B7200 Will Not Shift into 4WD

[Tractor J]

I have a B7200D 4WD tractor. About 3 months ago I shifted it out of 4WD ( no problems doing it) and now when I try to put it in 4WD it will not go. The level will not move at all. There is no noise or sound. What can I do to get it to shaft to 4WD. Thanks

There is a spring loaded detent ball that holds the lever in the 2WD position. This can rust or fill with crud if it isn't moved for period of time and cause the lever to stick. Give the area in the attached pic a shot of penetrating oil and let it sit a tittle before yanking on it.

If that doesn't work, try lifting the front tires off the ground and spin them by hand while someone tries the 4WD lever.

Thank You. I will try it next time I'm at the tractor.
