The SM 4484 is an industrial-grade Self Starter Rocker Assembly (Brush Holder) designed specifically for the John Deere range of agricultural tractors. Utilizing a heavy-duty Bosch-style (B.TYPE) architecture with a high-torque 4-brush configuration, this assembly is a direct replacement for the original equipment manufacturer (OEM) reference #G70305. It is engineered to provide the massive electrical flow required to crank high-displacement diesel engines in demanding farming environments.
