I have a brinly rear blade on my 990 and i have a 40 pound weight chained to it. It sometimes has trouble lifting it very high. Now this hangs off my three point so it's back there pretty good, but I'd think it would handle what I'm doing, I'd like to put more wieght on it. Has anyone adjusted thier 990 lift power?

I have bumped mine up. It will lift over 200 lb at the drawbar. I skid out firewood with it and need more weight in front to be able to steer.

It has been awhile since I did mine but I seem to remeber using a socket to get the locknut off. My set screw is in too far to for the locknut and the acorn nut. I put the washer and acorn on and left the locknut off. The lift rate is not faster, just picks up more weight. When I did this the first time I turned the set screw in till it bottomed out and promptly blew the orings out of the lift cyclinder. The happy meduim for me was just making the front end light. My setscrew is an allenhead and it turns easy once the locknut was loose.
