GROUND SPEED PTO

[redman135]

Hello Travis-R, the ground speed pto is obselete these days.
How ever when I was farming I could use ground speed on the PZ tedder if the lucerne (alfalfa in US) was a bit dry and not loose to much leaf. Apart from that I never used ground speed.

Groundspeed Pto essentially links the PTO to the transmission, the shaft then turn at the same ratio as the rear axles, and same direction.
So as you speed up ground speed, the pto will turn faster, change direction it will do the same.
It's still a feature available on new tractors today. In fact i currently have one in-stock with this option on it.
Market gardens tend to use it. Also really usfull if you want to drive the wheels on a trailer, this is where it was used the most on old, non 4WD tractors, by driving the trailer wheels you now have a 4wd tractor/implement, on new tractors, this would now be a 6wd machine. Really good for big trailers on hilly, soft country.

if you ever get a post hole digger stuck. You can jack up one rear tire and put it in reverse and ground speed and back it out

That's a real good idea I never thought about that

Are you saying the the PTO turns in reverse if the tractor is in reverse? I cant say as I have ever looked at mine when it is in GS but, I have never heard of that before.

Can't say regarding the GS setting, but if you have a LIVE PTO, turning in reverse is not possible. The PTO turns with the engine.

Perhaps with the PTO in GS setting and the gear box in neutral, the PTO shaft would turn with the drive wheel direction. Worth a test.

if you had bad conditions and need to power the driving wheels on a trailer to help keep moving sounds like a good idea I know some military trucks had a system to power trailer axels

a trailer with and one with out, big diffrence

I am very glad to hear Massey has kept the option of GS pto. For just a homeowner mowing it isn't really a big deal. But we make hay and my grandpa had MF tractors and a MF hay rake. You can always get a MF hay take cheap because no one knows how to use one. You see MF hay rakes run off the pto which is way too fast if you use live pto but GS is perfect. Also if you cut hay with a gay conditioner you will clog from time to time. With a MF instead of digging it out you put it in GS and back up it spits it right out. Also do that with a round baler from time to time. Have done it with an auger before as well. We have also used it to diagnose issues with pto emplements just put it in low gear and it turns very slow so you can see it better. I also like the 2 stage clutch for engaging the pto slowly without the bang. I would love to have GS on all my tractors. It can really be a lifer saver. So now you know that it is very useful in the correct conditions.

I've seen it used to drive the belts in a precision vegetable seeder, instead of relying on ground drive wheels.

if only the PTO had its own little mini transmission. that could be directly tied together to the main transmission.

is the clutch a "double clutch", first pressing down dis engages tires, all the way pressing disengages pto? so you end up with an adjustable speed PTO?
