Read articles →A dealer walkaround at James River Equipment where the owner trades his 4066R for a 4075R, with a dealership rep walking through the specific differences: the larger intercooler and intake, horsepower gain (9.6 hp, 8.1 PTO hp), rear lift capacity increase (209 lbs), HD front axle trade-offs, fuel tank size, and upgraded electronic hydraulics. Best for 4066R owners weighing the step up to the 4075R.
The creator appears to be a turf and grounds care business owner documenting his own equipment purchase, with the walkaround conducted alongside staff at the selling dealership.
The 4075R puts out about 9.6 more horsepower than the 4066R, plus 8.1 more PTO horsepower, with 151 pounds of torque, a 19.9 pound boost over the 4066R.
Yes, slightly. It goes from 3 meters turning without brakes to 3.2 meters, a small tradeoff for the added rear lift capacity and axle durability.
The 4066R used mechanical lever hydraulics with separate controls, while the 4075R has electronic hydraulics combining up, down, and hitch assist into one control pad.
The 4075R has about 209 more pounds of rear lift capacity than the 4066R, due to how the tractor is configured and its hydraulics.
