Detailed Description
The LawnMaster CLMF4819X is a thoughtfully packaged electric push mower that focuses on usability. At the heart of the mower is a brushless motor that provides efficient torque at 3,600 RPM while remaining quieter and more durable than brushed motors. The 19-inch cutting deck is ideal for homeowners who want a balance between maneuverability and coverage — large enough to reduce mowing time compared to very small electric mowers, but still compact enough to navigate flower beds and narrow gates.
Included are two 24V 4.0Ah batteries and a dual charger, which is a major advantage if you’re searching for a dual battery mower with fast charger for long runtime. With both batteries installed the mower offers up to about 40 minutes of runtime under typical conditions. The iPOWER system helps optimize battery use, dynamically adjusting power flow to extend run time on lighter tasks.
Practical features include six height settings (1.4″–3.4″), an easy-to-empty grass bag, and the ability to switch between mulching and side discharge. The mower is also relatively lightweight, making it a good choice for lightweight cordless mower for hilly lawns and slopes where portability matters. Because the batteries are removable, maintenance is low — no oil changes, no spark plugs — and you can charge batteries indoors with the dual charger.
Pros and Cons
Pros
- Quiet brushless motor with solid cutting power — ideal for suburban neighborhoods.
- Dual 4.0Ah batteries and dual charger for extended mowing sessions and shorter downtime.
- 6-position cutting mower for greater flexibility in lawn height.
- Low maintenance — no gas, oil, or complex servicing.
- 2-in-1 mulch/side discharge increases versatility.
Cons
- Runtime (~40 minutes) may require a second charge for larger yards (unless you buy spare batteries).
- 19-inch deck is perfect for small-to-medium yards but slower on large properties compared to 20–22 inch decks.
- Battery runtime varies with grass density, slope, and cutting height.
Who Should Buy This Product
Consider the LawnMaster CLMF4819X if you want to order electric push mower technology that’s easy to use, quiet, and low maintenance. This mower is ideal if you need a compact 19 inch brushless cordless mower with two 24V 4.0Ah batteries and dual charger for small-to-medium yards, want to shop 4.0Ah battery mower options, or are looking for a low maintenance cordless mower with removable batteries. If you frequently mow hilly terrain, the lightweight design and brushless motor help, but you may want to consider extra batteries for extended runtime.
Comparison with Similar Products
Compared to other battery powered lawn mower options, the LawnMaster CLMF4819X stands out for including two 4.0Ah batteries and a dual charger out of the box — a package that can be more costly with some competitors. Many 19–20 inch brushless mowers require purchasing spare batteries separately to achieve comparable runtime. In terms of cutting versatility, the 6-position cutting mower feature matches competitors and gives a good range of deck heights. If you’re comparing to larger 21–22 inch battery mowers, those may cut larger areas faster but will be bulkier and sometimes pricier.
Frequently Asked Questions
How long will the two batteries last?
Battery life depends on conditions, but LawnMaster rates the pair for up to ~40 minutes. Expect shorter runtime on tall or thick grass and longer runtime on regular, well-maintained lawns.
Can I buy extra batteries?
Yes — you can purchase cordless mower with dual batteries for sale or individual batteries separately if you need extended runtime for larger properties.
Is this mower suitable for slopes?
The mower is lightweight and manageable for moderate slopes. For very steep terrain, follow safety guidance and consider traction and stability — sometimes a rear-wheel or dedicated hill mower is recommended.
