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.
