case 610b

going to try start my parts 610 this week. can someone explain how the torque converter part works? I assume no clutch at all, do brakes have to be on to shift into gear? kind of nice to know before I try starting it.

There's a clutch in there, only it has a torque converter attached to it. You have to have the engine set at a dead idle in order to shift into any gear. Once you get in the gear you want release the clutch peddle and increase the engine speed to get the tractor rolling. After you get the tractor moving pull the lever on the right side of the steering wheel down to lock it into direct drive. The direct drive will disconnect when you depress the clutch peddle, or you can raise the lever. To use it to back a wagon, or trailer, you put in reverse, increase engine speed a little, then hold it in place with the brakes. Let up on the brakes to let the tractor move. It's kind of like slipping the clutch to maneuver in reverse only you use the brakes. I hope tis makes sense to you.

so is it a clutch and like my 630 or something completely different? I don't know what is all wrong with this tractor as yet, but hope it at least will run to check the pto and the 3pth. thanks for that info.

An operator manual would explain it better than I could. Below are pages about the Case-O-Matic for the 530. The operation of a 610B should be the same.

Just think of your transmission as an
automatic just like your car, only
there's no "park" position, just
"neutral" when your clutch is
depressed. Your"clutch pedal" if you
follow the linkage is attached to
nothing but a hydraulic valve. The dam
thing is always spinning which is why
you need to idle it down as far as
possible to get it to pop into gear and
it's also why it may jump a bit if you
don't have your foot on the brakes.
Just like your car after you put it in
gear, it may just sit there until you
give it some gas. Once your rolling
you can then put it into direct drive
and it will feel just like a normal
tractor until you step on the pedal
again which automatically shifts it
back into automatic/torque converter
mode. Clear as mud?

The clutch pedalis connected to a dump valve controling converter pressure. When you depress the "inching pedal" the output shaft of the converter stops turning so you can select a gear. Like an auto tranny on a PU you don't start moveing by slaming it into gear at more than an idle. Once you have throttled up the tractor will start moveing and then you can pull the Direct Drive lever down on the dash. That controles a clutch pack that locks the converter solid from the engine flywheel to the converter output shaft. The converter clutch pack can be engaged or disingaged any time to adjust to changing loads or situations.

One thing we all forgot to mention is that the tractor will free wheel going down hill when in C.O.M drive. Make sure your brakes are in good operating order before you start using the tractor.
