Convert "Walkie forklift" to 3-point attachment (Lifts 11 feet high)

[Sodo]

When the 3pt is raised the implement moves in an arc,,,,,<snip>,,,,When I get some pictures snapped it will make more sense.

I'll be interested in the pics.

If your mast tips back it sounds like your top link is not maintaining a (mostly) parallel relationship to your lower lift links.

I don't know much about 3-pt. If the top link attach point is about 18 inches above the lower pins, the top link can be adjusted (in length) to raise almost vertical. I think. You might consider measuring the vertical distance from lower pins to the top link attach point while you're out there.

That is like that on almost all equitment

Since it's a single acting cylinder, it's going to drain your hydraulics every time you raise it and refill your hydraulics every time you lower it. Have you considered how much fluid it and its hoses hold when its fully extended and will it lower the level in your hydraulic system so much that it may effect other things or cavitate your hydraulic pump?

If it was a double acting cylinder, it would fill the opposite side of the cylinder as it moved in the other direction. It wouldn't be such a big deal. But since its a single acting cylinder, its a genuine concern.

Look at snow plows. They have two single acting cylinders. When one fills, the other drains, and vice-versa. Its basically shifting the volume from one cylinder to the other. Not in the case of this forklift. Its shifting the volume of the hydraulic oil from your hydraulic system to the cylinder and back.

Just something to watch for.

Good point. The lift has 2 cylinders to fill (1st & 2nd stage). I can calculate appx amount of oil to fill each cylinder. How do you find out how much hydraulic oil the tractor has to offer?

Go to tractor data.com. and enter your tractor in the files

Ok simple enough. I've looked thru those before but never looked at the "walkie with two 2.5" x 36" single acting cylinders" column

The spec for your tractor's hydraulic capacity will probably give you a hint

IIRC, it's 3.83 gallons ...

Not counting hose volume, "walkie with two 2.5" x 36" single acting cylinders" will hold just over a gallon and a half.. Steve

Perfect thats how much I got out of the walkie's tank!
