Deutz Fahr is phasing out their air-cooled tractor
I was speaking to the U.S. importer for Deutz-Fahr tractors and he told me they will be phasing out the importation of tractors with Deutz air-cooled engines.
This is due to emission and noise regulations coming into effect for tractors. The air-cooled engine doesn't do well.
They will still import the tractors with Deutz liquid cooled engines. Here's a link to some info on their tractors:
They seem to have good specs. If you want an air-cooled Deutz there are still some in the pipeline and in the USA for sale but not for long.
