  • A very old and fully restored Marlow diaphragm pump.
  • This fully operable 1942 Manitowoc 3500 crawler crane represents the first use of a torque converter in an excavator. The 3500 was also the basis for the very successful 3900.
  • When delivered to the Museum in October, 2013, this 1976 Mack DM68SSX tandem axle dump truck was our youngest machine.
  • c. 1963 Clark Michigan 175A Series I wheel loader. This machine is the Museum's garden tractor, snowplow and general workhorse. Bucket capacity is 2.25 cubic yards.
  • 1953 Clark Michigan 75A wheel loader. This was the first production unit of what was, at the time, the world’s most advanced rubber-tired loader line.
  • Circa 1950 M. R. S. 150 AGT wheel tractor. MRS tractors were developed in the 1940s to pull large scrapers and bottom dump wagons. The large fenders can be filled with ballast for greater traction.
  • 1933 McCormick-Deering TA40 crawler tractor. The crawlers and undercarriage are all original; for its entire working life, it powered a sawmill from the rear power take-off.
  • 1934 Michigan Power Shovel T6D truck crane. Michigan was the first crane manufacturer to design its own carriers for truck cranes. Lifting capacity was 6 tons.
  • 1926 Marion Steam Shovel Company Model 21 electric shovel, the smallest shovel to be powered entirely by electricity. The power cable is on the ground behind it.
  • 1950 Michigan Power Shovel C16 shovel.
