Probably about time I updated this thread. I've been doing a lot of work on this machine since the last post here. The hose brackets were completed and worked out well, I was able to route all the hydraulic hoses clear of moving parts and hold them neatly.
I've been putting a lot of time into the linkages and pins for the curl mechanism. I turned bushes from 4140 for all the pivot points and case hardened them using my foundry furnace. I had made everything in imperial sizes, 1 1/4" pins for the main pivots and 1" for the other linkages as that was the size of the clevis on the rams I bought. I didn't consider the difficulty of obtaining material in those sizes, had to order some imperial shaft from an eBay seller and trust that it is what he says. I read that bareco use 4140 s/h for their pins so that is what I went with. the intent is that the pins are the wear item, as they are the easiest component to replace. I bored and cross-drilled the pins for grease passageways.
I've been having second thoughts about the style of quick-hitch bucket attachment, I don't like the fact that the JD attachment puts load through a pair of lynch pins, it's probably fine on a sub-compact tractor (or not, they did not keep this arrangement in production for more than a couple of years), the arms of my loader are also spaced just a tad too wide for it. I have plans to install a 'Euro Hitch' which is much heavier duty. But, I have a biggish drainage project that has to be completed over summer so I decided to set things up with the JD hitch as it is very simple to build and my bucket already has the system in place.
I put together a fairly crude version of the JD hitch and welded it to the front of the new linkages. Finally got the thing completed this afternoon after a marathon effort over the last week or so.
I'll use it for a while before stripping it down and taking it to the sandblaster and then painting it to match the rest of the tractor. Be a shame to ruin a new paint job if anything requires changing.
I'm super happy with the result so far. The double linkage provides a massive amount of extra rotation to the bucket, I haven't measured yet but I think it has about 220 degrees of rotation where it previously had about 160. In it's old guise, it would not curl back enough with the bucket down low, which meant I was travelling with the arms raised in order to keep stuff in the bucket; then it would not curl forward enough to empty the bucket cleanly at full lift. Better now:
I can potter away at building the Euro Hitch once the current dirt projects are under control. Been looking at 'grapple' attachments too, I have a lot of tree work that a grapple would be just the ticket for. The prices here are astronomical though so I'll probably have to build that too.
