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

Kubota M5660SU

What they like

  • 3,307 lb of lift 24 in behind the lift points for $34,093 - the same hitch rating Kubota quotes on the $65,612 M4D-071
  • 50 PTO hp from a 58.7 hp engine, with a fully synchronized four-speed and a hydraulic shuttle for direction changes
  • 17.7 gal tank on a 4,387 lb tractor gives a long working day for the class
  • Category I and II hitch with telescopic lower links, so large implements hook up without a second person
  • At 4,387 lb in 4WD ROPS form it is a genuinely light utility tractor, which keeps it useful on soft or sloping ground

What they complain about

  • The $34,093 figure is the 2WD SUH; the 4WD SUHD costs more, so price the drive you need rather than the headline
  • No cab is offered at any price on the SU, unlike the M6060 and M7060 that sit above it
  • 10.6 gpm is the lowest pump output in the M60 range, so loader cycles are slower than on the M6060
  • Analogue instrument panel, no tilt steering and a semi-flat deck - the specification is visibly cut to hit the price
  • Kubota's own literature quotes this engine as both 58.7 hp gross and 57.9 hp depending on which page you read

Kubota MX4900

What they like

  • 41.3 PTO hp from a 50.3 hp engine is a high conversion rate for this class, and enough for a six-foot rotary cutter without stalling
  • The LA1065 loader lifts 2,275 lb at the pivot pin at full height and 2,864 lb at 1,500 mm, so it carries more the lower it works
  • 8F/8R with a synchronized shuttle means direction changes on loader work do not need the range lever
  • Same 2,310 lb three-point lift at 24 in behind the lift points as the MX5400 and MX6000, so implement choice is not limited by being the smallest model
  • Category I and II hitch on a tractor under $34,000 opens up implements the compact L range cannot hang
  • Factory cab is offered, which puts a heated and air-conditioned utility tractor within reach without moving to the M range

What they complain about

  • Costs $4,626 more than a base MX5400, because the MX5400 is quoted as a 2WD and the MX4900 is 4WD only - the cheaper tractor on the price list is the bigger one
  • 50.3 hp is the least power in the series for a chassis that weighs the same 3,716 lb as the 55.5 hp MX5400
  • Hydrostatic costs extra and changes the rating to 51.8 hp, so the headline figure on the price list is the gear model's
  • 13.5 gal in ROPS form drops to 11.9 gal when the cab is fitted, which is a real cut to working time on a machine bought for long jobs
  • No cruise control, no creeper, and the partially synchronized main gearbox only synchronizes 3rd and 4th
