520-H hydro lift capacity

[1990Onan520-H 15]

Does anyone know the maximum weight the 520 hydro lift can handle? Granted I know things like how far out the weight is and such matters, but ballpark. For example, if I had a 2 stage snow blower and added weight on top of it, at what point would the lift fail to operate or damage itself trying to lift something?

ive put weight on my lift before, myself and the dozerblade wich was around 250lb and it didnt strugal so i would think 400 or so. it also has a release valve so it should not damage anything.

That's an old thread my friend

The 60 inch deck is about 350lb, and it yanks it up like it's nothing.

 

The weak part if there is such a thing is the center tower itself. Older 520s tend to have stress cracks around the bellcrank if it was used with a 60 inch deck. Adding weight way out on a leveraged blower might be asking alot, but I live in NC and wouldn't have a clue about one. We used to joke about setting one in a puddle with dish soap and blowing bubbles for a kid's birthday party but otherwise I'd never have the need for one.
