What we test

Category T1 — wheeled tractors with a maximum design speed of not more than 40 km/h, a minimum axle track closest to the operator of at least 1150 mm, a curb mass of more than 600 kg and a ground clearance of not more than 1000 mm.

Category T2 — wheeled tractors with a maximum design speed of not more than 40 km/h, a minimum track size of less than 1150 mm, a curb mass of more than 600 kg and a ground clearance of not more than 600 mm. If the ratio of the tractor center of gravity height to the average minimum axle track exceeds 0.9, then the maximum design speed shall not exceed 30 km/h.

Category T3 — wheeled tractors with a maximum design speed not exceeding 40 km/h and a curb mass not exceeding 600 kg.

Category T5 — : wheeled tractors with a maximum design speed of more than 40 km/h.
