From today, 20th May 2018, roadworthiness testing is mandatory for fast tractors which are used for transporting a load that isn’t related to agriculture, horticulture or forestry operations, and which are used more than 15 miles from their operating base. A fast tractor is defined as one that is capable of exceeding 40 km/hr. Tractors requiring testing must have their first test 4 years after first registration, and a further test every 2 years after that.
A vital part of roadworthiness testing is an assessment of the tractor’s braking system, and a portable decelerometer, like Bowmonk’s BrakeCheck or BrakeCheck4Quarries, quickly measures the brake efficiency of the fast tractor. The main difference between the 2 units is that BrakeCheck tests the parking brake via a deceleration test, whereas BrakeCheck4Quarries tests the parking brake via a hold-on-incline test.
