OMG that 8330 John Deere had a sick sound!! Best sound ever:) These machines are all good. Thanks to the manufacturers All amazing tractors here. To pull another tractor backwards in this situation you need a significant weight advantage. Has nothing to do with power it’s simply weight equals traction. The role of the power is very less in this kind of test. Tractor weight and ground are important. This soft ground is like a brake when the wheels start to dig it
