Tractor hydraulics and snow plow rams

[perik36]

If I adapt a truck snowplow for use on my tractor do I need to flush the rams before hooking it up to the remotes on the tractor? I know that the rams currently have a low temp snow plow hydraulic oil in them.

Thanks

I would and I did. Water, dirt, salt residue, and maybe even wrong type of oil. I also suggest you use automotive brake hoses to 'wire' it up because the rams are not used to seeing 2500 psi at a high flow rate. Brake hoses will slow it down a bit.

Thanks for the input, do you think a crossover valve would be a good idea too?

Plow control valves have built in cushion (cross over relief) valves in case you hit a curb or something unmovable. A cushion valve would be recommended in between the rams and tractor control valve. Cushion valves are usually set at 3000psi to divert flow to the opposing ram when needed.

Edit: I see above you were thinking of same
