666 pto problems

Posted by MikeR001 on August 25, 2005 at 19:29:21 from (70.33.152.41):

I have a Farmall 666 diesel which starts/runs just great-the problem is the pto. I only use the pto to run a 6' bush hog-I hog about 100 acres a year of mainly grass (CRP land) but also some small trees which are less than an inch in diameter. About 8 years ago, the pto began to slip so I had it rebuilt. About 4 years after that, it was slipping again so I had it rebuilt again at a second shop who said that the first "rebuilder" had used some parts which were pretty well worn out. Here I am another 4 years later and the pto is slipping again! Some discrepancies-1) I have not used HYTran but instead tractor hydraulic oil 2) PTO speed under load is about 1800, not the 2000 rpm that it should be. Any ideas? It's about $600 to rebuild the unit! What am I doing wrong?
