RM4X4 – other models: the collective page of four-wheel-drive quads outside the named ranges, from the TRX420FE1 through the TRX500FA6 to the TRX520FE2, 19.6 to 22.1 kW, single-cylinder engines of 420 to 518 cm³

This page gathers the RM4X4 vehicles the register could not assign to a named range – four-wheeled quads with a single-cylinder engine throughout. The designations TRX420 and TRX520 give the approximate displacement class, with the TRX500 in between; the abbreviations FE1, FA6 and FE2 distinguish equipment and transmission variants, the T3 suffix an emission stage. The brand name 4X4 refers to the selectable or permanent four-wheel drive that sets these quads apart from two-wheel-drive-only models.

The register lists here 7 versions with 19.6 to 22.1 kW from single-cylinder engines of 420 to 518 cm³, unladen weights from 355 to 429 kg, gross weights from 465 to 558 kg, lengths from 2,151 to 2,196 mm and a width of 1,205 mm.

Quads of this power class are used in farming for herd checks and light haulage as well as in hunting and forestry, where four-wheel drive provides traction on unpaved ground and slopes. Compared with larger utility vehicles, they score with low ground pressure and the ability to negotiate narrow paths and dense undergrowth.

Used, the condition of the engine and clutch, the propshaft and differential of the four-wheel drive, brakes, axle boots and tyres count, and on models with automatic transmission the condition of the variator and belt; parts run through the respective importer. On machines previously used in hunting or forestry, it is also worth checking the trailer and plough mounting points and rust on the frame and underbody.
