I purchsed this 350 rancher leftover in 2001 and it has been great to me. Last season while pulling a disc on my deer lease it started making a noise...

It sounds like an overpressure relief valve letting off. I certainly do not think that is what is happening, but I do not know. It sounds like a high pitched, Peeeeeoooowww about a second in duration. Kind of like pressure building up then letting go.

Has anyone had this situation? It is obviously something to do with when it is under a load and hot....

I know it is a long shot if anyone can help with this, but I thought I would throw it out there....

Thanks, Whitetailer
