5 reasons to buy

  • The single lever height adjustment in the Cat DG671 is praised for its ease of use, making it convenient to change the cutting height quickly. (7 reviews)

    • “The single lever height adjustment is FANTASTIC! I’ve got a couple of places in my lawn that I cut extra short due to some high-quality turf, and it’s wonderful to easily pop the deck up & down. I literally used to use two mowers to save the time and headache.”

    • “Convenient height adjustment will allow one to quickly make multiple cuts in areas of tall grass.”

    • “I love the 7 height adjustments that are done with one touch lever.”

    • “Adjusting the height of the mowing deck is very easy. A single spring loaded lever requires almost no effort to adjust.”

    • “Easy to Adjust the blade height by pushing a handle.”

    • “The blade adjustment is straightforward and convenient.”

    • “the feature for raising and lowering the cutting height is awesome. You pull lever it raises upper down with a spring loaded suspension. It is really slick.”

  • The mower uses a push-button start, making it easier to start without the physical effort required for a pull cord, especially appreciated by seniors. (4 reviews)

    • “No hurting your shoulders and arms pulling and snatching on a cord to start it up.”

    • “Push a button to start, no more pull cords and for me just about tearing out my shoulders.”

    • “The battery had a charge, simply push a button to start.”

    • “After pressing and holding the start button and pulling the handle back, I was able to begin mowing the lawn.”

  • The mower has a folding feature that's easy to use, making it simpler to store and maintain, such as when sharpening the blades. (3 reviews)

    • “The folding function is really easy to execute & handy for touching up the blade. I hit mine with a stone after every mow and so far have only had to hammer & file out one rolled spot where I hit something solid. You should probably get a second blade.”

    • “The handles also adjust and fold down very easily and the entire mower can be stored upright.”

    • “While storing the lawnmower, I fold the handle back over the mower and lean it against the wall; this is incredibly simple and efficient.”

  • The battery system is compatible with other tools like the blower, saw, and trimmer, allowing for easy battery changes between devices. (1 review)

    • “I have two, and two chargers, plus the blower, saw, and trimmer. You only need two batteries across all tools unless you do this for a living and bare tools are available for a significant discount.”

  • The Cat DG671 mower comes with a headlight, which is recognized as a great feature. (1 review)

3 reasons not to buy

  • The battery of the Cat DG671 often needs to be recharged after just 30 minutes of use. (2 reviews)

    • “battery lasted 30 min, needed to be recharged.”

    • “This only mows 20-30 minutes on average grass.”

  • The blade is very light duty and isn't meant for cutting through debris like sticks and rocks. (1 review)

    • “Blade speed must be phenomenal. Speaking of the blade… it’s super light duty. This is not the blade for eating sticks, stumps, baseballs & rocks.”

  • The mower does not perform well in long grass. (1 review)

    • “Did not do well in long grass. Clogged side discharge chute, caused high battery draw.”

Bottom Line

The Cat DG671 is a user-friendly lawn mower. It features a single lever height adjustment for quick, easy cutting height changes and a push-button start, eliminating the hassle of pull cords. Its foldable design simplifies storage and maintenance, and the battery is compatible with other tools like blowers and trimmers. It also includes a handy headlight for better visibility. However, the battery lasts only 30 minutes, and the mower struggles with long grass and debris.
