I am new to the forum and fabricator by trade. I had been looking on and off over the last few years for a kit like this but hydraulic..... However I was so amazed that this worked and so I gathered a few misc items and ....... It works like a champ! I have not been able to actually totally install it due to that I am freaking busy. However it tested out perfectly and I wanted to thank you for your input and fore site to even try something like this. I hope to post some pictures in the near future of my 36" tree spade I built about 6 years ago Thanks G

Nice to hear that it all checks out with how you made yours, i never would have thought an actuator like that would have the power either. Mind you, the hydraulic version Bobcat sells does have a relief for the hydraulic cylinder they use to lower it's power quite a lot.

What is the width of the 3/4 flat stock used to make the actuator attachment brackets? I ordered the factory bobtach pins like you said and I found the linear actuator and all its components on amazon. Including all the wiring, switch with relays, flexible liquid tight conduit and connectors came to 240.00 plus 44.15 for the bobtach pins. Now I did get a 100 ft roll of the liquid tight flexible conduit because I'm going to do 2 machines but I'm starting with my T250.

The width is approximately 1-1/2"
I chose the width to match the outside diameter of the sleeve that fits to the actuator. The sleeve was made from 1-1/2" round bar.
Our mustang uses a aftermarket system with a 12 volts hydraulic pump for the quick attach . Yes the bobcat cylinder is expensive almost 800 USD for a.New one

sry to dig up old thread but i'm very intrigued by this, i guess the only issue i see is that you can't use the levers manually, correct?
That's right, once it's fitted, you have to use the button to operate the levers.

I apologize for bringing such an old post back to life but i am in the process of doing this to my bobcat and for the life of me cannot find anywhere to get the weldements mentioned in the post. I have everything else but dont have the skill or machinery to create them. Is there anywhere i might be able to order the two ends for the actuater?

Not that I am aware of.
I am not aware of any standard that specifies the external dimensions for linear actuators. The ends would need to be fit to the actuator you purchased.
Any decent weld/fabrication shop can make them if they had the actuator and access to the Bob-Tach.
"Brilliant!" What a great idea. Thank you so much for sharing. I have been toying with the idea of using an onboard 12v electric air compressor and an air cylinder. However, this appears to be much simpler and more cost effective than any other solution I have seen. I'm sure I have a number of linear actuators in the parts bin. Thank you for sharing. The write up is very professional.

Love the idea. Have a 753 and the 250# actuator. Could you let me know the bobcat parts you bought part numbers? That's all I'm missing here I think. Thanks very much!!

On mine the part number is 6731119 - PIVOT, WEDGE, 50 mm (1.95") long pin.
The Pivot Wedge can be bought with the short .75" long pin or the long pin version for the Power Bob-Tach.
You can look up the Part Number for your loader at https://www.bobcatpartsonline.com
Enter your model number or serial number and open the BOB-TACH parts list.

TriHonu this is probably a stupid question but I looked up these 6731119 - PIVOT, WEDGE, 50 mm (1.95") long pin. and for the life of me can't figure out where they go and why they need them. Also do you have to set it up so the actuator piston fully closes when in that position or will it just stop when it is in the fully open position ?

The part is the pivot that the handle moves to slide the wedge pins.
The longer pin extends through the handle so you can connect the actuator on top of the handle. The longer pin goes through the handle, the gold colored bushing and then through the flat plate attached to the end of the actuator.
If you page back to the pictures, you will see that I have my actuator set up so it is almost fully retracted when the handles are in the open position. This was required because of the length of the actuator I used.
The actuator I used did not have built-in limit switches so you have to let go of the button as handle approaches fully open or closed.
