Note to self: Please check that your centre hole pattern matches before purchase to avoid installation problems
• Aerodynamic Blades: The blades are designed with many curves to create a strong airflow as they cut, which propels the grass in a continuous cutting cycle, eventually turning it into finely chopped grass (50% more bagging capacity). This not only greatly increases the efficiency of cutting and returning the chopped grass to the soil as a nutrient, but also greatly reduces the risk of blade clogging
• Suitable for Tough Mowing: The blades are made from high-strength steel that has undergone advanced heat treatment to give the blades maximum hardness and durability, making them ideal for cutting weeds or clearing uneven terrain. The finished lawn cut with the blade is as neat and even as if it had been cut individually with scissors
• Excellent Performance: We subject our blades to a rigorous series of tests, including dynamic balance tests, Rockwell hardness tests, V-bend tests, blade chip tests, performance tests and field tests. The blade is also coated with paint (which wears off as you mow) for extra corrosion protection and to protect your hands during installation. All to make it your right hand man!
