Lane Ranger 11,023 #1 Posted July 12, 2016 Does anyone know if the PTO hitch pin clip used on the Wheel Horse tractors ( like the B-80) is hardened like a grade 8 bolt is> Share this post Link to post Share on other sites

Lane Ranger 11,023 #4 Posted July 12, 2016 Well no problems but I am using on as the rockshaft pin on my 701. The 701 has one center hole in the rockshaft and the hydraulic cylinder lift piece that is in the center of the rockshaft. About a 1/4 inch hole. My bolt in there sheared using the cultivator the other day. I like the PTO type hitch pin with the lock on it as you can see it and remove if necessary. I just don't know if it strong enough. I put a 50 lbs block on the cultivator and no problem lifting it. But when under stress from pulling in the garden will that be strong enough ? I did find this interesting article about Tractor Hitch Pins from the Purdue University Extension. Lots of very good and detailed information in the article.

KC9KAS 4,741 #5 Posted July 12, 2016 @Lane Ranger I'm sure there is a lot more weight/pressure on the pin in the rock-shaft than when it is in the PTO. Leverage is everything when you are trying to "move" something. 3 Share this post Link to post Share on other sites
WHX?? 49,483 #6 Posted July 12, 2016 you could try a regular and keep an eye on it Throw up a link to that article Lane 1 Share this post Link to post Share on other sites

Achto 27,908 #9 Posted July 13, 2016 Here's some thing to think about. If you have a receiver style hitch on your tow vehicle all the weight on you trailer is being pulled with a 5/8" pin. 2 Share this post Link to post Share on other sites
Lane Ranger 11,023 #10 Posted July 13, 2016 (edited) Ken: I don't have the details but someone did tell me those small hitch pins -like the ones we use on the Wheel Horse PTO's are supposed to be hardened when made. I found this website catalog listing by Wilson Manufacturing , Inc. of a number of different type hitch pins http://wilsonmfgco.com/products/pin/ Interesting History of the company that makes these. http://wilsonmfgco.com/about/ Edited July 13, 2016 by Lane Ranger Share this post Link to post Share on other sites
Achto 27,908 #11 Posted July 13, 2016 Lane, those pins are also available in a 5/16 size. You could drill your hole out and go to the larger pin. Share this post Link to post Share on other sites
Lane Ranger 11,023 #12 Posted July 13, 2016 (edited) achto: No drilling the hole out on the center hole in the 701 rockshaft was one of the problems with the early design. The 3/4 inch inner shaft on one I bought as a model to make another one was broken in two. It could not take the stress. The hole had been driller out wider. The 702 version has two holes on the outsides of the rockshaft and the 1963 versions had to have a solid replacement rockshaft with with no 3/4 inch inner piece and no holes for a pin as it was not needed.

oldredrider 2,553 #13 Posted July 13, 2016 Lane, to determine hardness of the hitch pin, take a triangle or flat file and try to "cut" a groove in it. One or two passes should be sufficient. A hardened shaft will only show a mark where softer steel will have a groove. 1 Share this post Link to post Share on other sites
