Overview
A side-by-side comparison of the 4066M and 4066R parked together, walking through both similarities and differences feature by feature. Covers base weight, loader capacities, cab vs. open-station options, and a detailed list of 4R-only extras: suspension seat, tilt steering, cruise control, motion/load/speed match, factory third-function hydraulics, and quick-adjust sway arms. Goes reasonably deep on practical tradeoffs. Best for shoppers deciding whether the 4R's premium features justify the price difference.
Good Works Tractors is a tractor and attachment dealer that also sells and finances equipment, so the walkaround carries a sales-oriented perspective alongside the practical comparisons.
