Seat Tension Adj...WTF???

You long time Case guys probably allready know this but it has given me fits on two 70,s so far until I finally tore the seat off and saw how they worked. Every operators manual I've seen so far is backwards on their instructions on how to adjust the tension on the T-bar type seat adjustment. They all say" clockwise to increase tension for heavier operators and counter clockwise for weaker spring for lighter drivers" . Both the 1070 and the 970 I've had or have , it is just the opposite. We're talking the T-bar adjuster, not the nut down at the bottom some other seats have. Are all the manuals wrong or did I get the two tractors they put together backwards at the factory? I lubed the bolt up and turned it left and it is a two finger deal now and about half way the length of the bolt and it holds my 190# up high like it's sposed to. Common sense and the manual are BOTH wrong in this case. Left (cc) increases tension! This is the "Agri King Seat" w/arm rests and backrest.
Might explain why all of them I've sat in , the adjuster is stone tight and the seat goes to the floor. Another headache explained. Normally common sense will prevail when the manual is in question, but common sense even says to the right , clockwise , tightens/increases/adds or whatever you want to say.
 
How about that, tonight, after the last bale was spun, I started taking my 1070 seat out. Same issue, I weigh 190, the seat goes to the floor and bounces you around like a paddle ball toy. Weight adj is jammed tight, the seat back adj is jammed tight and the swivel is jammed tight. Tractor has a cab and spent it's evenings indoors over the years......Shouldn't be rusty. Perhaps I don't have to get the hot wrench out and get serious......
 
case should a designed their tractors for standing operators ,, a brand new seat is shot in 2000 hours of use...they really have wore themselves out trying to come up with a comfortable seat for the 30 and 70 series ,Case must a hired some folxs from GM, and they were at one time good comfortable seats,, but by the time they make it to my farm someone has pauladean rigged them with a ugly stick ..
 
I can't defend misprinting info in the manuals, but I don't think any manufactures are doing any bragging about seats they built in the 60-70's. The life of the suspensions depended on weight of the operator and roughness of ground the tractors operated on. I am still using a few tractors with this factory suspension and at 40 yr. old they leave a lot to be desired. My 70 series tractors I use for long hrs. I have installed newer air seats in and they are worth every dime they cost for better comfort. Rod.
 
What brand of air seat did you end up with? That's the conclusion I, too, came up with. I know they work, and work well. I think that's the way I'm going to go rather than spending one more nickel on upholstery or suspension work
 
I got a couple from the CASE IH dealer about 10 yr ago and have since become a K+M Dealer and that is where the last one came from. Rod.
 
should be able to just turn it counter clockwise after breaking the jamb loose and it will come right up tight and high.
