Looks like a wagner WF3
Steve I had a Wagner loader on my 8N. I took it off and sold it to a guy for $50. It did not do what I needed it to do because it was first of all to heavy in itself and second, the front end of the tractor where the loader was hooked to, was not strong enough to lift anything I wanted to lift with it. I had to replace all the fastners that hooked the front cross member to the frame. But, you may have different results. Don't let me discourage you!I found the tag on the valve it says Wagner Iron Works V-3. So I guess Kirk is correct. I'm not sure what Fred is talking about.
How hard is it to repack these valves? I got a drip and my right boot is always darker than my left.
Have a nice day
