Benefits of technology
The system ensures a controlled and gradual engagement of the clutch pulley with the drive belt, reducing the risk of belt damage and maintaining optimal tension, thereby enhancing the reliability and longevity of the belt system.
Problems solved by technology
Depending on the number of pulleys or the inertia of the blades attached to the pulleys, engaging the drive belt when the engine is running may prove to be difficult.
One drawback to the prior art direct engagement systems is the lack of a gradual engagement process.
Some of the prior art direct engagement systems slam into the drive belt with tremendous force when activated.
If the engine is turning at a high rate of speed, the belt could slip, stretch permanently or potentially break when the clutch pulley is slammed into the drive belt.
In addition, if the belt stretches over time, the prior art engagement systems may not be easily adjusted to keep the clutch pulley engaged with the appropriate amount of tension.

A gradual engagement system for use in power equipment is herein described. The gradual engagement system causes a clutch pulley to rotate around a clutch arm when an engagement tensile force is applied by an engagement spring. The engagement spring is attached to a pivot arm which is also connected to the clutch arm. The gradual engagement system allows the clutch arm to be pressed against a drive belt in a gradual fashion, providing for a smooth engagement of the various components of the power equipment.

The copyright owner has no objection to the reproduction by anyone of the patent document or the patent disclosure as it appears in the Patent and Trademark Office patent files or records, but otherwise reserves all copyright rights whatsoever.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to motorized power equipment and more specifically to motorized power equipment having an enhanced belt engagement system.[0004]2. Description of Related Art[0005]Power equipment such as lawn mowers, snow blowers, and the like typically use a belt or series of belts to power the equipment. A riding lawn mower may have a drive belt connected to the output shaft of a gasoline engine as well as a hydraulic drive system. The hydraulic drive system may in turn drive a propulsion system which moves the mower in either a forward or reve...
