PTO speed on an H

farmerwannabe · Aug 13, 2008

Hi all, our 1942 H is seeing a lot of use pulling our JD 14T baler. I have no idea how fast the PTO is spinning so I don't know how fast to keep the engine going to keep the PTO speed in the optimum range. Any suggestions? Also, I changed the throttle to one of the newer styled ones..wow, is it nice to not have to keep a hand on the throttle at all times. Thanks again for your help.

If the governor is adjusted correctly,it should be around 600 RPM with no load and 540 RPM under load.

You can get a hand-held tach to check...

On my A I used an electronic hand tach to measure the PTO speed and marked the throttle at that speed.

Check the baler manual for strokes of the ram per minute, the mark your throttle accordingly. With throttle marked you get same speed every time, SOMETIMES these old balers will act funny at one speed but not another.

Run that H around 3/4 to full open and you will be just fine. That 540 RPM number is a magic number and a baler does not care all that much. BTDT many times on many balers and most of the time I run wide open and never had a problem. I have baled with Olivers, Allises , ford etc etc etc and none seemed to matter how fast or slow the engine ran the baler did what it should have with no problem. Now on the other hand some tractors didn't have the weight or power and that when you have a heavy windrow did cause a problem with stalling the tractor

You have to run the baler at near top rpm so the flywheel has enuf kinetic energy to push thru any big chunks (wads?) of hay without breaking the shear pin in the pto shaft.
My wife"s grandfather used to bale with his H at about 1/3 throttle (didn"t want to wear out the tractor motor, I guess), he would hit a big bunch of hay in the windrow and with the fly wheel spinning so slow the tractor"s governor would kick in and the shear pin would break; he spent a lot of time on his back putting in new pins. I talked him into letting me on that H, I reved it up and his eyes got big for fear over his baler, but we never broke a pin after that.
However, I suspect when I wasn"t around when he baled again, he went back to 1/3 throttle and laying on his back a lot. LA in WI

Sounds like my Father-in-law... he complains about his vehicles not having any power, so we go for a drive with me behind the wheel... I hammer it to the floor and we lay rubber and accelerate at a quick pace - his eyes get big and he says I'm going to blow the engine and I'm wasting fuel. I respond with "If it blows up, it was going to anyway and it takes fuel to make power!"

If you hurt your baler running it full throttle with an H, it was bound to break anyway.

Running a Vermeer 504C (5x4) round baler on a Farmall 504 diesel (46 PTO HP) I start the bale at about idle in 2nd gear. Then once the "slug" forms, I start increasing throttle to about 1800 - 2000 by the time the bale chamber is full. I can do this on flat or hill.

Running the NH Hayliner, I run the Farmall at about 1800 - 2000 at all times. Keep the H at 3/4 plus and it will hammer squares out all day.
