From owner discussion and long-term write-ups

What owners say

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

Gathered from owner reports

What owners report

This model arrived recently enough that the discussion around it is mostly about what it displaces, and the answer owners keep giving is the L4802. Several independently argue that the MX does everything better for a small premium and that the L4802 no longer makes sense beside it - one L4802 owner who bought just months before this launched says outright that he wishes he had waited, having moved a number of large round bales with his and concluding he would not want to handle large squares regularly. The technical argument one buyer makes is the most useful version of it: the comparable L is a non-turbo three-cylinder while this is a turbocharged four, so it makes its power while working the engine far less, which he takes as a durability advantage, and he rates the MX three-point as both stronger and easier to adjust. Comfort is the other reason people cross over, and it is not a small one - a six-foot, 250-pound buyer coming off a 65-horsepower utility tractor found the L genuinely uncomfortable, banging his knee on the steering wheel every time he used the pedal and cramping his hip from holding his leg at an angle, while this one gave him ample legroom and a higher view. He bought it mainly for the fit.

Owners who have them are enthusiastic, and specific about what changed. One who traded a 28-horsepower L2800 on eleven acres in Texas says it is emphatically not overkill and simply does not bog down in normal work the way the smaller tractor did. Another on 111 acres bought for snow, clearing and light agricultural work is thankful for two decisions: sizing up to this, and taking the cab rather than the open station, because plowing through a storm at six degrees in nothing but a sweater justified the cost. That cab is around $10,000 though, and another owner weighing the same choice decided he would rather be outside and spend the money on implements. Implement sizing advice is precise: the rule of thumb owners pass around is a foot of brush hog width per five PTO horsepower, and an owner running a 6-foot cutter says it does a good job but needs low range, second or third gear, for clean results in heavy grass.

Two cautions deserve weight against all that. The first is ground pressure, and it comes from someone who loves the machine: he would go smaller if starting again, because after twenty-five straight days of rain he had not moved the tractor since October, sinking three inches anywhere he drove. Being able to pick up a literal ton or a thirty-foot tree is wonderful, he says, and being unable to use the tractor because it rained in the past week is not. The second is the Category II hitch that the spec sheet sells as an advantage. An owner who traded an L2501 for one found his existing Category I cutter and box blade needed sleeve adapters that are not long enough to stay put, and that they seize onto the pins so thoroughly he takes a small sledgehammer to them at every implement change.

What comes up favourably

  • Owners argue independently that it supersedes the L4802 on value, and the most striking version comes from an L4802 owner who bought months before it launched and says he wishes he had waited - citing lift capacity and general capability rather than any fault in his own machine.
  • The engine argument is a genuine one: the comparable L-series 48-horsepower machine is a non-turbo three-cylinder where this is a turbocharged four, so a buyer who compared them reckons it makes its power while working the engine considerably less.
  • The three-point hitch is rated as both stronger and easier to adjust than the L-series equivalent by a buyer who compared the two side by side.
  • It fits larger operators properly. A six-foot, 250-pound buyer found the L-series cramped enough that his knee hit the steering wheel on the pedal and his hip cramped within minutes, while this gave him ample legroom, a higher view and familiar controls.
  • It stops the bogging that sends people shopping in the first place - an owner who traded a 28-horsepower machine on eleven acres says it does not labour in normal work the way the old tractor did, and insists it is not overkill.
  • The cab is worth the money to owners who do winter work: one on 111 acres names taking it as one of his two best decisions, describing plowing through a storm at six degrees wearing only a sweater.
  • It has the power for a mulcher head, which is what pushes buyers up from the smaller L machines - one mulcher owners discuss needs at least 25 horsepower, and this is described as about ideal for it rather than marginal.

What comes up as a complaint

  • Its weight can park it for weeks. An owner who genuinely loves his says he would buy smaller if starting again, because he sinks three inches anywhere he drives after rain and had not moved the tractor in months - being able to carry a ton is no use when the ground will not take the machine.
  • The Category II hitch is a real nuisance with Category I implements. An owner who traded up found the sleeve adapters too short to stay seated on the hitch, and so prone to seizing on the pins that he beats them out with a small sledgehammer every time he changes implements.
  • Two buyers report their salesmen telling them this model's engine is built in a different factory from Kubota's others, in Turkey, and steering them to the MX5400 instead as the flagship for little more money. Treat that as what dealers said rather than established fact, but expect to hear it.
  • A 6-foot brush hog is at the edge rather than comfortable - the owner running one reports needing low range in second or third gear for clean results in heavy grass, and says he would buy slightly narrower next time for the speed.
  • The cab adds around $10,000, which one buyer weighing it decided was better spent on implements given he does not sit on the tractor for eight hours at a stretch.
  • It is enough tractor to change what you tow with. An owner of the closely related MX5400 says his biggest problem became needing to replace his half-ton truck with a three-quarter-ton.
  • The stock toolbox is widely dismissed as useless - one owner fabricated a replacement from a 20mm ammunition can, using the original mounting holes and bracing it against the road-sign bracket to stop it shaking.

Questions worth asking

MX4900 or the L-series 48-horsepower machine?
Owners lean to the MX and give consistent reasons: more lift capacity, a stronger and more easily adjusted three-point, and a turbocharged four-cylinder rather than a non-turbo three, which one buyer reads as the engine working less hard for the same output. Most pointedly, an L4802 owner who bought just before this model appeared says he wishes he had waited. The L's remaining arguments are price, a slightly smaller footprint, and that it is genuinely capable - nobody calls it a bad tractor, only a harder sell at similar money.
Is it too much tractor for five or ten acres?
The size itself is usually fine - owners on eleven and fifteen acres report it being right rather than excessive. The problem is ground pressure. An owner who loves his says he would go smaller if starting over, because after a wet spell he sinks three inches wherever he drives and simply stops using it for weeks at a time. If your ground stays soft or you have no dry season, weigh that above horsepower, and consider that the same owner would have chosen a small skid steer and a mini excavator instead.
Will my Category I implements fit the Category II hitch?
They will, with sleeve adapters, but plan for the annoyance. An owner who came from an L2501 reports the sleeves being too short to stay properly seated on the hitch, and seizing onto the pins so firmly that he uses a small sledgehammer at every implement change. Owners in that position start looking at drilling implements out for Category II pins or fabricating longer sleeves, so if you own a lot of Category I gear, factor this in rather than treating the bigger hitch as a straight upgrade.
What size brush hog should I run?
The rule of thumb owners use is roughly a foot of cutter width per five PTO horsepower, which puts a 6-foot hog about right here. An owner running exactly that, on a gear model, says it does a very good job but that clean results in heavy grass and brush mean low range in second or third gear - slow going. His own conclusion is that a slightly narrower cutter would let him work faster, cutting less per pass but covering ground quicker.
Should I pay for the cab?
It depends entirely on whether you work in winter. An owner on 111 acres who plows snow calls taking the cab one of his two best decisions, describing storm work at six degrees in just a sweater as worth every penny. An owner weighing the same choice put the cab at about $10,000 and decided against it, reasoning that he enjoys being outside and is not on the machine for eight-hour stretches. Plowing and long hours push you towards it; occasional summer work does not.

Summarised from public owner discussion, not from testing. Nothing here was measured by this site, and a report that recurs is not the same as a defect rate.
