350 utility

I bbought a nice 350 utility for my dad at an auction this spring. Now we want to put it in the field and have a problem. Where do you check and fill the hydraulics on a 350 utility? I have newer ih tractors and am not familiar with the 350 and dad hasn't run one since they were nearly new and has forgotten. Also the pto slips. Would that be like my 756 and 1066 and not work properly if the hyd level is too low? Thanks
 
There should be a plug on the top of the reservoir, near the front. It should have a square boss on the top that takes a 7/8 wrench. That plug should have a dipstick. Since the tractor is over 50 years old, though, your plug may have been replaced and wouldn't have a dipstick. Seems I recall it was maybe 2.5 inches down to the full mark, though.
 
And the hydraulics would have no bearing on whether the PTO works. But if you have trouble getting the hydraulic pump to prime, you can help it along by pressurizing the hydraulic reservoir thru the vent opening. I used to use a rubber tipped blow gun, and with the tractor running and the air pressure in the compressor turned down to about 5 psi, blow air into the vent opening until the pump primes. You can hear the change in the engine sound as the hydraulic pump starts pumping.
 
PTO adjust.
The linkage on well used PTOs on the utility series become dysfunctional after years of use.
Two suggestions:
Make very sure there is no lost motion in the hand lever pivot and rod mechanism. Be certain the hand lever moves the PTO lever from the middle both ways.
Adjust it like this, after there is no play in links.
Move the lever exactly half way between the locked on position and locked off position (little flipper catch on lever.
Take off the little dome metal cover from the adjust screws.
Loosen the jamb nut, and tighten the front (away from you) screw until it is just a bit tighter than the point at which it begins to feel tighter as it is screwed in (maybe a eighth turn) then back it off until the PTO shaft will turn with least drag (about 3/4 turn out) and tighten the lock nut while holding the adjuster.
Do the same for the closer adjuster.
If the screws go into the jamb nuts and get flush with the top surface of the nut, the bands are probably worn out, and may be operational for a while, but plan on a rebuild.
Now (tractor off) push the the lever down toward the brake footplate. As it goes down, it should get harder to push when it is about 4" (or so) away from fully OFF. and be noticeably harder to push for the last inch, but not real hard. (this is the brake band tightening on the drum in the PTO unit.
Then pull it up and do the same feel.
The ON position should feel the same way.
The shaft should turn pretty free when the lever is half way, and not at all when in either ON, or OFF. (tractor shut off)
If it slips now, it needs a rebuild. Jim
