QA backhoe
 

as some of you may know, i have a 1772 with a KW loader and backhoe. i was thinking it would be nice if i could take this backhoe off when im not using it without spending 2 hours unbolting 8 fasteners, disconnecting 4 hoses and then blocking it all up. i came up with this quick attach mounting set up. i like how the Kubota QA worked, so i took some ideas from that. i actually had 80% of the materials on hand, so that helped out the wallet. the only parts i had to buy were the hydraulic quick connects and 2 clevis mounts. the bottom of the mount sits in 2 "J" hooks and the top mounts with 2 3/4" pins. it was a bit tricky to get everything lined up so the pins would just slide right in without a hammer. lots of tack welding, testing, and grinding. took me the whole month of January but finally i got it. here's a few pix of the fab work and a video demo of the QA setup.

Cool set up :beerchug:

Sweet setup and real good shots of your work on your video!! You've done some really smart fabrication there.

Cub Cadet 123

cool idea only thing I change is I make tapered pins to make lineup alittle easier

Top notch work, and great vid, Ken!

Very cool setup!:beer2:

thanks!

yes, tapered pins would help. i might just take the pins i had and put them on the lathe and taper the ends down. good idea! thanks.

Slick!! That makes things alot easier. Nice work.

Looks good!! Need a few vids of that thing doin work!

i can make a video of it working. might have to wait till all this snow is gone so i can find the dirt again.

I hoping to get to build my backhoe this year have PF engineering's plans I already have a kwikway loader but see if the money comes though

Ken what size is your rear tires?

Good job Ken!! My only question, what took you so long to get it set up like that! LOL! I'll say it again, GOOD JOB!

Question:
Where did you get, or what model/brand of backhoe is that?
Also, are you running a PTO driven hydraulic pump, and where is the reservoir?

Nicely done! I like it. But rather than tapering the pins, which would give you a loose fit and potentially a wear issue, I'd weld locating angled tabs on the arms, so that the BH's rings would settle into a "corner" of the angled tabs at just the right location to achieve alignment. That's actually how the QA works on my Kubota BX23 loader. The kubota's QA on the BH has a more complicated arrangement for the upper pins.

I think he meant just putting a taper on the end, so it wouldn't be so hard to start the pin into the hole. :beerchug:

rear tires are the OEM size for the supers 26x12-12 i have Carlise tru powers

the backhoe is a Value leader brand. its suppose to be a CAT 1 pto drive. but i modified it to make it work for me.

the hydraulics run off the kwik-way loader pump and the reservoir is in the uprights of the loader.
