The GA 4521 GTH rotary rake is designed to meet the needs of hay producers who demand improved productivity while increasing their forage quality. This rotary rake produces large, well-formed windrows that promote faster drying, allowing you to harvest your crops at their peak nutritional value with less reliance on the weather.

Maintenance is minimal with its Masterdrive fully enclosed double-reduction, grease-filled gearbox. The simple clevis hitch allows you to quickly hookup and go. Tangential, double curved tine arms provide the ideal position for fast, forward speeds and excellent raking cleanliness. The parallelogram mount of the windrow curtain is always positioned for efficient windrowing and easy maneuvering. Large balloon tires on bogie axles provide superior flotation on uneven ground. Additionally, its tine arms can be removed for a narrow transport width of 6’5”.
