Front loader for a B7200

[Paul Allwood]

If you haven't made your SSQA yet, you could consider instead doing the older proprietary Kubota quick attach. I only say this since it seems like all the implements you're going to use you're going to fabricate anyway. The Kubota quick attach is quite a bit lighter than an SSQA setup. I ended up putting one on my B2601 since in New Zealand basically nobody has SSQA, and I would have had to special order it. It was just as easy to order the older quick attach, and it meant I didn't have to modify my bucket.

Thanks Paul. You're right, I'll probably make the implements I'm going to use initially, at least for now. I hadn't considered the older style, and chose to make the SSQA style so that it is compatible with other things here in Australia if I do need to buy something, or even borrow an attachment from a friend. I'm also a bit far down the track to change now.

PS - I used to model things like this in Solidworks which takes out a good bit of the guesswork..... I've now resorted to hand sketches and plywood or cardboard models, which often means more grinding and re-welding later, but it's the best I can do.

Hello Paul,

I use Visio (or LibreDraw) for planning geometries. Not as powerful as Solidworks but faster than making cardboard or plywood templates. You can group parts and rotate them around pivoting points, so easy to check angles and if you hit something I find it very useful.

Also this web site is handy to calculate deflection of steel sections, so you get an idea what is required so that you can keep the weight down: Link steel calculator

If this is as far back as you can get the cylinder to go, it's very likely that there is a stop inside the cylinder that needs to be removed.

What bore and stoke is the cylinder?

View attachment 160976

It's 2.5" bore x 8" stroke. This model of cylinder does use an internal stop, without it it's the same as a 10" stroke cylinder. I can only assume they do it so they have more common parts in manufacturing.

So with the internal stop in place, it still gives a stroke of 8" (LA344 spec is 7.7"). The stop can stay where it is - this is the stroke I want to match the LA344.
