According to figures released by the AEA, bottlenecks in global supply chains are increasingly affecting the farm equipment sector.
In November, only 543 agricultural tractors were registered, 16% fewer than in the same month last year and 14% below the average for the time of year.
Stephen Howarth, agricultural economist at the AEA said, "This is only the second time in the last 12 months that registrations have fallen below the level of a year before and comes despite all reports suggesting demand remains very strong.
"Even with the recent slowdown, registrations for the year to date are still 16% up on the equivalent period of 2020 and, indeed, they are already 7% higher than the total for the whole of last year."
