Honestly those old New Hollands are pretty good as is for staying level through the lift range. So it would be a lot of extra linkages and wear points to accomplish very little good. Would work fine in a computer simulation, but in real life it just wouldn't be worth it...

This thread made me realize I don't have a single picture of my sassy-pants New Holland L785...

So you get a picture of my forklift unloading another New Holland skid steer I purchased with a bad engine.
