Which transmission do you think is best overall the power director or power shift? I mean reliability and ease of use etc..

My vote is the power director on reliability, but in these missouri hills I'm pretty much limited to 2 gears. I'de like to hear the answers on this because I think a powershift would be nice.

Never used a PS but have been told the gear spacing is less than desired for tillage. My PD has a great selection in the 4-8mph range. PS would be great for haying and loader work....so they say.They were both reliable systems.Anything after 5-7000hrs can start showing problems.

In my opinion the power director is bulletproof while the powershift is nearly bulletproof. I've had three power director 7060s and one 7080 and never had a problem with any of them. I have an 8050 and an 8070 powershift and I haven't had a problem with either of them so far, but they don't have near the hours my power director tractors had. I know my local dealer has been in a few of both kinds of trans over the years and said that some powershift parts are hard to find and may be NLA.

I used to use my 7060 PD for everything on the farm (even mowed road ditches with a 7' Woods a few times) but it was my planting tractor with a 16 row notill planter for many years. Two years ago I bought an 8070 PS and started using the 8050 PS for planting, it really is an improvement both in convienience and comfort, the PS works great for that use. As far as a tillage tractor, I never had a problem with the available speed ranges in the PS in either the 8050 or the 8070.

There are a few 7060 p.s tractors I know of around here with 15,000+ hours that have never had transmission work, so I would say they are pretty reliable.

I enjoy hearing about the reliability of the 7000 and 8000 drivetrains. They took a lot of abuse during their testing at the proving grounds back in the day. That doesn't always translate into actual field reliability, but it evidently did where these tractors are concerned.

We had a 8030 PD and still have an 8070 FWA with the powershift. I always thought the PD trans worked great in the field as the 8030 used to be my sprayer tractor and 5th on the low side worked great for spraying. The powershift on the 8070 I would say that for tillage alot of times 4th low is to slow for discing and sometimes 5th low is too fast and will lug it hard on a 25ft 496 disc in our rolling hills in southern IL. That is when sometimes we will run in 1st high, but then no downshift. The powershift on the 8070 does work great on the grain cart. The torque limiter has been the only issue that we have encountered on either tractor.

In the early days, the tractors were driven around the test track or across the bump track. Later, a really wide wheel track cart (wider than the bumps) and remote controls for the tractor was used when running the bump track. Also, in the 70's, large chassis dynanometers were built that could run 24 hrs for drivetrain durability tests. There were a lot of switches and sensors that would shut the tractor down if something went wrong.

I've had both, and given a choice, I will always take the power shift.

We have both, and run them hard, and sometimes the oils don't always get changed when they should, etc. We have never been into the Power Director on any of them, We have been through the Power Shift once, and it needs it again, but it was used on a loader tractor pulling a hay grinder all over God's Creation, doing custom hay grinding. That tractor has two overhauls on it too. We estimate that it is in the 20K hours range since the hour meter quit when it was still a row crop tractor, and it had 6K on it then. We are just now needing to go through the two speed in the 7060 PD that replaced the PS on the loader. I think the loader tears them up quite a bit. We never had any problems with the PS until we put a loader on it. Lot's of low RPM shifting, and tons of forward reverse shifts
In my opinion both are bullet proof, as is the rest of the tractor!!!

Neighbor put 12,000 on a 8050 powershift before it went out. It did field work, pulled a big manure spreader, and had alot of hours going back and forth pushing and packing silage. He could tear up a piece of angle iron if you gave him a chance.
