Then one toward the front is the Torque Amplifier lever, pull it back to engage the T/A. The one toward the rear is NOT for unhooking implements and it is NOT for setting the depth of the implement. It is the "Traction Control" handle. There should be 4 notches on it. Pull it all he way up to the highest notch for maximum traction control and vice versa. Traction control is a series of mechanical linkages that simply put an upward force on the implement ( = a downward force on the tractor) depending upon how hard the implement is being pulled. The traction control handle adjusts the ratio to which that force is applied. In most conditions, you will probably want to be running it in the second or third notch.

You are correct -- I have a 460 Hi-Utility, bought it to restore, did not use it before disassembly. I got the traction control and Tel-a-depth mixed up -- at least they both have to do with the hitch.

The one in front is the lever for the torque amplifier, which was explained to you yesterday. The one in the rear is the handle/lever to adjust the tel-a-depth control. It is supposed to maintain a constant depth for the fast hitch and return it to that depth after it has been raised, then lowered, so I have read, I have not used one.

Hey does hydraulics have anything to do with the TA?

No. The TA on the 460 is mechanical.

Is it that hard for you to change it out. I think mine doesn't work becuase in 5th gear it barely moves, sometimes it sits and sounds like it is spinning inside. Is there an adjustment on that just like the clutch?

There are adjustments on everything, but nothing could be so out of adjustment that the tractor would not move. Something is worn out or broken inside.

You can try making adjustments, but I doubt if it will help. Both the owner's manual and the I&T shop manual document the very specific adjustment procedure for the clutch and TA. It's a complicated procedure, that if done incorrectly, will leave the tractor in a state where you can't shift it.

You'll likely end up replacing the main clutch and the TA unit. I certainly hope you didn't buy this tractor; you're in deep deep trouble if you did. It doesn't sound like you have the skills or facilities to fix these major problems, and it's going to cost you a fortune to have it done professionally. If you want to learn, I would start with something smaller and simpler to work on, like a Farmall H.

Or you can forget that the lever is there and operate the tractor as if it's a straight 5 speed. We ran a 656 that way for over 4000 hours before the TA was fixed during an over haul. It will be fine if all you're using it for is mowing and other light work.

I just play on pulling a baler with it and moving a little dirt an snow in the winter.

The TA was the first power shift offered on a tractor. It reduced ground speed about 30% without the need to actually clutch and shift. Its intended use was in heavy fieldwork such as plowing. Hit a "hard" spot and pull the TA lever back, when you get back to "regular" ground you push it forward. All without stepping the tractor, lifting the plow, backing up and then shifting to a lower gear. A huge leap forward – or so it seemed.

The mechanical TA had problems due mainly to lack of maintenance and misuse. It needed to be adjusted periodically to account for wear - if not it quickly destroyed itself. When used the shift needed to be fast - some operators tried "easing it" in and that also caused premature failure. Having the TA engaged while "free wheeling" down a hill also caused it to fail. It was a good idea but it wasn't properly implemented by IH. 50 years later the TA is seen as a detriment to an older IH's resale then as a compliment.

If there are no other issues use it like it is and forget it even has a TA lever. You won't need it to bale hay or for blade work.

The lever up by the clutch is the torque amplifier. It doubles your available gears. The back lever is to unhook your fast hitch implements.

Do you actually have a set set of gears or how does it actually work.

It is a planetary drive system located between the engine's master clutch and the transmission input shaft. It allows full load downshifting or upshifting between 2 speeds without clutching or slowing down When the lever is ahead, the TA is running in direct mode, which means that the gears inside the case are stationary, and the entire housing as a whole rotates. In this setting, engine braking will hold the tractor back on hills. When the lever is pulled back, The case is locked in position using a clutch (I think it is a sprag clutch) and the gears inside begin turning, providing a gear reduction. In this setting, the carrier is only held tight in one direction, meaning that the case is only held to keep it from turning from engine torque. When the tractor is going down a hill, the torque from the wheels are now trying to apply torque to the engine, and the clutch slips over and the tractor free-wheels down a hill with no engine braking. If someone pushes the TA forward to get engine braking while it is free-wheeling, it will grenade, throwing parts all over the inside of the torque tube, and disconnecting the engine permanently from the transmission. However if it is used in the proper manner, it will last a pretty long time. My grandpa had a 340 and a 460 with TA's. Both left with the same TA installed 20 years later. On the other hand I've heard some TA's lasting only a couple years. It all depends on adjustment, and how it was used.

Chad, thanks for the info. With the TA engage do you skip using the main clutch and then it uses the TA clutch? I was looking around today on the tractor and down by the voltage regulator on the trans there is a plate with 4 bolts. I took it off to see what it was and it looked like a clutch. When the tractor is running , not in gear, with the clucth out it spins, push the clutch in it stops. Let the clutch out and pull the TA is also stops. Does that make sense? I just wondered. Also could you tell me where to drain the trans hydraulic fluid and where to check it and fill it. Also fill it how much. Wish my service manual would hurry and get here.

The TA is an extra gearbox that sits between the engine and transmission. It's very similar in design to a car's automatic transmission, except that the complicated valve system that does the shifting in a car is replaced with a lever so it can be shifted manually.

Kind of the same as a 2 speed rearend in a truck?
