Installing Hydraulic Top Link on B21

[RobbieBones]

Thinking about installing one on my B21. Can anyone direct me to a thread dealing with an install on a B21? Honestly spent 4 hours with the search function and found nothing on the B21.

Do you have rear remotes to run the hyd top link ?

If you already have at least one rear remote it's as easy as it gets...either way post if you do or don't and watch this thread for some links to the process...help is on the way...

I have no rear remotes need that info also.

Think you have to get something maybe called Power Beyond kit from your dealer.

There used to be a unit called a HydrauLink that was a self contained hydraulic top link;
goggling HydrauLink toplink shows several links but it looks like the cat 1 units are out of stock.

Otherwise you will need to get a hydraulic source to operate a hydraulic top link.

The B21 is a tlb so you have a great hydraulic supply from the backhoe supply and return. Just need the right valve(s), QDs and hoses. Had that on my B20.
DIY from surpluscenter.com
Does take learning and more skill on your part.
Factory OEM from Kubota is the most expensive but safe option.

Hydraulic top link is an off the self item.

The one you have linked to is a cat 1 top link using a 2" cylinder with an 8" stoke with an overall length of 20 to 28".
Not knowing your tractor , hitch or implement it is hard to say if that is the correct one for your application.
If you are using a manual screw adjustable top link at this time do you know what it's minimum and maximum length is and is it sufficient in adjustability.
You will need a hydraulic control valve and a hose set to operate that cylinder.

If I measured the top link correct, center of pin to center of pin. Longest is 27 5/8 shortest is 17 1/2 is 10"+ stroke, and end to end is 29 3/4 to 19 1/2 for 10.25 stroke. Is 28" cylinder short?? Also won't the cylinder length be ok for any attachment?

I did a DIY top and tilt on my B21.

Excellent work by downsizingnow48. SurplusCenter.com has got plenty of my business. Good specifications and are quick to answer questions. Top quality hoses if you can use them.

Agricenter top link dimensions don’t specify min/max length as center of holes but probably are. Good question to ask them.

The 3pt hitch is bigger on my B26 than my old B20 with higher lift capacity. Pat’s quick hitch also requires longer top link length.
Never cared for turnbuckle sway control or side link adjuster. So if in the fabrication mode make some telescoping sway bars. Together with Pat’s makes changing implements easy.
