Steal one of those little ones off a Vickers hydro if your temp runs too high.

Lots of options on ebay. There is room for a small one under the gas tank.

I got a good start on fabricating brackets today.

 

Pump mount. It took a while to holesaw drill the pilot hole.

Left side valve lever shaft hanger bracket.

Valve linkage. Shaft needs to be cut yet.

Valve lever. Needs to be bent yet, at black marker line. I'll do that once

I get tires/fender/seat/and me on it.

Cylinder mount. Not done with that yet. I'm going to brace the pin back

to the square hole in the frame.

One thing I forgot to mention in my last post, is that I might need some

ideas for a torsion/centering spring set up on the valve lever.

Right now the handle is too long (about 12"), and leaning back. Today I'll put seat

the seat on and see about cutting/bending it to a comfortable/usable

position. That should help, but I may still need to do something else.

What about a detent pin (ball and spring) attached to the handle that locates into a plate with holes attached to the chasiss to hold it in the desired position.

Is the handle hollow or solid bar?

Maybe I missed it but why are you routing the lever to the other side of the tractor? why not run it right off of the valve? does the pump's valve have it's own centering mechanism?

Solid 3/4" handle. I'm more concerned about returning it to center. Just in case it gets bumped

or bounced around, or even if I just want to let go of the handle after dropping or raising the hitch.

Yes, pump valve has it's own centering spring, but it's not strong enough to over

power the weight of the handle.

The reason I've routed the handle to the right side, is because I tend to look over my right shoulder.

It's more convenient on the right side, while steering with left hand.

 

 

Today, I finished up the cylinder mounting, and lift strap.

Also tweaked the valve lever. I had to lengthen the pitman arm, to reduce the lever

travel.

Will, you are over thinking the centering setup. You need two identical good sized springs. You mount one forward, and one backward, on the lever at equal geometry. Make any sense?

Yes, but one needs to be adjustable.  Say an inline turnbuckle or something.

 

Make sure the springs are straight pull or further out when at "center" and not when its one side or the other.  This can cause binding.

Might take a bit of experimenting to get the spring tension and stroke right, you don't want it so the lever is real stiff to operate but you also don't want the lever to bounce back and forward with momentum as you drive about causing your hydraulics to operate.

I can see Will, obliviously driving around, his plow going up and down and making a stitch pattern in his wife's nice front lawn... :rolling:
