Ford 4400 industrial

My question is that every time I engage the PTO lever. The PTO engages hard, there is no easing into it. Is there a reason for this or is that just how it works?
 
That is also my complaint about the
tractors with Independent PTO. That
hydraulic clutch pack hammers the pto
into gear so hard and no good way to
feather it in. I've asked about it here
too and was told that other than
throttling all the way down when you
engage the handle there's not much to be
done about it.
By the way, according to Ford Tractor
Division a 4400 is not an industrial
model. It is a utility model.
Meanwhile, welcome to the forum.
This is the best board on the entire
internet for info on the Fords of that
era.
 
Thank you for your response. I was finding out that there really wasn't any easy way to engage this. I was going to post this as well. Any idea why I would loose PTO power and 3 point hydraulics when ever I go up hill? I have checked my fluid level already and it's full..
 
There are actually two seperate hydraulic
pumps on those. A small one for the pto
rides kinda piggyback on the main one for
the 3 point lift.
How and where did you check your fluid
level? To have both fail to work going up
hill does sound like a low fluid issue.
This is a different variant of a 4000
than yours so a bit hard to get in there
for a good photo. I think you can see the
pen pointing to the square headed plug
which is your oil level check.
Yours should be the same.

Yes that is the plug that I pulled to check my fluid level. I have a full set of manuals for this tractor. I'm about to see if there is a oil pickup tube.
 
I read about a bleeder screw so I'm currently searching for those on both PTO and lift arms. How ever today I engaged the PTO very slowly and was able to ease into it. With out it just slamming in.

That's what, in the Operators Manual for later models, they call "feathering " the control. On some later models they actually added a detente in the control and you were supposed to move the handle from fully disengaged position to that detente position and pause a second and then slowly move it the rest of the way to the fully engaged position.
 
Don't think there is a hydraulic bleeder
screw on a 4000 chassis with IPTO.
Your gear pump is always immersed in oil
down in the bottom of the rear end and
self primes. On all 3000 chassis tractors
and 4000s with transmission pto the
hydraulic pump is a piston pump and
engine mounted - left, rear corner of the
engine. They have two steel lines that go
from the pump to the rear end. Those do
require bleeding on occasion.
I think you may be on the right track -
that some kind of blockage may be
occurring on your suction screen when you
climb a hill.
 

either the pickup tube is cracked/bent/distorted,,

Or...you low on fluid,

Or.. the hill is very steep and the fluid all runs to the rear momentarily and the pickup tube sucks air.

I have a wonderful creek running through my place. Years ago, I round off all the edges from a 6' to 12' drop off, .... to a nice gradual slope. This creek area now......is always my BEST hay getter... as it always has the tallest, thickest hay now. But when I run down the field in the long direction and cross the creek, my 6700 would always loose the pto for just a moment on the steep uphill side, coming out of the creek. After a lot of checking, I decided it was just due to the steepness and the tractor was normal in all other functions. And only the very steepest slope in one small area cause a momentary blip... So I reverse the direction in that one part of the hay field.


Not saying this is your problem...
