Driveline shaft on Bush Hog SQ720

volunteer · Jun 3, 2009

This afternoon I went to hook up my SQ720 to my Ford 3930 tractor and everything hooked up as normal until I got to connecting the SQ720 driveline shaft to the tractor PTO. It took an incredible amount of pulling to get the driveline shaft to inch up to the PTO. I finally gave up and called a dealer and talked to mechanic. He said to take the collars off, separate the shaft, and wire brush, then grease. Well I had no wire brush so I was able to get collars off and proceeded to clean off the old grease. I found a label had been left on the male end that figured that was what had "clogged" the works. So anyway, I removed the label and adhesive and greased the male end of shaft. Still almost impossible to slide these two parts - which used to be easy.

According to SQ720 manual, the inside of female shaft is supposed to get the medium duty grease. I see possibly buying extremely small wire brush, duct taping to metal rod and wire brushing inside of female shaft?

Any help appreciated.

Maybe a swab made out of something stiff piece of rag on end soaked in kerosine or something like that? better make sure rag is secured to end good though.

Thanks for idea on rag and kerosene . The last thing I need is a rag stuck in a driveline. A small wire brush, like a toothbrush would be easy to get out if it came loose, maybe. Thnks for idea.
