case 190

my father left me a case 190 with a loader on motor runs fine, loader works . it just does not move forward or backwards. removed the cover on the axle stared up and shifted into gear all gears worked forward and backward what should I look for? both axles broke or a bad diff?

Is the loader powered by a separate pump that runs off of the PTO clutch pulley on the front of the Kohler? If so, then it may well be that you have a Lovejoy coupler problem. The hydraulic pump for the tractor itself is connected to the output shaft of the Kohler via a JAW-TYPE coupler that has a rubber cushion in the middle of it to prevent metal to metal contact.

Over time, the rubber cushion (known as a spider) hardens and then slowly disintegrates. Once it is gone, the metal jaws of the coupler halves contact one another and destroy themselves to the point where the pump will no longer spin. If the pump does not spin, then you have no hydraulic power to spin the hydraulic motor that is mounted on the left side of the trans-axle.

However, the 180, 190 and 195 models are well known for soft axle shafts that will twist and then shear off right where the splined ends enter the differential carrier. It only takes one shaft to snap and the tractor goes no where.

If you have the top cover off of the trans-axle and nothing rotates when you have the engine running and the travel lever pushed forward, then you probably have a coupler problem. If you do get gear rotation, then the problem is a snapped axle shaft. The opposite side is probably damaged as well.

Loaders on these tractors is a bad idea. They were never designed for loader service. Used 190 axle shafts that are in good condition are hard to find. You may have to find a pair of axle shafts from a 150 and have a machine shop remove the axle flange plates from both sets so they can be swapped over to get the correct bolt pattern.

If you can see the gears turning, something else is slipping.

I am not familiar with that model, but first thing I would do would be have a helper check to see if one of the axles is turning inside the wheel hub. (Usually one guy has to be in the seat.) Its a common thing for mowers that have wheel keyed to the axle to lose the key when a rear tire is repaired.

As you said, you are not familiar with that model.

Case garden tractors all use wheel rims that bolt on with either 5 or 6 lugs. There are no keys to get lost.
