Aumann Auction --On-site & Online Bidding

Jun 22, 2019 17766 Eddyville Road Ottumwa, IA

Mike Verhulst grew up on a Minneapolis Moline farm and worked for Minneapolis Moline and White from 1968 until 1974. Mike worked in Hopkins in the engineering department on the G900 & G1000 in the beginning. He later worked on the 50 series improvements. In early 1969 on a fateful trip to the Arizona test farm with the head of engineering, Mike began developing the A4T articulated four wheel drive concept. He was later heavily involved in the development of the White 4-150. He also was involved and did a lot of work on the legendary Corporate Tractor in 1970.



White 4-150 Four Wheel Drive Prototype, never sold but given to Mike from the White Engineering Department around 1975 or so. Mike took the tractor home and put it in the field! The tractor has several features that were not included in later production tractors. Experimental part numbers like rear casting #X80-81055857 and front casting #X30-3105865. Many unique features and one off parts.
