Farmers are now able to operate half tracked rubber tracked tractors on public roads without a permit following recent amendments to the National Class 1 Agricultural Vehicle and Combination Mass and Dimension Exemption Notice 2019.
The NHVR undertook engineering assessments and consultation on the infrastructure impacts of these vehicles, which showed they imposed no greater risk than the vehicles already allowed by the Notice.
State and territory road transport authorities agreed to their inclusion in the Notice.
Summary information for rubber tracked tractors can be found in the National Class 1 Agricultural Vehicle and Combination Mass and Dimension Exemption Notice Operator’s Guide (pages 10 and 11).
Examples of the three types of eligible rubber tracked tractors are:
- one pair of tracks and no conventional wheeled axle (dual tracked tractor)
- two pairs of tracks and no conventional wheeled axle, (quad tracked tractor)
- one pair of tracks and one conventional wheeled axle (half tracked tractor).
The Notice and Operator’s Guide lists mass and dimension limits are published on the NHVR website.
