Iseki TH185-TH265 technical specifications per model
Suitable for the entire series: Iseki TH185, TH205, TH215, TH235, TH255 and TH265. In this article we compare the full technical specifications of each model side by side, taken directly from the original Iseki factory manual (chapter "Main specifications"). Please note: within a single model number there are multiple variants (standard Q/B, electronic Q, semi-track S25, low chassis N, high chassis, cabin CY) with slightly different dimensions and weights — the tables below show the most common base version.
Engine and power

| TH205 | E3112-UB45 | 1.123 L, 3-cylinder | 14.7 kW / 20.0 hp | 2500 rpm |

All engines are water-cooled, four-stroke three-cylinder diesel engines, fully developed by Iseki itself (not a bought-in Mitsubishi or Isuzu engine as used in some other Iseki models). PTO power separate from engine power is not published by Iseki.

Tyres, turning circle and track width
| Model | Tyres front / rear | Turning circle | Rear track (factory/range) |
|---|---|---|---|
| TH185 | 6-12 / 8.3-20 | 1.9 m | 800 mm (800-950) |
| TH205 | 6.00-12 / 9.5-20 | 1.9 m | 850 mm (850-1000) |
| TH215 | 6-14 / 9.5-22 | 2.0 m | 880 mm (880-1035) |
| TH235 | 6-14 / 9.5-22 (variants: 24×8.50-12, 7-14/track) | 2.0 m | 880 mm (880-1035) |
| TH255 | 7-14 / 9.5-24 (or track 400 mm) | 2.0 m | 880 mm (880-1035), cabin 950 mm |

Important: the front track is fixed on all models and not adjustable; only the rear track is adjustable within the stated range.
Transmission and brakes
As standard, all models have a mechanical gearbox: main lever with 4 positions, combined with an auxiliary switch with 3 positions (super-low/low/high), together 12 forward and 12 reverse gears. Shifting method: constant-mesh gear system with sliding gears — a classic mechanical gearbox, not a continuously variable drive.
A version with type-plate code "G" was optionally available: a linear shift lever for forward-neutral-reverse, combined with an 8-position clutchless main gearshift and a 3-position auxiliary switch, together 24 forward/reverse gears. Iseki itself calls this "HST", but functionally it is a lever-operated gearbox with fixed positions — not a stepless pedal system.
Clutch: dry single-plate clutch with pedal (all models). Brakes: wet disc brakes. Power steering: standard on all models.
PTO speeds
| Model / version | PTO forward (3 positions) | PTO reverse |
|---|---|---|
| TH185, TH205 (Q/B) | 523 / 783 / 1184 rpm | 505 / 757 / 1145 rpm |
| TH205 (GQ/HST) | 559 / 837 / 1265 rpm | 532 / 798 / 1205 rpm |
| TH215, TH235, TH255, TH265 (Q/B) | 523 / 829 / 1218 rpm | 505 / 802 / 1177 rpm |
| TH215, TH255 (GQ) | 559 / 886 / 1301 rpm | 532 / 844 / 1240 rpm |
PTO shaft: 6-spline, Ø35 mm — the same on all models. The semi-track version (S25) does not have a third (fine-work) position and no reversible PTO.
Basic maintenance for these engines: Engine oil filter Iseki TM | TH | SXG | SF (SKU-002/6), suitable for both the E3112 and E3CD engine.
