I edited my post now that I see how the blades are attached. Sure looks like the center bar had a ton of residual stress from being cold bent to shape. Mild steel would stand it but whatever this is has to be annealed before that much bending. Heat treating can be good, but only AFTER all the...

Sorry to hear about this - especially after all the work you've done on it. I agree with Wolfman - running an HST even for just a few minutes without everything inside being immersed in oil will quickly damage the many polished surfaces it relies on to function. Once they're scratched/scored...

There's a 2-way hydraulic "damper" (like on a screen door) in the linkage, part 110, that assists in centering the drive pedal back to the neutral position. They get worn and lazy and can be easily replaced. But first check that there isn't some brush or cruft under there preventing smooth...

Hope above is useful - take care, Dick B.

Nobody has yet mentioned that your HST's DRIVE BELT could just be worn or loose? HST units usually hold up amazingly well (so do the newer bigger ones). On most Kubota machines the HST is driven directly by the engine but on your TG1860 it is at the back end of the tractor, driven by a belt...

Sorry if this has already been looked at - but symptoms sound like the governor is not responding under load? Find an old tractor mechanic (not necessarily K) to check it out ?

Other side looks ok - its probably fine. The bad side is really pretty bad. Its been running damaged for too long ever to be reliable again. First, welding cast iron is very tricky, usually making its micro-structure even more cracked. It may look ok but it is less strong than unwelded...

Same as on my L5450 - above posts from greensville jay and wolfman show it under the dash panel - I think the harness to it just unplugs.

This may be old news but in 2020 somebody here asked @007kubotaguy whether he had received "that L4150" that he was expecting to get - dunno if he got one or has any steering parts but its worth an ask...... And to Cisco Ranger - no doubt about it - I'm still a major fan of the L3's - Take...

What we're looking for is extra junk in/around the valve bore that could be holding it open. The pressure is high so a tiny metal shaving could be affecting performance. A new valve TD060-59000 costs around $400 so its worth a close look before just replacing one. Below is a screenshot of the...

If you take a look at the machine under the left side you'll recognize the HST unit right behind the engine. That photo is from a part of the shop manual where everything is shown disassembled for clarity - the machine is in pieces - hopefully yours wont need that. The high-pressure relief...

The HP relief valves are shown on WSM pages starting at 3-S89. All you'll be doing is taking them out - with the engine NOT running. When the plug (1) is taken out about 2 or 3 gal of UDT fluid will drain out (have a CLEAN container ready). Here's an excerpt from WSM page 3-S122 showing...

I think you'll find the shaft is not bent - but the bearings on it are in bad shape. Parts 16 and 22in the diagram below. The bearings are industry-standard B6206 common ball bearings - often available at auto parts stores - around $10 each. The oil seal part number was 37650-43490 - now...

When I first got my l48, I took out and interchanged the two high-pressure relief valves, reasoning that the symptom would change from weak reverse to weak forward. It made no difference but that's because the problem was in the cradle bearings. It sounds like your confidence in the dealer is...

Loss of Forward motion but with Reverse still working, MAY not be a disastrous situation. A few years ago I bought an L48 which was ok going forward but was very weak in reverse. There's a long saga starting here about how it was eventually fixed (has been fine now for a long time). The HST in...

At the factory parts website you'll see the L3450 had a lot of optional hydraulic setups. If the machine has a loader its supply and exhaust hoses would connect to the "hydraulic block"(bolted to the frame). That block has a slotted screw head that operates a diverter valve inside, sending...

Looks like the box blade that did all this damage was moving pretty fast when it got jammed. Assuming the pin broke during the incident, forces high enough to cause that much breakage are most likely from tractor mass inertia - like hitting a rock at speed.

Looking close at the above posts about reinforcing brackets, none of them state they fit GCMKCM's L3800. It seems that for those brackets to be designed and available from Kubota "after the fact" is an acknowledgement that these models were not as strong as they should have been in that area...

I think GCMKCM's Post #16 contains some important observations - unusual forces were pushing upward against the hitch, the rockshaft's hydraulic cylinder maybe acting as a post pushing backward, breaking out the top link area? Serious carnage. Maybe there is more to be known about what was...

Here some pics of the broken L4610 posted on TBN back in 2004: Brittle fracture of cast iron fits right back in place. We took out the rockshaft and sealed the rest of it up so the tractor was usable that way until the fix could be scheduled.
