Running tractor hydro fluid in Fisher..

    I have an old Speedcast setup on my 89F250, was looking to make a mount for the blade for my tractor. Problem is, the tractor uses different fluid than the Fisher obviously, and I do not want to cross contaminate. The tractor will run the cylinders when on it (yes it will have a cushion valve), so I'd rather run the tractor (Shell ) hydro fluid in both.

    Anyone have any idea if this will casue issues in the Fisher Speedcast electric over hydraulic pump?

    Thanks, here's the two beasts.....

    I'm no expert, but I'll take an educated guess and say I'd do it. I'd try to flush out all of the old fluid from the plow pump and rams and hoses. In fact, I'd flush it a couple of times. It would be a good time to pull the pump motor and clean out the reservoir and screen, too.

    If you going mount to the tractor and run the tractor hydro system you wont need a pump on the plow just the angle rams all you will need

    defiantly do what brookside said. as long as its not contaminated and has not moisture in it you should be okay. my boss runs John Deere hydro fluid in an old fisher too and it has no problems. it may even be a good time to change the fluid on the tractor once you put the plow on and cycle it you will need to add more anyways so you might as well just drain it and re flush the whole system and start fresh.

    Good to hear that it has been done with tractor hydro.

    The setup is a Speedcast system, perfect for what I want. The pump stays on the truck, only the blade and frame with cylinders will switch between the two. Yes, I will use the remote to angle while it is on the tractor. The tractor use will be for backup, pushing banks, and knocking down rows. We get about 160" or so a year, it gets pretty high by about now.
    Just gathering parts now, this will be a Summer project. Getting an 8' blade this weekend
