John Deere 8295 RT and 8345 RT – crawler tractors from Waterloo on rubber tracks instead of wheels: six-cylinder engine of 9,000 cm³, 217 to 254 kW

The 8 RT range fits the chassis of John Deere's large 8000-series field tractors from the Waterloo plant in the US with rubber tracks instead of wheels: RT stands for Rubber Tracks. The track drive spreads the high weight of these large tractors over a large footprint, lowering ground pressure compared with wheeled tractors of the same power. The same chassis also forms the basis for the wheeled 8R tractors; on the 8RT, rubber tracks simply replace the front and rear axles.

The register lists 2 versions of 217 to 254 kW (295 to 345 hp) from a six-cylinder engine of 9,000 cm³, torque of 1,310 to 1,515 Nm at 2,100 rpm, unladen weights from 15,600 to 15,700 kg, a lift capacity of 8,754 to 12,700 kg, a length of 5,890 mm, a width of 2,920 mm and a height of 3,320 mm; the engine comes from John Deere itself.

The 8295 RT and 8345 RT are built for tillage on heavy, moisture-sensitive soils, where a wheeled tractor of the same power would tend to compact the ground; in this segment John Deere competes with Case IH's tracked tractors (the Quadtrac concept with four independent track units) and Challenger/AGCO.

On a used example, what counts is the condition and remaining life of the rubber tracks, the tension and wear of the mid-rollers, tightness of engine and hydraulics, and operating hours; spare parts and track belts run through John Deere's dealer network.

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.
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.
