IH's Torque Amplifier

I was reading over on the main board about this fella who has a 1086 with 13,000 hours and he has this tractor in the shop for it's 7th T/A.

It got me to wondering why some folks have so much trouble with the T/As and others don't.

Again, I can only speak from 'my little world', but T/A troubles around here are the rarity rather than the norm. Clutch issues aside, very seldom would a tractor ever need a T/A more than once in it's entire lifetime.

Do you suppose it is the regional thing again? The hill country vs the flatland?

Dunno, just seems odd,

So people give the Farmall the bad name. Never could figure that one. I think the one that wouldn't run at all until repaired, deserves the bad reputation. People are fickle.

Some folks still just don't know. For example when I see a guy give advice on not allowing tractor to free wheel, we know he doesn't know much about TA. Probably less than 40% of TA equiped tractors actually did or would free wheel. Lets face it only 00, 50, 60 series plus 504, 544, 656, 666 and 686 actually did free wheel. All others did not free wheel.

I use the T/A hard and we never lost one that was good when we bought the tractor..... .....granted, we did buy more than a few with a T/A that was shot from the begining.

T/A is operating with the lever back and all ya do is give 'er a yank or shove it forward.

You don't feel a decrease in speed, increase in torque when you pull the lever back? Wonder if someone has welded the thing up rendering it inoperative?

I've been around these gizmos since the days of the old 400Ds and to be honest about it, I didn't even know that they gave any trouble until I started reading the posts on this board.

Well, that and not until I bought this old heifer from down in the middle of Iowa. The T/A in this one was completely hammered out, but it still pulled okay. The clutch was slipping is all.

I just figured it was something you guys had in the water down there. :>)

I walked home and called my buddy down the road who had a brand new 400 or 450. He came down and we went to the pit and threw a chain on the H.

He started pulling, nothing's happening. He cranks it up and after a very short time, smoke just starts pouring from the 400's center section. I hollered to him as to what gear it was in and he said 4th. I said something about his intelligence and told him to put it in 1st. He replied "Well, 4ths OK 'caue I got the TA on!"

I always waited for that tractor to explode after that, but it never did to my knowledge.

Oh yeah, walked the H right outta there in 1st.

To your 2nd question TA just slows tractor about 30% in each gear. Your tractor at 15 mph is about average. Very few are much faster than that.

Thanks for the info confirming TA on these. I was sure I drove one with TA, but this little book wasn't saying so. It didn't say no either. It just listed 66 series as 8/4, 16/8 with TA. When it came to 574 and 674 8/4 omly. This wasn't the full IH buyers guide for 75, just a pocket version containing only tractors, loaders and tillage eq.

They were a very popular tractor with dairy farmers. They liked the short wheel base for square baling and haybine work. TA would have been quite important as well for those jobs. There is a guy in my home town claims 574, 674, 584 and 684 have baled more hay than all others combined. I'm sure he is right for that imediate area. I used 560 and 656 for those jobs, and he called the 560 the ark. He did agree 656 was a bit better.
