Ah the continuing saga, figured I better get some old pics out before I take any today.

 

Finished up the mount and adjustment brackets for the alternator, both belts on and tight.

My Planned idea for lever routing (will be tight)

And my first mock up for a lever

linkage underneath, (master link, clevis pin with slot cut in top and holes enlarged as needed, piece of threaded rod with nuts top and bottom{allows me to adjust the height} also slotted and drilled, silicone tubing pieces to tighten up the master link a little)

Looking good. That is going to be a tight fit, and a bunch of fiddling to get the levers

hooked up and on there. It'll be worth it. :thumbs:

Thanks for the up-date, have been following it as you go along ,  I  like the idea of using an automotive alternator  ,I wouldn't mine having a tractor with one .  It would let me use a good size  inverter  so I could have 120 vac at the garden or around the yard .

I had not thought of that Al, good idea :thumbs:.  Now I will have to plan for an auxiliary 12 volt connection somewhere.

The adjusting brackets look like they are good and strong.

I do have one question though ..... with that hydraulic lever arm extending out over the other valve spools, are you going to offset the other two lever arms so they clear each other ?

 

My thought was to have the third lever ( closest to you ) come straight back.

Then you could offset the first lever to the right and offset the second lever to the left.

Thanks to all!
Ray, I hope everything has been built strong enough and am anxious to get to the point where I can start the engine.  I added an angle piece across the top of the support as it had some flex in it when I snugged up the belts. 


The levers are all in and functional.  Pardon the electrical fixture screws but thats what I had on hand that fit the 1/8 inch holes I drilled, better suited bolts and nuts are on my next shopping list.

 

As usual I try to be as frugal(read cheap) as possible, and cant seem to throw any piece of metal away.  When searching for suitable stock to use for levers, this is what I found and used.  From our service pole when we were just camping on the property.

I cut the "corner" or angle off of the panel cover to length.  Then using a piece of 1/8 inch bar stock to keep it from going too far, squeezed this angle in the vice until it resembled a "U" shape.  Pulled the bar stock out to drill the holes for the pivot and the linkage, then laid the bar stock back in when I bent the angles in the vise.

The first or inside lever is longer as that is the main lift and will be used most often.  This spool has a float position and I wanted the down motion of the lever to move the blade down.  To do this I had to pivot the lever in front of the link, on the other two I can switch hoses to get the direction I want.  Not real sure what to use for knobs or ends yet but thinking some oak or ironwood pieces.

 

Things are tight underneath but it all fits and functions.

Next is the lift cylinder mount and hoses.

 

To be continued.......

That looks good Greg.

In the earlier photos you posted, I was so intent at seeing how the adjusting brackets were built that I completely missed the part where you had the levers drawn in, Sorry about that.

I just realized you had the levers all figured out before I made that last post.
