On the B7510 parked in front of me now, I observe that the stops (that I highlighted green above) allow the user to easily put the hydraulic control lever in a position to reduce the UP and DOWN speed. They have no effect whatsoever on the height, just the amount of time it takes the implement...

On the B7510, the stops I show above (highlighted green) control only the speed. The implement lower height limit is controlled by the 'locker' on the rod under the seat:

The B7510 in my shed is new to me and before buying it, I had a B7100 (the early variant) for 30 years. That B7100 is definitely the type of 'tool' that has become just an extension of my body. I never looked into 'position control' as Kubota calls their more modern control. I spent a lot of...

Yes. I made a couple of 5/8"stainless pins and steel brackets out of 3x3x.25 angle iron, and popped 5/8" and 3/8" holes in them. The 5/8 hole will clear the 14mm bolt already present in the ROPS: And the 3/8" holes accommodate bolts into the threaded holes on the bottom of the pins: The...

Like pretty much everyone with a tractor, I want some onboard tool storage. Something big enough for a chain, a few random tools, hammer, adjustable wrench, maybe my 16" chainsaw, can of gas, etc. I have a 28 x 15 x 5" 'tray' fixed to the hood of my old b7100, and it worked out surprisingly...

My recent experience was that a used B7510 was 40% of what a new equivalent one lists for. Obviously 'used' encompasses a very wide gamut. I found an 18 year old B, with 1k hours in what seems to be very good, well-maintained condition, from an owner selling for the 'right' reason (downsizing...

Thanks guys for the tips and cautions. Appreciate the feedback. (we all know the dopamine hit is the reason we keep coming back) The cross-drill-the-pins idea is spot on. Once a guy has a lathe sitting in the corner of the shop, it seems like it becomes the hammer and most problems...

Pretty much wrapped this project up. Here's the latch plates on the tractor: The modified bucket: And both of them together: I don't think I'd change too much, although I wished I'd have spent some time practicing my welding before tackling this - it's been a while since I did much MIG...

I like this design, and am planning to do something similar. Now that you've been using it for a few years, would you change anything? I don't see a way to lock the forks in position - is that ever needed?

Todays update - I'm finished hacking up the bucket with the angle grinder. I had to cut back the reinforcing brace a bit: Then put a cutout in the bottom 'lip' piece to accommodate the SSQA pin. It's 1/4 x 3" stock. And here's the bucket with the bottom lip plate and reinforcement plates...

That's a very good point, and I'll plan on some simple feature to keep the chain centered.

I had to take a statics class and was crap at it. I managed to avoid dynamics. So I have a little understanding of this type of mechanical design. I've read the LA302 manual, and understand the diagrams showing lifting force limitations, at least to a first degree. My intended use case...

Thanks for your concern - I hope you decide teach us the other forces you have in mind. I supposed we were all here to share and learn.

I did some analysis on the deflection of this beam, leaded to 2000 pounds at the center (worst case), it only deflects about .060". I'm not seeing the problem...

Here's a pair of bucket ears out of 4 x 3/16 stock: Stuck them onto the bucket: Tacked on a 2x2x3/16 angle iron lifty thinger between them and a quick fit test: Next - adding a little structural reinforcement to the above, finishing the welding, and then on to the bottom 30 degree 'catch...

Not 100% sure yet. I want to keep from adding unnecessary weight, but also want to be able to use this link (the cross member between the two latch adapters) to throw a lifting chain over and lift to the capacity of the loader arms. It looks to me like 2x3x3/16 rectangular tubing would be fine...

Yes - the model I show is a 6" grinder. HF furnishes it with a 4-1/2", 5", and 6" guard, so you can use it with any of those size wheels. I used 6" cutoff wheels - worked great!

I went ahead and cut the 4 brackets that'll get welded to the latch plate. They are cut from 4 x 1/4" stock. The critical dimensions to the hole positions. The angles are all 30 or 60 degrees. Drilled a pair of 1" holes in each to accommodate the pin bushings I showed above: Then I...

Curious why this is needed. Is there a reason that Kubota's procedure (basically shut off the engine, and push the hydraulic control lever through all its positions) doesn't work? I've had no issues.

The deed is done - glad that part is over! My bucket now has flat mounting surfaces on the back to accommodate whatever adapter plate I need to put there. I want to be sure I understand the concern here - Is it that once the bucket is attached and the loader arms are lowered so the bucket...
