Kubota B6100D & Honda RT5000
I purchased a used Kubota LA302 FEL about a year ago and I finally have had time to work on mounting it on my Kubota B6100 tractor from 1978. The vertical bracket plates and rear axle mounting plates were cut out about a year ago, and just this fall I'm having time to get everything mounted up. Just as mechanics never have time to work on their own cars, as a fabricator, it's hard to find time to build your own toys.

This past fall, my little Kubota finally went kuput! All three cylinders were down on compression, with the rear-most cylinder being all the way down to 200 PSI. The engine's been completely rebuilt now (bored cylinder block, new 1st over pistons & rings, all new bearings, all new gaskets and seals, new glow plugs, all parts thoroughly stripped, cleaned, and primed, and ready to receive a new coat of old Kubota blue paint) and the subframe for the loader is all tack welded together, awaiting a finish welding this evening. Also, as part of this large small project, the radiator was upgraded to a modern aluminum unit (Honda Civic radiator - had to spread the hood by 1", adapt top engine coolant outlet, plumb in lower radiator outlet, and welding a bung for the block heater), so new mounts for that and the hood had to be fabricated.

Things I still need to do include welding up the entire subframe structure (mostly tack welded together), cut out and weld on upper pin hole support plates (makes removable pin hole mounts thicker), clean everything, and paint it. Here are a few pictures of the project so far. I'll post more when I'm to the painting stage.

Looks awesome so far. I too subscribe to the "if the loaders doesn't bolt up, make some brackets" club.....my work doesn't look as good as yours though.

Don't want to steer the thread in a different direction but how did the RT5000 turn out?

Hi Darryl. The RT5000 is still in the shop. The engine's all assembled and installed, but this Kubota took over my time when the parts for the engine rebuild arrived (I waited 3.5 months for all the bits) and I need to get it done and the front of the machine (engine, subframe, and loader subframe) painted before it gets much cooler, as my shop isn't heated. However, remaining work on the RT5000 includes boring the PTO clutch disk hubs (the new crankshaft is a few thousandths larger), replacing two cables, getting a new battery, and firing that pig up. Honestly, I'd love to sell the darn thing now, as I'd love the shop space back, but it doesn't make sense to do so before I can hear and verify that it runs.
