Boron vs spring steel rotavator blades — dealer guide
L, C, J & LJF types plus what to verify when comparing imported spring-steel brands with 30MnCrB5 boron blades.
Good blades start with good steel — 30MnCrB5 boron steel, even heat treatment, and sizes you can check.
Use 48–52 HRC hardness and change blades in matching sets. This saves fuel and protects the gearbox.
BHUMI KING ITALY and OSCAR cover rotavator, super seeder, gyrovator, weeder, stubble shaver, cultivator sets and Sangaria phalla — all made in Mandi Gobindgarh.
