glow plugs, fit both engines, but always check the engine type on the ID plate when it comes to engine-specific parts such as gaskets.
Iseki TM15 & TM17 versions: P, ND, U, and S
| Version | Features |
|---|---|
| Standard / P / P1 | Tires 5.00-12 front and 8-18 rear, ground clearance 290 mm. P versions have a safety frame (ROPS). |
| ND / NDP / NDP1 | Lower version with tires 5-12 front and 8-16 rear, ground clearance 265 mm, and a slightly shorter machine (2000 mm). Driving speeds are a fraction lower. |
| U | Version with power steering (U-type); transmission capacity here is 14 instead of 13.5 liters. |
| S | Version in which the engine is stopped via the main switch (as with the TM17); the standard TM15 has a separate stop button. |
Height varies per version from 1190 mm (ND without frame) to 1965 mm (P1 with safety frame SF160). If the machine will be stored in a low barn, be sure to measure which version you have.
Iseki TM15 & TM17: what can you use them for?
With 13 to 15 hp at the PTO, these tractors are built for light ground work and maintenance. Think of: tilling with the included ARM12/ARM13 rotary tiller (120–130 cm wide, up to about 16 cm deep), mowing grass with a flail or rotary mower up to roughly 1.2 meters, snow clearing, and transport with a small trailer via the fixed towing hitch. The difference between engine power and PTO power matters here: of the 14.8–16.5 hp at the crankshaft, 13.3–14.8 hp remains at the PTO. So the TM series is too light for a heavier tiller or a large tedder, but perfectly suited for garden, meadow, and orchard work. With a turning circle of just 1.7 meters, it's also easy to work on tight plots.
Iseki TM15 & TM17 market value: what does a used one cost?
The TM series holds its value remarkably well — a sign that these machines are sought-after and reliable. An indication of the current price range (reference date July 2026, based on current listings from European dealers):
| Condition | Indicative price |
|---|---|
| Well-maintained dealer machine, low hours (500–1000 hrs), often with tiller | €4,000 – €5,000 |
| Average condition, higher hours or private sale | €2,500 – €4,000 |
| Project machine (starting problems, smoking engine, worn clutch) | below that — factor in overhaul costs |
For reference, from recent listings: a TM15 from 2000 with just over 600 hours was listed by a dealer for around €4,600, and a TM17 from 2000 with just over 800 hours for around €4,100. Prices vary by country, version, and whether the original tiller is included — that tiller alone can quickly represent a few hundred euros in value. A "cheap" TM with starting problems or blue smoke isn't necessarily a bad buy: glow plugs, filters, and even piston rings are affordably available, but be sure to factor that into your offer.
Iseki TM15 & TM17 used: what to look out for
From practical experience and owner feedback, a number of standard checkpoints emerge when buying a used TM:
| Checkpoint | Why |
|---|---|
| Cold start | Have the engine started from cold. Difficult starting often points to worn glow plugs, a contaminated fuel filter, or air in the fuel system. |
| Clutch and thrust bearing | Engage the clutch and listen for squealing or grinding noises: the thrust bearing is a known wear part. Pedal play should be 20–30 mm. |
| Start safety switch | The engine should only start with the clutch pedal depressed. If it starts without this, the safety switch is faulty or bypassed. |
| Front axle (4WD) | Check the front axle oil (2.7 liters) for milky contamination and listen for play; the front axle support should have no more than 0.1–0.3 mm of longitudinal play. |
| Steering play | A maximum of 30–60 mm of play at the steering wheel rim is normal; more indicates wear in the steering box or tie rods. |
| Smoke under load | White smoke indicates a contaminated air filter or too much engine oil; black smoke points to incorrect fuel or injector problems; blue smoke indicates oil consumption (piston rings). |
| Coolant | Rust-brown or bubbling coolant indicates a blown head gasket — negotiable, but factor in the repair cost. |
| Hour meter and maintenance | Ask about maintenance: engine oil should be changed every 100 hours, transmission oil every 300 hours. |
