The CAT DG670 is the manual-push version of CAT’s 60V Max residential mower. It combines a 21-inch steel deck, 20-inch cutting swath, brushless motor, TorqLogic load response, and three clipping modes. The standard kit includes one 5.0Ah battery and charger.
Removing self-propelled drive makes the DG670 simpler and somewhat lighter than the DG671, but it remains a substantial mower at roughly 67 pounds. It is most attractive for a flat small-to-medium lawn where the owner wants a steel deck and does not need powered wheels.

21-inch deck versus 20-inch cutting width
CAT and retailers often lead with a 21-inch size because that is the deck width. The CAT technical data for this mower platform gives a 20-inch blade cutting width. That is still a full-size residential swath, but the distinction matters when comparing passes and replacement blades.
The steel deck is heavier than a molded plastic deck and should tolerate normal residential bumps well. Steel also needs care: remove packed clippings after mowing, avoid leaving the deck wet, and store the machine indoors.
TorqLogic and cutting power
TorqLogic automatically raises motor output when blade load increases in dense grass, then reduces power in easier conditions to conserve the battery. This is useful when a lawn has patches of thicker growth, but it cannot compensate for every condition.
For tall grass, use a higher first cut, slow your walking pace, and discharge rather than mulch if the deck begins to clog. Wet grass increases load, clumping, and corrosion risk. A sharp, balanced blade helps both cut quality and runtime.
Battery capacity and runtime planning
The included DG6B5 battery stores 300 watt-hours according to CAT. Retail runtime figures for this mower vary, so we would plan by lawn size and keep a margin instead of relying on one minute claim. A maintained flat lawn around one-quarter acre is a comfortable starting target for one battery.
The dual-port design provides room for an additional CAT 60V pack, useful for larger mowing requirements. Confirm how the battery changeover works on the exact production version and package you are considering. A second 5.0Ah pack doubles the available stored energy but adds substantially to the total cost.
CAT’s official FAQ lists 2.5Ah and 5.0Ah batteries for its 60V outdoor-power system. Both are compatible, but the 5.0Ah pack is the practical choice for a full-size mower. CAT says its standard 5-amp charger can charge a 5.0Ah pack in about 60 minutes; some seller bundles may include a different charger.
Best yard and terrain
The DG670 suits a flat or gently rolling lawn where the user is comfortable pushing a 67-pound mower. Large rear wheels and a well-balanced handle help over ordinary turf, but the lack of propulsion becomes noticeable on slopes and as the bag fills.
For a small yard, the full-width deck reduces mowing passes compared with a 16-inch machine. For a larger yard, battery capacity becomes the limitation. Buyers approaching one-half acre should budget for a second battery or compare a kit with more included energy.
Mulching, bagging, and side discharge
The 3-in-1 deck can mulch, collect clippings in the 2-bushel rear bag, or use the included side-discharge chute. A mulch/bag lever changes the internal path without a separate rear plug, reducing loose parts.
Mulching is best for frequent dry-weather mowing. Bagging keeps paths and beds clean but increases weight and may use more energy. Side discharge handles heavy growth with the least airflow restriction. Remove the battery and safety key before changing accessories or clearing the deck.
Our research method
Our reviews are research-based. We compare official specifications, manuals, warranty terms, owner feedback patterns, current availability, and competing products. Unless we specifically say otherwise, the product has not been personally tested by our editorial team.
DG670 versus DG671
The CAT DG671 adds variable-speed rear-wheel drive and weighs several pounds more. The cutting platform, height range, clipping options, and common 5.0Ah battery package are otherwise closely related.
Choose the DG670 for a flat lawn, lower mechanical complexity, and a lower purchase price. Choose the DG671 for hills, long rows, or reduced pushing effort. Because the self-propel system uses battery energy, the push model can also direct all available energy to the blade.
Other comparable platforms include the Greenworks MO60L516 and WORX WG751.3.

Availability, parts, and warranty
CAT’s current U.S. power-tool site focuses more heavily on its 18V system, while 60V outdoor equipment and parts remain visible through selected retailers and CAT support pages. That makes local battery, blade, bag, charger, and repair availability an important pre-purchase check.
CAT lists a five-year tool warranty and three-year battery warranty for 60V outdoor equipment. Confirm that the seller is authorized and that the warranty applies to your country and marketplace purchase.

Frequently asked questions
Is the CAT DG670 self-propelled?
No. It is a manual-push mower. The DG671 is the self-propelled version.
How wide does it cut?
The deck is 21 inches wide and the blade cuts a 20-inch swath.
How many batteries come with it?
The common DG670 kit includes one 5.0Ah CAT 60V battery. Verify the exact seller bundle.
Can it mulch and side discharge?
Yes. It supports mulching, rear bagging, and side discharge.
Is a second battery worth buying?
It is useful if the included pack does not finish your lawn with reserve. Check the price and availability of the DG6B5 pack before choosing the platform.
Verdict
The CAT DG670 is a strong-cutting push mower with a steel deck, useful height range, and complete clipping options. Its weight and smaller support network are the main drawbacks. It makes the most sense for a flat lawn and a buyer who can verify nearby parts or dependable online support.
