LTX 1042 KW Belt Tension
When I engage the PTO the blades turn very slowly or not at all. The deck belt is newly installed. I checked and it is routed properly. Is there a way to adjust the tension on the belt? It seems very loose when engaged. Of course if there is not enough tension on the pulleys it will not turn. Also when PTO is disengaged the lever/handle does not return to the top of the PTO bracket. Stops about 4" from top is this normal?

The heavy spring at the end of the PTO cable is what puts the tension on the belt when you engage the PTO. Check that you have correctly installed the spring in the arm that moves the idller pulley.
With the engine NOT running, engage the PTO and check the belt tension up by the engine pulley. It should not be banjo string tight but not so sloppy you could get it off the pulley if you tried. I have seen where the correct size belt (1/2" x 96") was too loose and acted like yours. I installed a 94.5" or 95" belt and everything worked just fine. I think with as the tractor ages, a combination of cables and belts stretching and spring losing tension causes everything to start slipping. As far as you handle not topping out in the notch, you would find that it WILL top out when the deck is not installed. The reason it doesn't is because the top of the deck contacts the bottom of the tractor frame when the deck is fully raised and that is where the handle stops. |

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
