We put our John Deere 6030 on Dyno in Cornwall UK and yes we were very surprised with the outcome. This tractor was mechanically restored by our grandson James who is a John Deere technician.
The Legendary John Deere 6030. The 6030 was the most powerful two-wheel drive tractor of its time. ... Consequently, the naturally-aspirated version of the 6030 with 141 horsepower is among the rarest New Generation Tractors with only 45 being built. Cumulatively, 4042 serial numbers were assigned.
