RPRU

Did any one else go to red power round up today and what did you think of it

I was there today and yesterday. In my thoughts it was a good show. Not as big as the last few years, but had many unique exhibits. I had never seen cotton pickers up close or in operation before. I took a tour of a cotton processing facility. It was very educational. On the down side the women activities were not much to talk about. I know that I had some contact with others from YT without realizing it by the phone call I had with grandpa love. Unfortunately I spent time on a couple of tours, so i was not able to meet for some meet and greets.

Hey IA1456, I sent you an email. If you are at rpru Fri hopefully we can meet up. We will be there all day after 9am. Kevin in Central AL

I went Thursday . It was my first time to go to a RED TRACTOR TOUR . I enjoyed seeing the models I have read about on this forum and some I never dreamed existed and the custom built tractors . My wife seemed to enjoy it fine too . She is not one to get too excited over a tractor but really enjoyed the parade . I didn't find any parts I needed but got leads on where to go to find them . I forgot to ask about the meaning of TA as I see it on here often . What is it ? What does it do ? How does it work ? My small tractors don't seem to have such a thing .

TA is a Torque Amplifier, it's the first shift on the go speed reducer or increaser put into production by a major tractor manufacturer, on the 1954 Farmall Super M-TA, reduced speed 33%, increased pullling power 45%, was a planitary gear reduction with an over-running clutch, Super W-6 TA had it too. In '55 the 300 Farmall and Utility had it too along with the 400.

I don't think any of the Louisville built tractors got the TA until many years later, Just Farmall Plant built tractors. The W-9/600/650 never got TA either, they were built at the Milwakee Wprks and later Melrose Park Illinois plant.

Live PTO was another feature of TA equipped tractors, the TA would have reduced 540 pto to 356 rpm.

Dad got a lightly used SM-TA about 1960, traded it for a 450 gas spring of '65. Both were grwat tractors, the TA was a great productivity improver on our hilly ground. Many other companies tried something similar, like Allis Chalmers Power Director, but it had a break in power. Minneapolis came out with the Ampli-Torque which was out and out copy of the TA. Oliver probably made the best copy, and later made an Over-Under Hydral Drive. TA did not sap Horsepower like the Select-O-Speed of Ford, or Deere's Power Shift developed by the same engineer.

Dr Evil the ta would slow down the belt pulley but had no effect on the pto speed. I think you are testing us.

Thanks for the info on the TA . It sounds like an overdrive on an automobile .

It uses a planetary set to slow down the ground speed instead of increase it. It is similar to an overdrive in an Auto but is driven faster than it outputs, just the opposite of the OD unit in an automatic transmission.

On mechanical TA versions, when in Direct, it spins the Entire ta assembly for 1:1 with no reduction. When you pull the lever back it releases the TA clutch and spins the planetary gear set, while the ramp/roller (overrunning clutch) assembly operate as a brake to keep the TA outer assembly from spinning backward. The overrunning clutch only works as a brake in one direction, because the TA assembly needs to be able to rotate when in direct. This is the reason the tractor will not hold back when the TA is pulled back.

I also went to red power roundup the past two days. It wasn't nearly as big as the one I went to in Wisconsion two years ago, and the factory tours were a nice touch at that one, but this was still a good show and the rain managed to hold off so we had two good days of the show.

My first time to RPRU. Went Friday. Had been planning to attend for over 2 years since first hearing about it. It was great show and obviously largest I?ve been to but was also somewhat disappointed. Tractors were fine although expected more and some with implements. Also figured be more parts suppliers. I?m certain the northern shows much larger.

Overall. Enjoyed it.

For anyone who missed it, here is a slideshow of most of the tractors there. https://youtu.be/vsdKp-1Sf2U

I went Saturday. It was hot and humid even for an Alabama boy. I was thrilled and disappointed at the same time: the tractors that were there were awesome but, I?m guessing, due to Father?s Day, many people packed up and headed for the barn Friday. From the pics I?ve seen there weren?t near as many tractors Saturday as there were earlier. I was thrilled to see two 240 Utilities, however.

I seen a few people loading up on Friday, mid-day to leave, and on my way back home to KY on Saturday morning I seen a few on the road on their way home. I went on Thursday and Friday and it seemed like there were more there early on Friday than there were on Thursday, but there may not have been.

Someone said there were 500 tractors there, but I took pictures of almost every tractor there and only had 160 some pictures, including the trucks. There couldn't have been more than about 30 cub cadets either.
