Read articles →A dealership walkaround from Mutton Power Equipment framed as a 4052R vs 4066R comparison, though the sample mostly covers R-series upgrades over the older 4520 line: swivel seat, added fender/console storage, standard work lights, and a demo of EH hitch controls (arming switches, range/parking brake steps, hooking a 3-point implement from outside the cab). It's feature-focused rather than a side-by-side spec or performance breakdown, useful for shoppers wanting to see R-series convenience features explained.
Posted by a dealership channel (Mutton Power Equipment), so expect a sales-oriented feature walkaround rather than independent testing.
Set the range to A or low, set the parking brake, and turn on the EH control switch. Then hit the right switch, wait for the beep, and move the tractor to position the implement.
The swivel seat lets you turn either way to reach hydraulic ports or implements, and makes it easier to get on and off the tractor, unlike the fixed seat on the 4520.
Yes, John Deere increased storage space on the fender and added a small compartment in the middle of the console on the R series.
