Buying Guide for Cub Cadet Mulching Blades

The benefits you reap from the above mulching blades are only when you have the right blade working for you. 

So, I always pass any blade through my personal buying guide before making my final decision.

This buying guide is my personal checklist I created after experiencing different mulching blades. Below are some checkpoints that you can check to find out which blade is the right fit for your mower.

Length of Mulching Blade

Length is what makes blades rotate ideally under the deck of the mower without interfering with other parts. Lengths can vary from 16 to 22 inches which totally depends on the deck size of the mower.

Width of Mulching Blade

Width also matters as ideal width cut the grass right. It can vary from 2-4 inches. A wider blade can damage the deck or part of the mower, and a thinner blade can result in less mulching of grass.

Shape of Mulching Blade

Shape refers to the curve in the body and edges of the blade. Sharp and uplifted edges of the blade are ideal for mulching operations. The curve part of the blade makes it easy to cut grass and make mulch. More the curve in the body of the blade means better mulching. 

Fitment According to Hole

The blade’s hole must have the diameter and shape according to the shaft of the mower where you will mount it. Blades come with five, six, seven-star and circular types of holes. So, it’s better to check the blade’s hole for proper fitment on the Cub Cadet. 

Number of Blades Required

Each Cub Cadet requires a different set of blades. Usually, two is the best option as you always have a spare if a single blade is needed. If your mower requires more than one blade, you can opt to buy a set of blades according to your budget.

Quality, Durability, and Warranty

The manufacture offers these three aspects. Usually, USA manufacturers are great in this case, and they provide good quality, durability, and warranty on mulching blades. I would say thicker and steel-made blades always prove to be qualitative and durable
