Questions on MX machines

[big bubba]

I bought a Mx5200 & find it has plenty of power

Reason I went 5200 & not 5800 is I assumed same engine stressed less will last longer

This coming from a guy who has always bought largest in a series with all bells & whistles

Don’t miss anything

absolutely. MX series is a great link between L & M. never questioned that. just that using MX for a 10' drag cutter as OP is intending is an inadequate match imho. my previous MX5000 did just fine w/a 6' hd rotary cutter, probably a 7' one too (3ph) though i'd never consider a 7' hog.
the MX may handle a 8' drag rotary cutter (twin spindle), don't know much about those.
my own 3ph 8' twin is a perfect match for my machine.

your MX is a versatile tool, am sure you'll be pleased best regards

I love my various Kubota Non-Turbo engines. I have never thought, gee, I wish I had more HP. Just another thing that can't go wrong if it's not there.

I was always taught to buy the lowest offering in the better line. Like, buy a stripped down CADDY, rather than a loaded up Chev. Or a basic JD 6000 rather than a loaded up 5000. More of your money is going for quality rather than gimmicks. It has served me well.

On the topic of lubrication: turbocharger is not lubricated by diesel. You are confused by the issue of low-sulfur ULSD in the high pressure fuel pumps of older diesels which were not designed for ULSD. Many advocate aftermarket diesel fuel additives with lubricants for those older engines.

In a modern diesel the turbocharger and EGR are critical components for maintaining combustion in the range of minimal emissions. Direct injection allows timing of the fuel and start of combustion, waiting until the fuel is useful. Results in much quieter engines.

Nowadays you had best be careful thinking what you think you know. There is a large fuel cooler under my Duramax Bed, used to cool the electric injectors. It's so wrong in my opinion. Like a Diesel Engine on Life support.

I sometimes toy with getting an M series without loader. That M/MX thing is most confusing. They keep throwing around words like "Utility" as if that is supposed to tell me exactly what it is, not what they happen to call it. I almost get the impression, the M is a real tractor and the MX is a light consumer offering, but they don't come out and say that.

"the M is a real tractor and the MX is a light consumer offering" that's a novel idea

There is heating when one compresses fuel to 30,000 PSI. Is liquid so it doesn't compress much but a lot of work was exerted getting that pressure.

The M for Ag, day to day hard use and the MX for occassional "UTILITY" use is EXACTLY what Kubota is telling me on their site.

That wasn't the interpretation I had put on Ag v's utility. To me a utility tractor was a tractor that can do lots of smaller and odd jobs. Drive a loader, drive a cutter, do some ground engaging work. But not big enough for serious agriculture - so to me that was a size and capacity thing, not a durability thing. I guess we all have our own interpretation. As someone more in the compact tractor space, the MX looks like a step up to a real tractor. I guess if you're in the M class world, then the MX might look like a step down to a toy tractor. Context is everything.

Thanks everyone for the feedback. I did talk with a buddy who said with what I'm wanting to do and cut that a 58 hp tractor with an 8' cutter will be fine. He cuts landfills with a 120 hp New Holland and Bush Hog 4815 batwing mower. He does use an 8' cutter to trim around the well heads. So worse case I can try one out in the off season (he cuts the landfills twice a year).

More than likely I will stay with my current cutter for awhile and look for a slightly used model. Do these tractors pressurize the fuel like current diesel trucks? Think I need to do some more research on diesels/turbos, because I think the only thing I know about a turbo is what I hear and how to spell turbo.

So a MX is what I'm going with mainly due to it being the largest tractor I can get with an HST. The mower will be the biggest hp challenge. I'm excited, just need to look at the numbers on which MX to buy and learn about turbos and reliability. In reality it would be the MX4800 or MX5800. Yes I will fill the tires and probably use rear weights as well (wheels set to widest due to Ozark terrain). I have a friend with 30 acres that wants my L2501 (he currently has an old Ford gas tractor). Need to build a barn at the land, because the bigger tractor can't fit at home anymore. Going to grade out an area this weekend with the L2501 (filled tires and EA Extreme Box Blade 78 inch). I've already graded out one area, but the wife wanted it moved a bit, lol.


You guys have been great, the varied real world feedback is what makes this place good IMHO.

Diesels simply run better with a turbocharger. The turbocharger gives the ECU options to better control the operation to better produce HP with less fuel and less smoke.

High pressure fuel pump is necessary to direct-inject fuel in the combustion chamber when the air is compressed. This allows the ECU to control when the combustion starts same as ignition timing on a gasoline engine. But it seems to be more than that because on diesel they will often use multiple short bursts of fuel perhaps for a longer slower burn?

In short, "Insert fuel here, then magic occurs. Don't worry about it."
