    Seized seat rail on MX4800

    I just looked at the Parts Diagram at messicks.com for your tractor, here: Kubota MX4800DT (4WD TRACTOR W/FOLDABLE ROPS) Parts Diagrams (messicks.com) Look under the Hood/Bonnet Category for the Seat Diagram. The configuration of part number 020 in the Seat Diagram (Assy Adjuster, Seat...

    What Government Mandates Save Lives?

    What I love seeing is people driving gray or silver cars around, in the rain, when it's foggy, WITHOUT their headlights on. Brings a wry smile to my face. Um, why would anyone accept those conditions as 'safe'?!?! It's like they're begging for a head-on collision. If nothing else, might save...

    Service Manual 1999 Kubota L2500DT

    Did you get a WSM? I have mine, if you need to know anything specific. Took a close look at your avatar pic. Your L2500 looks to be equipped very similar to mine. What I noticed early on is that, without any implements or weights on the rear end - as your tractor is configured - it is VERY...

    Tractor Sizes over the years

    Yes, and wheelbase is a factor in that. Short wheelbase + heavy implements front and back = lots of 'porpoising'. There's too much weight transfer between the front and rear axles with a too-short wheelbase. -Paul

    General Production Questions......The quest for the holy grail

    Ron, it might be useful to spend some time with the online Parts Diagrams at Messick's and see if you can come up with a model range for tractors that used the same parts you think you might need. For example, when I began thinking that it might be a good idea to squirrel away a spare front...

    Buying a used Kubota

    I have a short list of Kubotas I'd Like to Own (KILOs?). That list is mostly populated by the largest 25-35 year-old L-series tractors. I developed this list by researching the specs, dimensions, and engines at tractordata.com. They have a 'full' listing of Kubota models, here: TractorData.com -...

    Hydroinflation guide (Firestone)

    ...and, here is the fill guide for Rimguard (aka Beet Juice): I note that Rimguard is about 25% more dense than water and CaCl2 is about 10% more dense than Rimguard. I have heard that Rimguard gets pretty nasty smelling, with age... Haven't checked to find local dealers yet... -Paul

    Hydroinflation guide (Firestone)

    Hi Folks, Found this online, in the Firestone Tire Data Book. Here's a link to the Tire Data book: 201341-2020-AG-Databook-combined.pdf (firestone.com) There are tables for about any off-road tire that Firestone sells. Thought it might be a useful reference: Here's a snippet of the...

    Tire Selection, L2500DT

    THANKS for your reply, PoTreeBoy! Front RC is 85.1 inches, not 80.5 inches. But, your calculation is right on. 85.1 * 1.6363 = 139.25" - rear tire RC that 'matches' front tire "measured RC". 139.25"/1.02 = 136.5" - my tractor's ideal "measured RC" for the rear tires, providing 2% front tire...

    regen issues

    Slowly raising hand... For the ONE car I ever owned that had a cat (1985 Chevy Cavalier), at one point, I had to take the tailpipe off, and break up the catalyst using a bar so that it could be removed. The catalyst had come loose and was rolling around inside to frequently plug the cat outlet...

    Service Manual 1999 Kubota L2500DT

    I just bought a reprint WSM for L2500 on eBay for $32, including shipping. Would love to chat with you about your L2500. I think mine is an early build. Rear wheels were date coded 06/97.

    General Production Questions......The quest for the holy grail

    Hi Ron, I can identify with the "overthink" problem! If I were you, I'd just keep my eyes open for a good parts tractor. Watch the auction listings on Equipmentfacts, or the like...Scout out the local equipment auction places in your area. In my very limited experience, one of the weak links in...

    Tire Selection, L2500DT

    The saga continues... I had two choices to make Rolling Circumference correct for the tractor: - replace front wheels/tires with smaller ones - replace rear wheels/tires with larger ones The fronts had recently been replaced, and the rears are half-worn and badly weather-checked. So, setting...

    Save Super UDT2 fluid question

    When I recently drained the UDT from my L2500, it was cloudy, milky in appearance. I think that's what it looks like when water gets into it. It was also brownish in color with stuff that, when you swirl it, looked like suspended fines - dirt or moss? Not metal, though. It's going through the...

    Auction Report: Big old Ls

    I regularly review sales prices of equipment I'm interested in, and there is a LOT of variation that seems to have nothing to do with the condition of the equipment. You can find the photos for the tractors in this sale here: Wolgemuth Auctions - Nov. 25, 2023 Auction | 2 Day Farm &...

    Tire Selection, L2500DT

    Got out and did the Rolling Circumference test today. First, I marked a rear tire and a front tire at the same place (top lug, so I could lean over a fender and see the mark from the driver's seat). Then, I drove a marker stake directly below the rear axle CL. With the 4WD off, I drove forward...

    L2500DT: fixing front wheel drive

    Finished the repair. Cut a 13mm long section from a new prop shaft coupler. Then, TiG welded it to another coupler. This added length to cover unused splines on the front drive pinion. Here's a pic of the welded coupler: You can see how I beveled the ends of the splines in the coupler to ease...

    Auction Report: Big old Ls

    Yesterday was Wolgemuth's annual equipment sale. Probably 500 used (and new) tractors to choose from, in all conditions from salvage to new-in-the-crate. I found THREE big old L-series tractors that were all very interesting to me: 1. L4150 with LA950A loader and L4540A backhoe. 2088 hours...

    Ohhh, THANKS for that hot tip! Here it is: Tractor Wheel Database Somewhere? | OrangeTractorTalks - Everything Kubota GOLD! Deserves a re-up! I will be carrying this list when I'm at sales, simply to judge used tractors on how well the tire ratios (Rolling Circumference or Diameter) match up...
