I dont get this. My 3PH is single- acting. You can lift the empty links with your hand. Any implement on wheels or rollers just rides over bumps.
Good to see you back BTW.
Thank you.
Sometimes, when the tractor is going through a depression and the back wheels are going into the depression, the mower rear wheel or roller induces a twisting force because of it's leverage advantage . The 3pl gets bound up and the result, if you dont have chains on the headstock, or a slotted top link hole, is bent components .
That is why chains are usually fitted to the headstock of most Bush Hog's etc. so the mower can pivot on the lower hinge of the headstock . If the mower is fitted with solid steel straps, instead of chains, the top link on the Tractor must be flexible enough to absorb the change in angle .
It is hard to explain in text . I will add a photo from TBN to try and visualize it . This Bush Hog is fitted with chains on the headstock and you can imagine what would happen if it didn't have them .
