How to adjusted Cutting Deck Belt Tension

You do not say which size cutting deck you have. I will be writing about the 48", 3 blade cutting deck

The belt on this deck is self tensioned. The tension is provided by a spring attached to a moveable pulley on the deck. When the belt is in place you can manually force this pulley forward/backward and it will release the tension.

If the belt is off track, place the belt back around all the pulleys in the correct path, lastly force this spring loaded pulley forward/backward (depending on your deck, the direction is not important, the tension is) to get the belt around the pulley. If the belt is placed correctly, when you release the spring loaded pulley it will properly tension the belt.

Typically, these belts should not be jumping off. If yours is coming off frequently the belt may be worn. When they wear they get quite a bit longer, then the tension pulley cannot apply the correct tension. Rarely does the tension spring have to be replaced.

The other problem that causes belt jumping is worn spindles and stationary pulleys. The spindles are the most likely to need replacement. You can buy excellent replacements for JD spindles on Amazon for very reasonable prices. The following spindles are super replacement spindles for the 48" deck. They may very well be the same for smaller and larger decks; I have not researched that. Just search Amazon for Silver Streak # 285851.

Black smoke means iots getting too much fuel. This would cause lack of power as well. Check your choke as well as your carburetor.

Multiple fuel filters. One inside tank and an external. Check fuel flow and volume (pressure) at the injectors.

If its an over head cam engine then yes you would have to do the valve timing, if its a push rod engine then no you do not.

The oil inside for the reverser is good? You found that the oil level was correct, the fluid was clean and no further actions were needed? Usually the failure is the clutch pack but that is seen in the fluid. Can you feel or notice that the shift lever is moving into the gear selection correctly? Do you notice, feel or hear that reverse gear is engaged when selected. Do you hear any noises or sounds that weren't there before the failure? Did this failure happen out of the blue or have you noticed reverse acting up for a while now? Please let me know. Good luck.
