Macgyver 90 #1 Posted July 29, 2018 I have a 520H with the rock shaft & cable in place. The rear hitch does not have much up down travel. After studying it for a while I decided to bypass the rock shaft and run the cable direct to the hitch. The hitch now has about 4" more travel. Has anyone else tried this and can anyone come up with a down side to doing it this way? Share this post Link to post Share on other sites
cleat 4,936 #2 Posted July 29, 2018 Did you have the chain in the correct notch in the rock shaft ? Bottom notch will give you the same movement you are talking about now. Is your cable the correct length ? Trunion adjusted properly ? Share this post Link to post Share on other sites
lynnmor 6,762 #3 Posted July 29, 2018 Without the rockshaft, the cable will not have the leverage advantage and that will put much more strain on it. 1 Share this post Link to post Share on other sites
Macgyver 90 #4 Posted July 29, 2018 There are no notches in the rock shaft the chain has a fixed mounting and yes have made all the adjustments that can be done. My question is there any problems with running the cable direct to the hitch it seems to work fine with more travel. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,488 #5 Posted July 29, 2018 Don't know what model of hitch you have but this was a modification for an earlier model. Click on the pictures Going straight to the tiller will likely increase the effort to lift. A later version Here is a later one with the notches The last version Garry 1 Share this post Link to post Share on other sites
