Looking into picking up a 70 gasser this winter to supplement my stable of old tractors. Would like to use on 9 ft haybine, 4 row cultivator, and 3-14 or 16 plow. Have two 60s and 2 As and would like to replace one of each with a 70 and a 620/30--the independent pto and live hydraulics are important to me because we have 50+ acres of hay out and its impractical to run a haybine without these features. Now I realize the 70 is geared higher than the 60, has the two stick type shifting quadrant, and has a greater displacement. Are there any other major mechanical differences btwn the two that might pose reliability issues or are they essentially just two sizes of the same tractor? Thanks,

Pete

Either tractor, if they have been
maintained and are average hours for
their age are pretty bullet proof.
The up side of a 620/630 is the 3pt
hitch and load depth control as you
said. If you are figuring on plowing
with the 70,buy a larger gas bulk
tank. Not hard to run through a full
tank of gas in 4-5 hours in heavy
ground.

Should you happen to run across a 720/730 in your travels.It maybe worth a thought to consider them over a 70.
You pay for a lot of gasoline with a diesel engine repair bill.

60s and 70s were both built with and without independent pto . Same way on power steering.

We pulled 4x14 in third gear with a gas 70,the 4 row cultivator(3 point) was a load on side hills. As for fuel usage we filled it in the morning,noon,and after supper at night. Just dad and I,if we could work at night we did.

I didn't know that. So other than hooking something up to the PTO and trying it out, how does a person know which is live PTO and what isn't?

You will be better off to get a 620/630 machine. hyd. pressure is higher on these than a 60/70. But still may not be enough to run more modern implements ?

I don't have anything too modern anyhow so cheap is King and while I would like a 630 they seem to command a greater value than a 70. I'd be happy with either. My 60 handles the 1219 Moco just fine although the hydraulics can be a bit weak. I'd love to have a 70 series diesel but it seems like most are about beaten to death by now and too expensive to repair right for me.

The live PTO models will have a lever low on the right side of the battery box to (lift) engage, or (down) to disengage the PTO. If that lever is not present, they do not have live PTO.

Stand behind the tractor and look at the PTO. If it is centered, it is NOT live. If it is offset, it IS a live PTO.

Bottom line is what you want. I own a 60 and a 70,both have worked in the field. Presently the 70 is strictly for pulling till the urge hits again to pull the 60 which recently got a power block. Both tractors have done more than asked of them once all things worn were refreshed they are both ready for the long haul. Keep these older tractors regularly maintained they will out last us all.
