The 420/85R34 EVO-85 radial agricultural tyre is a premium solution from Kabat, designed for medium- and high-power tractors operating in the most demanding field conditions. This size is most commonly fitted on the rear axle, providing excellent traction, stability, and efficient power transfer to the ground—both in the field and during road transport.
This tyre size is widely used on machines such as:
-
John Deere 6R / 7R series
-
New Holland T6 / T7
-
Case IH Maxxum / Puma
-
Massey Ferguson 6700 / 7700 series
-
Deutz-Fahr Agrotron series 6 and 7
-
Valtra N and T series
-
Kubota M6 / M7
Key advantages at a glance:
-
Wide cross-section (429 mm) – ensures excellent weight distribution of the tractor, reduces soil compaction, and protects crop structure.
-
R-1W tread pattern (EVO-85) – deep, aggressive tread with a large contact area guarantees outstanding traction, high pulling force, and effective self-cleaning in heavy conditions.
-
Precisely designed tread lugs – irregular lug geometry, with a sharp leading edge and a trailing edge set perpendicular to the direction of travel, increases traction while reducing fuel consumption.
-
High driving comfort and stability – radial construction and flexible sidewalls effectively absorb vibrations during fieldwork and road driving.
-
Increased tread depth (~43 mm) – extended tire lifespan and efficient power transfer even under heavy loads.
Application and construction
-
Agricultural tractors with approx. 120–250 HP – ideal for machines intensively used in tillage, seeding, and transport operations.
-
Fieldwork and heavy transport – large ground contact area reduces slip, improves work efficiency, and lowers ground pressure.
-
Radial construction – further reduces unit ground pressure, improves traction, and enhances operator comfort.
-
Active self-cleaning – specially shaped tread lugs and sliders between the lugs efficiently expel mud and soil residues, maintaining consistent traction.
The 420/85R34 EVO-85 Kabat agricultural tyre is very often used in combination with a 340/85R24 front tyre, also available from Kabat, forming an optimally matched tyre set for modern agricultural tractors.
