All the categories for tractors are shown below. “Tractor” means any motorised, wheeled or tracked agricultural or forestry vehicle having at least two axles and a maximum design speed of not less than 6 km/h.

The basic function is its tractive power. The vehicle has been especially designed to pull, push, carry and actuate certain interchangeable equipment designed to perform agricultural or forestry work or to tow agricultural or forestry trailers or equipment.

Category T

Category „T“ comprises all wheeled tractors; each wheeled tractor category is supplemented at the end by an ‘a’ or ‘b’ index according to its design speed:

a) ‘a’ for wheeled tractors with a maximum design speed below or equal to 40 km /h;
b) ‘b’ for wheeled tractors with a maximum design speed above 40 km/h.

Category T1

Wheeled tractors with the closest axle to the driver having a minimum track width of not less than 1 150 mm, with an unladen mass, in running order, of more than 600 kg, and with a ground clearance of not more than 1 000 mm.

Category T2

Wheeled tractors with a minimum track width of less than 1 150 mm, with an unladen mass, in running order, of more than 600 kg, with a ground clearance of not more than 600 mm; if the height of the centre of gravity of the tractor (measured in relation to the ground) divided by the average minimum track for each axle exceeds 0.90, the maximum design speed shall be restricted to 30 km/h.

Category T3

Wheeled tractors with an unladen mass, in running order, of not more than 600 kg;

Category T4

Special-purpose wheeled tractors;

Category T4.1

(High-clearance tractors)
Tractors designed for working with high-growing crops, such as vines. They feature a raised chassis or section of chassis, enabling them to advance in parallel with the crop with left and right wheels on either side of one or more rows of the crop. They are intended for carrying or operating tools which may be fitted at the front, between the axles, at the rear or on a platform. When the tractor is in working position the ground clearance perpendicular to the crop rows exceeds 1 000 mm. Where the height of the centre of gravity of the tractor, measured in relation to the ground, using the tyres normally fitted, divided by the average minimum track of all of the axles exceeds 0.90, the maximum design speed shall not exceed 30 km/h;

Category T4.2

(Extra-wide tractors)
Tractors characterised by their large dimensions, primarily intended for working large areas of farmland;

Category T4.3

(Low-clearance tractors)
Four-wheel drive tractors whose interchangeable equipment is intended for agricultural or forestry use and which are characterised by a supporting frame, equipped with one or more power take-offs, having a technically permissible mass no greater than 10 tonnes, for which the ratio of this mass to the maximum unladen mass in running order is less than 2.5 and having the centre of gravity, measured in relation to the ground using the tyres normally fitted, of less than 850 mm;

Track-laying tractors

Category C

Track-laying tractors propelled by endless tracks or by a combination of wheels and endless tracks, with subcategories defined by analogy with category T.
