420/70R28 EVO-70

The 420/70R28 EVO-70 radial agricultural tyre is a high-quality premium solution from Kabat, designed for medium- and high-horsepower tractors operating in intensive field conditions as well as in road transport. This size is most commonly fitted on the rear axle or—depending on the configuration—used as a working tyre on 4WD tractors, where traction, stability, and soil protection are essential.

This tyre size is most commonly found on agricultural machines such as:

• John Deere 5R / 6M series

• New Holland T5 / T6

• Case IH Farmall / Maxxum

• Massey Ferguson 5600 / 5700 / 6700 series

• Deutz-Fahr series 5 and 6

• Valtra A and N series

• Kubota M5 / M6

Key advantages at a glance:

• Wide cross-section (418 mm) – ensures excellent weight distribution, lower ground pressure, and reduced soil compaction.

• R-1W tread pattern (EVO-70) – deep, wide tread lugs provide high traction, while sliders between the lugs ensure effective self-cleaning and stable performance on both light and heavy soils.

• Carefully engineered lug design – sharp leading edges improve directional stability, while transversely oriented shoulder lugs increase pulling power and help reduce fuel consumption.

• High driving comfort – radial construction and flexible sidewalls effectively absorb vibrations, improving operator comfort during long working hours and transport.

• Optimal tread depth (~43 mm) – ensures long service life and efficient torque transfer to the ground.

Application and construction

• Agricultural tractors with approx. 90–160 HP – ideal for fieldwork, grassland operations, tillage, and transport.

• Universal application – performs well both in the field and on paved roads, offering stability and low rolling resistance.

• Radial construction – improves traction, reduces slip, and lowers ground pressure, protecting soil structure.

• Active self-cleaning – specially shaped tread efficiently removes mud and soil residues, maintaining consistent traction in demanding conditions.

The 420/70R28 EVO-70 Kabat agricultural tyre is very often paired with a 520/70R38 rear tyre, also available in Kabat’s range, creating a well-balanced tyre set for modern agricultural tractors.
