Your cylinders are going to be plenty big

It looks good how much can that lift with the back wheels staying on the ground?.

yep cylinders came off of a mining drill (no idea what they are rated to) and jack also no idea yet thats why there is half a kilometer of box section hanging out the back waiting for counterweight :laughing:

It's going to take some HP to fill those cylinders. What size pump do you have?

The pressure should be OK, but the flow rate might be to slow.

I had to put a smaller pulley on my pump to speed up the loader. It can lift over 800 pounds with 1150 psi.

faxman you are correct i finally got to test the pump out and the pressure is fine but the flow is quite slow, are you using a proper hydraulic pump or a vane power steering pump?

------------------

It is the hydraulic pump that Kwik-Way used on the loader, made for a garden tractor.

I bought it at an auction 10 years ago.


You should be able to change pulley sizes to speed it up. It was made for much higher rpm's than your mower engine is turning.

Power steering pumps usually have a built in flow control valve to limit the flow at high rpms. It may not do any good to speed it up.

bigdeano has got it, I tried it at higher rpm and it was the same speed and the pump did not sound very happy. but good news i am picking up 1 maybe 2 gearpumps after work and will hopefully try them tomorrow.
