Instructions On Testing And Adjusting The Drive Control In Your Two Stage Snow Blower. If you’ve got a Cub Cadet two stage snow blower, and the machine’s drive control has not been correctly adjusted, then it may lead the disengagement of the machine while you’re using it. First of all, you need to do a number of tests to ensure that you know whether your drive cable needs adjustment or not. We’ll show you just how to test that. You need to release and disengage the snow blower’s drive control and let the cable slack a little.. If the drive randomly disengages while you’re using it or if there is too much slack in the drive cable, then that may mean that you’ve got to adjust the cable.. Gently push the snow blower forward while the drive control is released and you should see that it rolls freely.. Now, engage the drive control and gently push the equipment forward. The wheels should not turn and the machine shouldn’t be able to roll freely.. Release the machine’s drive control.. Finally, move the shifting lever back and forth between R2 and F6 a few times, to ensure there is no resistance while you are shifting it.. If there are any failures in any of the steps above, then you may just have to adjust your snow blower’s drive control. We’ll show you some of the steps you need to take in order to do just that. – First, turn the engine off – Now, loosen the lower hex screw on the drive cable bracket – Slacken the cable by moving the bracket up, or tighten the cable by moving the bracket down. – You can now tighten the lower hex screw once the bracket is in its desired position. – Finally, try out a final series of tests to make sure that you don’t need to make any more adjustments.
