96045002100, YTH21K46 specifications

The Husqvarna YTH21K46 is a robust and efficient riding mower, designed for homeowners who demand reliability, performance, and ease of use in maintaining their lawns. Powered by a strong 21.5 HP Kohler engine, this riding mower provides ample power to tackle various mowing conditions while ensuring durability and long-lasting performance.

One of the standout features of the YTH21K46 is its 46-inch cutting deck. This deck allows for efficient mowing of medium to large-sized lawns, covering more ground in fewer passes. The cutting height can be easily adjusted via a rugged lever, offering six different positions ranging from 1 to 4 inches. This versatility enables users to achieve the desired lawn appearance while accommodating different grass types and seasonal conditions.

An important technological feature included in this model is the ReadyStart system, which allows for easy engine start-up without the need to prime, enhancing user convenience. This, combined with the smooth hydrostatic transmission, provides seamless acceleration and deceleration, making it simple to navigate around obstacles and tight spaces. The steering wheel is ergonomically designed, ensuring comfort and ease of control during operation.

The Husqvarna YTH21K46 also boasts a comfortable and spacious operator's platform, which includes an adjustable seat to accommodate different user heights, promoting an enjoyable mowing experience. The optimized design creates an ideal driving position, reducing fatigue during extended use. Moreover, a front-mounted bumper adds protection and enhances the thermal efficiency of the mower.

In addition to its cutting capabilities, this riding mower is designed with functionality in mind. The integrated LED headlights improve visibility during early morning or late evening mowing sessions. A washout port makes it easy to clean the cutting deck, ensuring optimal performance and longevity.

Lastly, the YTH21K46 supports various attachments and accessories, including mulching kits, baggers, and snow blades, expanding its versatility for year-round lawn care. This adaptability means it's not just a seasonal mower; it serves as a multifunctional tool to help maintain your property in every season.
