How to choose

The 42-50 in class suits one to two acres of open residential lawn where maneuverability and coverage balance. For properties under one acre or with tight landscaping, narrow gates, or many obstacles, the Up to 42 in Riding Mower offers tighter turning and easier navigation. For properties exceeding two acres, commercial grounds, or operations requiring faster coverage and heavier-duty construction, the 50+ in Riding Mower delivers wider decks and more robust drivetrains.

Frequently asked

What distinguishes the 42-50 in class from smaller riding mowers?

This class offers wider decks (42–46 in) and higher horsepower (17.5–22 hp) for faster coverage of one to two acres, compared to narrower decks and lower power in the Up to 42 in class suited for under one acre.

When does a property require the 50+ in class instead?

Properties over two acres, commercial grounds, or operations demanding heavy-duty construction and faster mowing speeds benefit from the wider decks and more powerful engines in the 50+ in Riding Mower class.

Will a 46 in deck fit through standard residential gates?

Most standard residential gates are 48 inches wide, allowing a 46 in deck to pass with minimal clearance; verify gate width before selecting deck size.
