How to Keep the Mower Deck Belt Long Lasting?
The deck belt is a unit of the mower that will perform till the last of its efficiency or until it is not damaged. But, each of us wants it to be longer than average.
Well, when I replaced a new deck belt, I applied some ideas and guess what, they truly worked. That’s why I am describing them below to help you.
So, why don’t we know them one by one?
1. Avoid Lengthy Grasses
Lengthy grasses tend to take more time to be cut and noticeably, they are difficult to cut at once. As a result, the mower and its deck belt undergo extra pressure.
It can cause the deck belt to wear out or weaken gradually. Therefore, if the grasses of your garden or lawn have not been cut for a longer period, use a weed whacker.
It will cut the super long grasses and make it simple for the mower to do its job.
2. Adjust the Belt Keeper Properly
Belt keepers are aside the pulleys that help the belt to be in the correct position. But, as the belt and the mower move with the engine, these belt keepers can be bent.
In my opinion, you can inspect the belt keepers twice or thrice a month to avoid their bending. Adjust them if needed. Thus, the belt won’t move towards injury so easily.
3. Inspect the Pulleys
The deck belt surrounds the pulleys in the deck and therefore, they play a significant role in keeping the belt safe and sound.
Over time, the pulleys can get jammed or weakened or carry rough edges. These will deteriorate the condition of the belt.
To avoid these, you can inspect the pulleys while checking the belt keepers. I suggest greasing them to get rid of these issues. Hopefully, the belt will be alright for a better duration.
4. Reduce Excessive Stretching
Excessive stretching of the deck belt is a way to invite its expiry date earlier. Besides, the belt will carry worn signs in it to let you know that it is going to be damaged soon.
Therefore, you will have to keep an eye if the belt is facing excessive stretching issues. You can find it by checking if the belt is loosened or not.
The deck belt can stay alright and do its task for an extended duration if you can balance its stretching.
5. Regular Maintenance
Last but the easiest way to expand the lifespan of the mower deck belt is regular maintenance. In this respect, you can clean the belt using a clean cloth after running the mower twice or thrice.
Cleaning keeps dust and dirt away and the belt remains free clogging. Moreover, you can check if the belt is positioned too tightly or too loosely.
Thus, your regular inspection will keep the deck belt safe and sound. Being free from interferences, the lifespan of the deck belt will be improved.
