Modifications to Yanmar 2010D

[Calpyro]

Scotty,
I do plan on adding supports from the transmission bracket to the rear-end where the drawbar is attached. Partly to add support for the loader and partly for skid protection. I seem to get the tractor stuck in the mud frequently and I am concerned about bending the many linkages under the tractor.

Brent,
I only could find two of the mounting holes on the clutch housing. I looked at a Bush Hog loader which utilized some of the locations in the frame as a prototype for my mounting plates. I am trying to spread the stress of the loader over a large area to minimize the possibility of breaking things. I may be overbuilding it a bit but steel is pretty cheap.

Good idea. Not only is it steel cheap, but also nicely heavy. Below the axles and between the wheels it would be hard to add too much steel

My 1920 does.

"Sure do like those Ford seats. I remember one that had sliders for different heights and seating position. Is it one of those? "

Well, I got a chance to work on the tractor again. I had to reroute the steering linkage and do some trimming of the mounting brackets. While the steering linkage looks a bit odd, it is quite stiff and allows for good clearance when the front axle moves. When complete, the mounting brackets will be 2-1/2" thick at the frame and 1-1/2" thick under the blue Ford bracket. I still need to mount the bracket on the other side of the tractor but it will much easier having done all of the layout for this side. I hope to complete these brackets this weekend.

Following the mounting of the loader, I feel that I will need to add additional weight to the rear of the tractor. I raided a local yard sale and bought a bunch of 25 pound barbell weights for almost nothing. I am going to fabricate rear wheel weights after mounting the loader. The weights will be mounted on a 1/2" steel plate and bolted to the wheel. I think that 125 pounds can fit inside each wheel without sticking out too much.

Here is neat site that used barbells for wheel weights.

Calpyro, Your steering mod mad me laughed so hard that I spilled my coffee...! I've been there and done that very type of thing. I'll have to take a picture of my geardrive lift arm adjuster....same sort of thing: Pure "dogleg".
THe best example of that type of "oops engineering" I've seen was a few years ago when my buddy bought an 1950s model Massey Harris tractor. That tractor was designed with the PTO output shaft too close to the upper 3pt arm. So there was no way to mount a PTO drive shaft without interfering with either the upper 3pt arm as the implement was raised and lowered. Massey's way around the problem was to cast a special wishbone-shaped connecting arm for the upper 3pt and then run the PTO shaft through the center of the wishbone. Wish I had a picture...

I got to admit is was a bit frustrating to match the bracket up to find that the steering linkage needed to go through the middle of it. The Ford that the loader came off of had power steering and did not have steering linkage there to contend with.
rerouting the linkage was the easiest way to fix it. I even considered putting the entire power steering unit on the Yanmar but when I look closely, that would have really required some major mechanical contortions.
When all is done, the severe 90 bend will be hidden by the sheet metal and I feel confident that it is strong enough to last a lifetime.
I have had to adopt an attitude that I will need to be flexible with my engineering when mating up to pieces that were never intended to be together.
I hope that the pictures can be helpful for people that are considering similar projects.
Thanks,
Cameron

And if that link bends too much under hard steering pressure you can always borrow a page from Massey and wishbone it with a parallel link that goes under that offending loader mount...
