Function & Purpose

The MIA13031 Primary Transmission Pulley is a core component of the transmission system in John Deere lawn tractors, specifically designed for the 100-series models including D105, E100, X105, and X106.

Primary Functions

This part's essential role is to transfer power between the engine and transmission while enabling continuously variable speed control:
  1. Power Transmission: Acting as the "drive pulley" in the drivetrain, it transfers rotary power from the engine via a belt to the transmission's secondary (driven) pulley, ultimately propelling the wheels.
  2. Speed Regulation: Working in conjunction with the RT400 General Transmission, it precisely adjusts the gear ratio by altering the belt's contact diameter within the pulley groove. This ensures efficient power delivery to the drive wheels and enables smooth speed changes.
  3. Torque Sensing: Within the CVT (Continuously Variable Transmission) system, this pulley automatically adjusts the speed ratio in response to load variations, maintaining the engine in its optimal RPM range.

Technical Specifications

  • Compatible Models: D105, E100, X105, X106, and other John Deere 100-series lawn tractors
  • Transmission Match: RT400 General Transmission (replaces AUC11077, AUC10266, MIA13114, etc.)
  • Material: Metal construction featuring lightweight, rust-resistant, and durable properties
  • Product Type: Aftermarket replacement part, direct replacement installation

Operating Principle

In the CVT drivetrain, this drive pulley connects to the driven pulley (typically part number MIA12481) via a belt. As engine RPM changes, the pulley's movable conical discs adjust the groove width under centrifugal force, forcing the belt to ride higher or lower. This changes the effective drive diameter, achieving continuously variable transmission. This design allows the mower to automatically adjust ground speed based on terrain and load without traditional gear shifting
