IH 504 TA

What exactly is the TA lever for on this tractor and should I feel a difference when I pull on it ?

When pulling a load and the tractor starts to lug down, you pull that lever to drop it down a gear to help through a tough spot. Yes you should feel a difference, but it might be harder to detect if you are not pulling something, or going up a hill.

If it is out odf adjustment, it will not work correctly. About 1/3 reduction in ratio when back, direct drive when forward. No clutching needed. Move the lever very rapidly between positions, never slowly. If it makes no difference, either way, it needs attention. Find a local mechanic with TA experience. Look in the archives here to get tons of info. Jim

You may not feel a difference creeping around the driveway in 1st at an idle. There's barely a difference at that speed..

However, the difference is more noticeable if you're in 4th gear. Start out in 4th with the TA back. Wind the tractor up and let the TA lever ahead. The tractor should feel like it shifted into a faster gear.

Make sure you have plenty of room when you do that, though... Start off going down the road, unless you live on a busy road...

If you feel no difference, and the tractor continues to move, then you may have a bad TA clutch. The "high" side of the TA is out, technically. It'll probably coast downhill, so watch it and make sure your brakes work!
