mykleh...... I wasn't trying to imply it wouldn't move at idle as mine clearly does. My issue is both axles not providing torque at idle.
Jabonee.......I believe you are right. I did another test this evening. I used a strap and connected the TC to a tree, once the strap was tight I revved the engine and slowly added pedal. Only the front tires spun proving the rear axle is still not supplying enough torque to spin them. I thought about what you said regarding axle matching. I had previously read there was often a problem with the B model TC where one axle would drag (I'm not having this problem). In several instances Bobcat would turn the axle matching off and this would fix the problem. Since I recently purchased this vehicle I don't know anything about its history. Since it isn't throwing a code I assume the axle matching has been turned off. This leads me to your other thought about the pump needing calibration. I read in the service manual where this is accomplished with software. It also mentions that all 4 wheels will rotate when this calibration is performed and the vehicle is on jack stands. I have proven to myself that some torque is getting to the rear wheels just not enough to cause them to spin under a heavy load. My current plan is to take the vehicle to the dealer and have them calibrate the pump. I'm guessing they will also be able to tell if the axle matching has been turned off. Thanks for the ideas.
