[AT] Ford NAA

[Richard Fink Sr]

Hi all as always i have a question. i have a 54 ford Naa, question on the 3 point, When i purchased this tractor it had a 5 ft brush hog on it. Most times it would not lift it, justa growl or chatter like noise. i sold the brush hog. Now i thought i would look in to this problem, But empty is works great. Please what am i looking for. I know nothing about 3 point lifts other than they are hyd. BIL says there is a piston under the seat cover that is most often bad replace with new style. All advise is requested.
Thanks
R Fink
