Big Dog Mower Reviews
Big Dog Mower Co., a division of Excel Industries based in Hesston, Kansas, has carved a niche in the lawn care industry by offering durable, high-performance zero-turn mowers. Often compared to its sister brand, Hustler, Big Dog mowers are designed to deliver top-quality cutting, power, and comfort at a competitive price.
The company emphasizes heavy-duty construction, user-friendly features, and a strong warranty, positioning its products as reliable options for tackling lawns of various sizes. Their lineup includes models like the Alpha, Diablo, Stout, BlackJack, and Trooper, catering to both residential and commercial users.
Key Features of Big Dog Mowers
1. Heavy-Duty Construction
Big Dog mowers are built with welded steel decks, a hallmark of durability that sets them apart from competitors using stamped decks. Models like the Alpha MP and Diablo MP feature reinforced 7-gauge steel decks, designed to withstand rough terrain and heavy use.
This robust construction is particularly appealing to users with large or uneven lawns, as it ensures longevity and resistance to wear.
2. Powerful Engines
Most Big Dog mowers are equipped with reliable engines from trusted brands like Kawasaki, Kohler, and Briggs & Stratton. For instance, the Alpha 42″ model boasts a 24hp Kawasaki engine, while the Diablo MP offers options up to 35hp.
These engines provide ample power for tackling thick grass, slopes, and large properties, with users reporting efficient mowing on acreages up to 9 acres.

The Trooper, a stand-on model, offers a compact design for maneuverability and less operator fatigue.
4. Warranty and Support
One of Big Dog’s standout features is its industry-leading 7-year limited warranty on many models, such as the Alpha MP. This warranty provides peace of mind, though some users have reported challenges with warranty claims, particularly when dealing with distant dealers or service delays.

Should You Buy a Big Dog Mower?
Big Dog mowers offer a compelling combination of durability, power, and user-friendly features, making them a strong contender for both residential and commercial users.
Their welded steel decks, powerful engines, and generous warranty are significant advantages, particularly for those mowing large or challenging properties. The Alpha series is well-suited for homeowners, while the Diablo MP and Trooper cater to professionals needing robust performance.
However, potential buyers should be aware of reported issues with drive belts, safety switches, and warranty service, which may require proactive maintenance or a reliable local dealer.
The uncertainty surrounding the brand’s future, following its acquisition, is another factor to consider, as it could impact parts availability down the line.
For those considering alternatives, Hustler’s Raptor SD offers similar performance at a slightly lower price, while brands like Kubota and Ferris may provide better ride quality for rough terrains. Ultimately, your decision should hinge on your specific needs, budget, and access to a reputable dealer.
