The JX 1090 U (A) from Case IH is part of the Zweite JXU series. Production: 2004–2008. The engine delivers 91 hp (66.9 kW), has 4 cylinders, with a displacement of 4,485 cm³. Rated speed is 2,500 rpm. The machine is 3,925 mm long, 2,012 mm wide and 2,590 mm high. The unladen weight is 3,855 kg. The wheelbase measures 2,342 mm. Ground clearance is 376 mm. Top speed is 30 km/h. Transmission: 12 V/12 R, 20 V/12 R and 24 V/24 R. The engine is water-cooled. Tyres: front 10.00-16 ASF (A: 380/70 R 24 AS), rear 480/70 R 34 AS. The fuel is Diesel/RME. The bore measures 104 mm. The stroke is 132 mm. The compression ratio is 17.5:1. Construction: unit construction (no separate frame). The Zweite JXU-Baureihe series covers 4 models. Rated output within it ranges from 72 to 100 hp; the JX 1090 U (A) sits in the upper part of that range with 91 hp. Its immediate neighbours are the JX 1080 U (A) below it with 82 hp and the JX 1100 U (A) above it with 100 hp. Unladen weight within it ranges from 3,530 to 3,960 kg; here the JX 1090 U (A) sits in the upper part of that range with 3,855 kg. 1222 Case IH models across 76 series are on record.

Case IH JX U (second generation) – successor with four-digit type numbers: uniform 4,485 cm³ displacement, 53 to 73 kW, JX 1070 U to JX 1100 U models

The second Case IH JX U series replaced the earlier JX U generation and was likewise designed for utility use. The type designation switched to four-digit numbers with the JX prefix and the U (A) suffix; the register covers the JX 1070 U, JX 1080 U, JX 1090 U and JX 1100 U models with four-cylinder diesel engines also capable of running on biodiesel (RME).

The register holds 4 versions rated at 53 to 73.5 kW, with four-cylinder engines of a uniform 4,485 cm³. Weights range from 3,530 to 3,960 kg, with a length of 3,925 mm and a width of 2,012 mm. Heights fall between 2,530 and 2,615 mm, torque between 262 and 293 Nm at an engine speed of 2,500 rpm.

With the same 4,485 cm³ displacement across all four models, the power difference came mainly from injection and boost tuning; the series continued to target farms in the lower to middle power segment wanting a compact all-round tractor for field and yard work.

When buying used, check the engine and injection system, clutch and gearbox, and the hydraulic system; with biodiesel use, take a close look at seals and fuel lines. Rust on the mudguards and cab frame and the condition of the tyres are further checkpoints; spare parts are available through the Case IH dealer network. Compared with the earlier JX U generation, cab layout and wheelbase changed little, so the range remained compact and manoeuvrable in tight yards and narrow lanes.

What to check before buying

Check the hour meter against the service records — a replaced instrument is the most common gap.
Compare the data plate and chassis number with the papers.
Check the weights in the papers against the figures here — attachments change them.
Check front and rear tyre sizes: mismatched pairs strain the drivetrain.
Shift the gearbox cold and warm — jumps only show up at temperature.
Load the hydraulics and watch for sag.
Ask about parts availability for this build year — the running costs hang on it.
