The pto works intermittenly. - Cub Cadet Street Sign- tractor lawn riding mower parts

Check the wires.The electrical connector between the tractor's wiring harness and the PTO wire gets deformed. The wire gets heated.It can be from engine heat or from heat from the electrical connector itself. The red wire connection gets only making marginal contact as a result.And this PTO switch looses it contact and again re-gains its contact. You can try to realign the connection and see if that helps.But if that is not helping then ultimately cutting the connector out completely and replacing it with crimped spade connectors will help. You can get this connectors from local electric part store for cub cadet or from from Radio Shack online site.In most of this cases this wire getting shorted is the issue.But there are few other possibilities, also get that checked. Battery problem will cause major trouble with the PTO. It takes an enormous amount of battery energy to run an electric clutch. So if your battery is low...or goes down, the pto cannot work. Even if there is enough power to start the engine.You'd have to have the charging system in the mower checked.The PTO switch could also be bad causing this problem. This happens fairy often.Also check the wires that attach to the pto clutch. If they came loose, it won't work. Also check for any corrosion on any of the wire terminals and also the battery post and terminals. Also check to make sure that there is not corrosion on the ground cables.Last but not least, the PTO itself could be bad.... or at least need adjusted.Remove and re-adjust the pto and check.------------ This troubleshooting will help solving the problem.---------- Thanks.Helpmech.
