[Farmall] 660 Hydraulics

[Mike Sloane]

Going by my "Brown Book" used tractor price guide a 660 in fair 
condition might only sell for $2500, depending on the year, wide vs. 
narrow, hitch, tires, etc. - all the usual stuff.

It seems to me that a 660 is pretty much just a later version of the 
560, so you can pretty much go by that as far as what the problems with 
hydraulics might be. Plugged up filters, low fluid, bad pump, open limit 
valve, or any of dozens of other problems. "Doesn't work" just covers 
too many possibilities. A bad pump is the easiest and most costly 
problem, but some of the other alternatives can drive you nuts just 
trying to narrow it down. There is a Website I found a month or so ago 
that describes the problems someone had trying to isolate a hydraulic 
problem he had with a 460 <http://www.oldoakfarmalls.com/460Page.htm>. I 
think he solved his problems, but I gather he dug very deeply into the 
system and might have some suggestions for you when you get your tractor.
