This cylinder looks like a good fit. I would cut off the base end and extend it.

The eyes look right with maybe a bit longer bolt.

The cylinder I used to make my thumb hydraulic was one of their brand and I have bought several others for angling my back blade etc.

Sorry RWS you got this old brain thinking about this again.
The sad part is I found and ordered a new linear actuator last night on Ebay.

Take your pick. I am sure you can find one that will work right out of the box

I guess i'm stuck on the 8" stroke being perfect amount needed and by extending the overall length to fit between the linkage bolts. No need to worry about linkage getting stressed because the cylinder reaches its end of stoke both ways.
That is how I made my non weather proof linear actuator work was by extending the ends. The new one I ordered is supposed to be waterproof 8" stroke and I will reuse my hemi ends. The hemi ends come with adjustable right and left hand collars for mounting to fine tune the length.

I know, here bill goes off topic again,
When I made my thumb hydraulic I found an almost perfect cylinder there. It had side ports with the right pin bores and the rod end was a perfect fit at about 1-1/2 wide.
The base end was narrow so I welded a couple shaft collars on and the machined them down for a good fit.
But also to get the cylinder and thumb to tuck up out of the way I welded a plug in the base end hole and re drilled it a fraction of an inch off the original closed length.
For that I could have cut off the BH77 mount and moved that instead. The re boring made sense at the time.

I wouldn't hesitate to buy the cheaper selector valve. BUT, before you make a decision figure out all your port sizes and make sure adaptors are available to connect the hoses. Consider if you will want 90 degree adaptors or straight. Like I said, the cheaper ones come with #10 SAE ports or 1/2" BSPP. You will probably want to adapt to 1/4" JIC if possible. You're probably going to have at least $300 invested in this project if you go hydraulic.

Any hydraulic setup takes hours of figuring out to make sure all the pieces of the puzzle will fit.

This is why the linear actuator makes more sense in my opinion. The one I linked to in post #34 is IP54 which isn't water proof but should be okay if the tractor is stored in a barn. You could probably put it in a piece of PVC pipe to further protect it. It even comes with the directional switch. You just have to figure out where to mount the switch and get a 5 amp power to it.

Here is the linear actuator I picked up to do the same thing on my MX6000, still figuring out the mounting plates... I just do not have the wherewithall to do hydraulics but my bobcat skid steer has hydraulic QC and I like it, not very fast, likely the same speed as the actuator will be...

Here is a better idea. Go get a hooker to take your mind off doing lazy crap! Will build up your confidence that you can do it all day long! :ROFLMAO:

Thanks all for the advice and the links.

I am going to order the cylinder posted above and the “El Cheapo” 60 dollar diverter…If it craps out I will get a better one….Seems like a small risk in the scheme of things….

Once I get it, I will "fab up" some new handles, or, as I type this I am thinking maybe just modifying the exising ones….still undecided.

However, I know I am going to go the “hydraulic route”

Stay tuned…. 🤞

I think thats a sound plan. I am confident that diverter will be fine - not much in them that can fail.

N.Y,
This one looks simple to make and get ideas from.

I thought about that, but I am impressed with the speed and “beefy’ness” of the hydraulic version. (y)
Hey Coach Scissors, can I come over to your hydraulic team? I put together my new waterproof linear actuator and it is painfully slow. I'm trying to do this from my phone which is also painfully slow for me. My internet is down for the second day but it was working for a while last night and in a weak moment I ordered that 1x8 stroke hydraulic cylinder. Bill

Here is the proof of progress, as is said here often , no pictures, it didn't happen.

yeah, I tried a linear actuator knowing they are slow, though if you buy $$$$ones they are faster, still slower than getting out and moving the handles though. I did get faster speed by using a 'boost convertor' that converts 12 volts to 30..still not fast enough . Hydraulics are easier to get speed...but $$ for 3rd fnx/plumbing.
