I have had several 990's and really liked them but its been a while so it was time for another one. After a good carb cleaning and adjusting the points it runs great. I also put one front tire on it. The hydro is sluggish though so I changed filters which didn't help but when the fluid came out I had a pretty good idea that it might not. Lots of metal shavings including some big ones. Looks like some hydro work is in order. It has type F fluid in it,someone suggested flushing and going to a thicker fluid like a 10 30 or 15 40 might help until I get to fixing it right. I don't know if that would help or not.

Nice Tractor! I have worked on skid steers and larger tractors hydraulics and when I have found metal shavings it was time to rebuild or replace parts. Even if you flush the system and get every little piece of metal out, then you still have a worn or broken part just waiting to fly apart and destroy everything. Are you going for full restore or are you keeping the petina?

Its a good straight and solid original Merle and those are my favorites,so most likely it will stay original.

Glad to here it. Someone the other day on here mentioned "Owatrol". It is supposed to stop the rust and preserve the patina. I have not tried it myself but I do have a Continental that I want to try it on.
