The Toro 88-6280 Lawn Tractor V-Belt transfers engine power to the transmission or drive system in compatible lawn tractors. This V-belt runs between pulleys and moves as the engine operates. It works by gripping the pulleys and carrying rotational force to drive components that control movement. Proper belt tension ensures smooth operation without slipping. Replacing a worn or stretched belt restores consistent power transfer and reliable tractor performance during use.
