MX5100

[KYDan]

I let it idle some to put on easy hours, rather than shutting it down when I am doing another short term chore (5-10 minutes typically). I have almost 30 hours on it now so I am getting there. I have not had it above 2400 yet, but probably will ease into that later this week. Peak power is achieved at 2700, but I have not needed to use that yet. I basically have been mining soil from one of my ponds and putting it in piles to compost and dry out. I was rained out this week though and the pond has re-filled some. Usually, September is a dry month, but it is shaping up as a wet one this year. So, I have been reading the manual, shopping for attachments (I need a new rotary cutter and set of lift disc harrows). I did install a toothbar on the loader bucket today and I am anxious to see if I can make a better level cut with it. I am debating about spending a few extra bucks for Super UDT when I change the fluids at 50 hours.

I dont even notice the whine anymore, uh unless you leave the brake on:laughing:

I made a stick on note in flourescent pink and posted it just below the instrument panel. It simply says "BRAKE". I also made another just above the hood release that reads "GRILL FORWARD". I think I am entering the CRS phase of life.

Thanks for the help. The HST is new to me having moved from the syncro-shuttle on my L2900. I have been deliberately operating at lower RPM's during the breakin period on my MX. Also, in high range on my driveway was where I was really noticing the whine. I have had it above 2200 RPM's sparingly and that maybe some of the issue. It has been performing fine. I am not used to the turbocharger whine either as this is the first tractor I have had with this. My diesel truck is turbocharged, but the sound from it is insulated.

I have a L4400, although not as big as an MX5100 their not to far off in HP,no turbo as well. I found my L4400 operates much better above 2000 rpm's. When I'm working it fairly decent, at a minimum I like to be at 23-2400 rpm, it seems to be more in the power band. When your working your tractor or traveling up your driveway, don't be afraid to keep the rpm's up above 2000 and see how she performs. You won't hurt that diesel motor doing that. I think you will find you won't here those noises.

Edited to add: Oh and my tractor doesn't like high gear for anything other than flat ground at top speed.

As I mentioned, there are "diesel guys" (not me, I'm just an average owner, I guess), that say you don't do a diesel engine any favors by running it at or near idle for a long time, brand new or not. The internal operating temperature inside the cylinders does not stay hot enough to burn all the fuel, and the unburned fuel eventually gets down in the rings where it dilutes the lubricating oil and leads to scoring. If you dig back in the old threads here on TBN, there were some extensive discussions of this years ago. Can't say how much of it is "old wives tales", but I've also heard similar things from truckers, who point out big rigs have systems to compensate for this. If someone who knows diesels better than me (there must be a lot of them!), has better advice, I'll listen too!

so glad you are enjoying your MX5100HST,i sure wouldnt take for mine.i cant hear the HSTwhine every1 talks about.but then again im a touch hard hearing from years of loud motors an such.i run my rpms at 1500 to 2000rpms depending on what im doing.my dealer tells me to rev it up pretty good.

Yes, it is a joy, and as I said before I like it better than any tractor I have owned or used. My first Kubota was the L 2900 GST and it was joy and it was my favorite until this one. The HST is seemingly perfect for my uses. A very good friend of mine and a Kubota dealer told me when I was shopping for a new tractor that he wouldn't have bought the HST, but after using one he will never return to standard transmissions. I love seat time in this tractor, it is therapeutic. I haven't done any mowing with it yet, but it should work even better than the 2900. I will have to purchase a larger cutter sometime before next spring. I will probably check them out at the farm machinery show next February.

id go with a 6ft 3pt brushhog cutter or an 8ft brushhogg pulltype shredder.

I plan to use a 3 pt lift type cutter. I am debating about what to use. I have had several budget models, some that performed well and others not so good. I had a 5' Fred Cain behind the 2900 (I still have it, but it is rough and too small behind the wider MX.) I have not ruled anything out yet and I will have fun checking them out at the NFM in Louisville next year. I am sort of leaning towards Landpride. I had their 5' finishing mower, 2572, and it was a good and faithful performer for a long time. I bought a zero turn in 2005 and never used the finishing mower after that. Those things are as great as the MX for their purpose!

Never heard anyone say anything bad about Landpride products. Bush Hog (the brand) and Woods are also good, along with some of the regional brands. We've had a Befco medium duty for 9 years without any problems. As you say, it's hit or miss with some of the economy grade ones.
