Most plows/ploughs pulled

The most plow blades pulled by a single tractor is 50, achieved at the James Valley Threshing Show in Andover, South Dakota, USA, on 11 September 2022. This massive plow was made by joining five historic 10-bottom John Deere gang plows, each with five operators, and it was pulled by the 150-hp Case, a reproduction steam-powered traction engine built by Kory Anderson (USA).

The 150-hp Case (the largest steam tractor ever buit) generates an astonishing 5,000 lb-ft (6779 Newton-metres) of torque, allowing it to exert the massive amount of force required to pull so many plows through the Earth. By contrast, a modern tractor-trailer (semi-truck) generates around 1,500 ft-lb of torque.
