The Avery 40-80 is a tractor in the category of agricultural tractors, produced by the manufacturer Avery. As a representative of the tractor series, this model is positioned in the range of medium to heavy field work. The design is based on a four-cylinder engine that provides a rated power of 80 hp or 59 kW. This technical configuration defines the vehicle's operational scope and determines the compatible attachments and permissible loads during daily operation in the field and on the farm.

The engine output of 59 kW is sufficient to pull typical soil cultivation implements such as plows or cultivators at medium working widths. With an unladen weight of 10,100 kg, the tractor has considerable mass, which ensures good traction on uneven terrain but must be considered in transport logistics on public roads. The drive force is transmitted to the wheels via a transmission. The specific tire configuration with two metal wheels at the front and two metal wheels at the rear is a distinctive design feature that directly influences ground contact and power transmission.

Within the available data on the series, the 40-80 can be classified as a model with a fixed power level. The combination of four cylinders and the specified power class marks a defined point in the manufacturer's product range. This configuration is suitable for tasks requiring high tractive effort at moderate speeds. The metal wheels require adapted driving techniques and maintenance compared to standard tires, but offer advantages in stability and durability under heavy load conditions in certain operational scenarios.

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.
