Rk Other models

The register lists 5 versions with 14 to 55 kW (19 to 74 hp) with diesel engines.

With this span from the compact yard tractor to the mid-range tractor, RK covers a wide field in which Yanmar and Deutz engines provide comparatively straightforward maintenance and good parts availability; the four types marked with H, from RK19H to RK55H, form a coherent series, while the RK74 is listed as the largest type without this suffix; RK tractors are thus aimed at smallholdings and small businesses seeking an easily serviced compact tractor with familiar engine technology.

When buying used, check clutch and gearbox, the tightness of the hydraulics, and the condition and hours of the Yanmar or Deutz diesel engine; parts for these widespread engine families are well available through the general farm machinery trade, while RK-specific attachments are usually found through specialist importers instead.

The PTO and three-point hitch of this compact class follow the standardised ISO 730 Category I at 540 rpm, ensuring compatibility with common implements for yard and municipal work.
