H204872 Half-pulley JOHN DEERE (Royal Tiger)

H204872 – Outer Half Sheave

Description

The H204872 is an outer half sheave for the feeder house drive variator on John Deere combines. This half sheave works in conjunction with the inner half of the variator pulley to form a variable speed mechanism that converts rotational motion and transmits it through a belt system to the feeder house conveyor. This allows you to maintain the required feed rate from the header to the combine.

The variator half sheave is installed in the feeder house drive assembly and is an important part of the mechanics that ensures smooth and reliable power transmission during conveyor operation.
