: :
: : : Does this tractor have a live PTO? If not,
which of the 600 series tractors has a live PTO.
Thanks for any info.

: : Some folks are confused by the term "live".
Not to say you are but for instance, the Ford "N"
series tractors had to be moving in forward or
reverse for the hydraulic pump and P.T.O. to
operate. All 600 series tractors would operate
equipment with the tractor at a dead stop and in
neutral as long as the P.T.O. was engaged.

: No, you're the confused one. "Live" means
whether the hydraulics/PTO stop when you step on
the clutch. In the Ford N's, neither the
hydraulics or the PTO were live, but they do work
when the transmission is in neutral. For example:
pushing snow with N and back blade you would drive
in reverse until the snow its pushed into the
pile, step on the clutch, put the tranny in
neutral, then let out the clutch to use the
hydraulics to raise the blade, then step on the
clutch to put the tranny back in gear.

: All Fords after the 8N (NAA's, 600's and later)
had live hydraulics. 600's had live PTO if they
had a 5-speed or select-o-speed transmission. The
4-speed transmission does not have live PTO.

: The live PTO on the 5-speed Fords is
accomplished with a two stage clutch. Depressing
the clutch halfway stops power to the transmission
for stopping, gear changes, etc. while the PTO
keeps running. Fully depressing the clutch stops
power to the PTO.

Hey guys, I'm a little new at this. I have a
600 Ford, and have just ordered a $44.00
maintenance manual--so I can refurbish the
hydraulics. I have the understanding that it could
be 1. worn/broken seal "rings", 2. a hole in the
hydraulic piston, 3. a faulty check valve.
Symptoms include: excessive "hick-uping,
failure to extract the post-hole digger from a
rather shallow hole( i have adjusted the
travel/heighth) Simply, it don't have the
lift that our Jubilee use to! I do feel that I'm
mechanically inclined enough to fix it, but I do
not have the means of testing pressure, valves,
etc...so I just plan on replacing them! Any tips?
