McCormick GM: the GM 50 (2011 to about 2016) with a four-cylinder Yanmar diesel engine, 2,189 cm³ displacement, 35 kW rated output and a weight of 1,450 kg
In McCormick's line-up, the GM series stands for compact all-purpose tractors using engines from outside diesel makers, a common approach for smaller tractor brands to avoid developing their own power units. The GM 50 targeted farms with limited space, for example in municipal work, orchard farming or on smaller agricultural plots.

The GM 50 carries a water-cooled four-cylinder Yanmar diesel engine with 2,189 cm³ displacement, which at a rated speed of 2,800 rpm is given, depending on the measurement point, as 49.5 hp gross or 47.5 hp net and 35 kW. At 1,450 kg, with a 1,700 mm wheelbase, 3,300 mm length and 1,396 mm width, it is a compact, manoeuvrable tractor.
With a top speed of 30 km/h, the GM 50 falls under Germany's driving licence category T. A rated speed of 2,800 rpm is noticeably higher than in classic large-displacement field-tractor engines and is typical of compact, short-stroke diesel engines that achieve high specific output for their size despite limited displacement.
When buying a used GM 50, it is worth checking the Yanmar engine's service records, since spare parts can be sourced through the engine maker rather than only through McCormick. The condition of the hydraulics, the clutch and the narrow front axle also need close inspection on such a compact tractor.

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.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
