The Husqvarna terrain wheel kit (part 597705402) is a dedicated upgrade for owners of IQ robotic mowers, specifically the 410iQ, 420iQ, and 440iQ models. Designed to tackle rough terrain and slopes, this kit addresses a common limitation of standard wheels, making it a valuable addition for those with uneven or hilly lawns.
Standout features include the aggressive tread pattern on the heavy rear wheels, which dramatically improves traction in wet grass and on inclines. The kit also comes with six brushes that help keep the mower deck clean and aid in maneuvering.
