He managed to drive for five miles before passing out.
The drunk man in question is 39-year-old Marcin Pietrowski. He was arrested by police in Janow.
Officers found him fast asleep in a ditch beside a dirt road leading to his farm.
A police spokesperson said: "We had lots of calls from other drivers saying he could barely steer the vehicle.
"When we got there, he'd stopped the tractor and had fallen out of the cab where he passed out."
Pietrowski, now facing a large fine or jail time, said: "I'd had a few and needed to get home, but I'd completely forgotten there were only three wheels on that tractor."
