3pt hitch Hydraulic top link and control

[joea99]

Got a Kubota B21 with WR Long 4 in 1 bucket, with the control valve up front. I don't think this is a Kubota specific question.

I just bought a 54 inch Woods Box Blade (scraper they call it) and was thinking I should spring for a hydraulic top link. I guess I am feeling my age.

Looks like all I really need to do is get the correct length range Cat 1 top link and add hoses and a control valve. There are a couple shops around (NAPA and Parker) that can make up hoses for me.

I have a handle on hydraulics basics, changed hoses, filters, etc, and have some recollection of terms from my navy days (from required cross training, not my specialty) but do not know much of the current terminology to quickly figure out what I need.

Question regards the control valve. I'm hoping to find something that I can slip into the hydraulic line, either to the front bucket or the hitch raiser/putter downer, and when idle, with just allow flow though it as if it were not there. I figure, maybe wrongly, that since I am not going to be using all of those at the same time, that could work fine.

Got any good words.

Umm, well. I just woke up and realized I will have the backhoe removed, so, the hoses will be right there, I guess I can use them rather than do a Rube Goldberg setup.

Yes, just insert your valve where your backhoe would go. If two hoses for the backhoe, you need to find a place for the tank line to go. I teed into my loader valve tank return.

I may not be able to do that after all. On this model there is a lever, pull up for 3pt, down for backhoe. I'll need to check the hydraulics diagram to see if that shuts off flow to the backhoe hoses. I suspect it diverts it completely.

The ugly, but cheap, solution is to use your 4 in 1 lines.

I'm all for cheap, as long as it works.

You're thinking of just putting it a diverter valve, hoses and quick connects?

Doesn't Kubota make a rear remote kit for this tractor? A rear remote is ideal for controlling a hydraulic top link.
The factory remotes usually integrate better into the machine and are more ergonomic than home made. But it's possible to do your own as well. Put it in series between the loader valve and the selector for 3pt/BH.

If so, I would surely consider one. If someone knows the Kubota numbers I would appreciate it. I'll search for them now on my own. I would not expect any dealers to know, given the age of the unit.

And sure enough, searching with the correct terms (top and tilt kit) finds B8032 as the kit part number. Looking at Messicks parts list it is one pricey set of toys.

Astonished to find it is still listed and under $800. I tend to think I would be better off getting that than piecing together on my own.

Problem still remains (assuming it really is still available) I need to hook it into the hydraulics some where. The matching Kubota kit with valves, etc, is B8042 and is no where to be found. If someone can describe it and where it plumbs in, I can maybe scrounge up parts one by one.
