A highlighted cell wins its row on the rule named above the table: more power, lift, capacity or flow, or a lower price. A lift row is left unwon whenever the two makers measured in different places, or where either of them did not say — a figure quoted at the pivot pin and one quoted 500 mm ahead of it describe the same loader and differ by roughly a third, so ranking them against each other would invent a result. Prices are typical list and move with dealer packages.
From owner discussion and long-term write-ups
What owners of each one say
John Deere 4066M
What they like
- 54.2 PTO hp with the PowrReverser is more than any 4R except the 4075R, and it drives a 7 ft cutter or a small round baler without complaint
- Charge-air cooling is what separates the 4TNV86CHT here from the 4052M's 4TNV86CT, and it is worth 14 horsepower on identical displacement
- At 3,982 lb it is 228 lb heavier than a 4052M, which is useful ballast at the back of a loaded 400E
- 17.4 gpm total flow and a mechanical rear differential lock as standard
- 12F/12R PowrReverser is base equipment rather than an option
What they complain about
- No cab is available on any 4M - the ComfortGard cab belongs to the 4R line, and dealer pages that show a cab fuel tank or a cab weight for this model are reproducing a shared 4M/4R spec table
- The 400E loader and the 2,500 lb hitch are identical to the 4052M's despite 14 more horsepower, so nothing about what the machine can lift changes
- 1,764 lb at 500 mm ahead of the pivot pin is the number to plan a pallet-fork job around
- Deere sells a separate 4066M Heavy Duty with the 440R loader, a Category 1 and 2 hitch and a 3,130 lb lift at the link ends, listed roughly $17,000 above this machine
- Cruise control arrives only with the optional eHydro, which also costs 2.3 PTO horsepower
John Deere 4052R
What they like
- Mechanical self-levelling on the 440R keeps a loaded pallet flat through the lift, which matters more than raw capacity on fork work
- A premium ComfortGard cab with heat and air conditioning is a factory option; the equivalent 4052M cannot be ordered with one
- 17.4 gpm total, 11.2 gpm implement and a separate 6.2 gpm steering circuit
- eHydro is standard with cruise control, and the 12F/12R PowrReverser remains available for 1.7 more PTO horsepower
- Turning radius of 9.19 ft with brakes keeps a 3,770 lb machine usable in a yard
What they complain about
- 39.1 PTO hp with eHydro is 1.7 hp less than the cheaper 4052M delivers through its standard PowrReverser
- Deere's published maximum-height 440R figures are internally inconsistent, printing the 500 mm-ahead capacity above the pivot-pin capacity; the 1,500 mm row is the one that reads correctly
- The cab build drops fuel from 15 gal to 13.8 gal and adds 905 lb
- Dealer sheets split on whether this engine is rated 50.8 or 51.5 hp gross; the stated 37.9 kW converts to 50.8, which is the figure used here
- A diesel particulate filter and oxidation catalyst are part of the package, with regeneration cycles to match
