Positioned to redirect the belt’s path; often include tensioner pulleys. - Drive Belt (Main
Belt): Usually a V-belt, responsible for transmitting power to the transaxles. - Transaxles:
Located at the rear wheels, where the belts connect to drive the wheels. - Blade Belt:
Separate from the drive belt, powering the mower blades, but sometimes sharing pulleys
in integrated diagrams. Interpreting the Diagram The typical routing process is as follows:
1. The engine pulley engages the drive belt directly connected to the transaxle pulleys. 2.
The belt runs over a series of idler pulleys to maintain proper tension and alignment. 3.
The tensioner pulley automatically adjusts to compensate for belt stretch and wear. 4. The
belt wraps around the transaxle pulleys, which translate the belt’s rotational motion into
wheel movement. In the typical Husqvarna Z254F, the belt diagram illustrates a closed
loop path, ensuring continuous power transfer when the engine runs. ---
