Two Kerry County Councillors are appealing to the RSA and the Transport Minister to reconsider the implementation of NCTs for tractors.
Cllrs Dan McCarthy and Johnny Healy Rae raised the matter at a meeting of Kerry County Council.
The Road Safety Authority is working on legislation to introduce mandatory road-worthiness testing of tractors capable of driving more than 40kms per hour by May 2018.
The RSA says testing will be required for tractors mainly used for hauling for hire or reward or on the owner’s “own account”.
Agricultural contractors cutting silage and transporting it to a silage pit is not considered to be commercial road haulage.
Tractors with no tests will face incurring five penalty points and a €3,000 fine.
There is no figure for cost of testing available currently.
