Just recently picked up a Koyker 80 loader for my 186D, (from a heads up posted on here

(Thanks Winston!)
I've read and heard numerous examples of breaking small tractors in half at the bell housing while using a loader, so figured now would be the time to build a subframe of some kind to prevent that nightmare.
Spent some time evaluating a few possible ways of going about it, but wondered if anyone here has built one for a loader on a 186d (or 1510d, 1610d, etc)
I found Ducttape's excellent thread about building a subframe for a backhoe for a 186D:
http://www.tractorbynet.com/forums/build-yourself/105478-backhoe-subframe-my-25-yr.html
but I don't need a backhoe version, just a simpler version to avoid the bell housing breakage.
The most common idea seems to be to add new steel members that attach to the loader mounts beneath the posts of the loader (these mounts are bolted to the frame rails under the engine) and the new steel members then run from there back to the rear axle. Designing a pair like this from 2"x4" steel rectangular tube seems doable. Might be the easiest option I can envision. But I was also thinking about trying to adapt a couple of 6-8" tall plates of steel that could run right near the edge of the bell housing and along the central cast iron transmission column, and bolt onto the front part of the rear end casting. This might give more strength due to the geometry, but be a bit harder to shoehorn into position, and would require drilling and tapping what appear to be a couple of blank bosses in the rear end casting.
Anyway, if someone has a loader subframe on their Yanmar, i'd love to see pictures or hear about how it's designed.
Otherwise, I'd also appreciate any ideas on the best way to design one.
