Greenworks LM1404 14-inch 40V push mower kit review

A 14-inch cut path for smaller patches

Greenworks identifies LM1404 as its 40V 14-inch cordless push mower kit, SKU 2508202 and internal model MO40B410. The listed carton includes the mower, one 4.0Ah battery, a charger, a grass catcher and an owner's manual. The 14-inch cutting path is the smallest of the two compact Greenworks kits considered here, so it is worth a look when the lawn is broken into narrow strips or small pockets around landscaping. That is a deck-width advantage, not proof that the full machine will clear every gate: Greenworks does not publish assembled dimensions on the page I reviewed. Check the wheels, body and handle in the actual configuration before relying on the cutting-width number for access.

The mower is push-only; the operator supplies forward movement. Its page describes a 2-in-1 mulch-and-bag system and lists a rear catcher. There is no documented side-discharge route for LM1404, so do not select it if leaving clippings through a side chute is essential. The product FAQ describes removing the bag and inserting a mulch plug for mulching. The sales page's included-items list does not name a plug separately, so check the exact package if the plug must be in the box rather than an accessory to obtain later.

Battery and mowing expectations

This SKU includes one 40V 4.0Ah battery and a charger. Greenworks claims up to 45 minutes and up to one-third acre, plus a 120-minute recharge time with the included charger. Those are manufacturer maxima, not test results or promises for a particular yard. Frequent turns, slopes, taller grass and bagging can change the work completed before charging. A narrow deck can reduce the width of each pass, which is helpful in some constrained spaces but may mean more passes over a broad open area. If the lawn is near the stated acreage ceiling, use a conservative plan and keep the claim separate from a guarantee.

The page says this mower accepts Greenworks 40V batteries but notes a specific fit limitation: the 40V 8Ah pack does not let its cover close. Do not treat platform membership as proof every pack fits. Charger model and wattage are not stated, so use the two-hour recharge claim without inventing an electrical rating. The page lists a three-year limited warranty for tool and battery.

Height and weight are not clean deciding numbers

The 14-inch product page says there are five height positions, a useful shared point across its marketing and specification sections. The range is not consistent within that same page: feature copy gives 1¼ to 3⅜ inches, while the specification table lists 1.2 to 3.1 inches. The linked manual does not resolve that conflict because its cover identifies MO40B00 / LMF334 / SKU 2506302, not the exact LM1404 / MO40B410 / SKU 2508202 listing. Do not make a close-cut requirement depend on one of those two conflicting endpoints until Greenworks confirms the correct range for the mower label in your carton.

Weight has a similar limitation. The exact listing gives 43 pounds as product weight but does not say whether that is with a battery, catcher or another package basis. I would not call that the ready-to-mow weight or use it to decide whether one person can safely lift the machine. The model page says the handle folds and that this can save up to 70% of space, but no assembled or folded measurements are given. If storage is exceptionally tight, measure the real mower rather than treating the percentage as a universal footprint.

Read the right manual before maintenance

The “Owner's Manual” currently linked on the LM1404 page is for a different 14-inch Greenworks configuration: its cover names MO40B00, LMF334 and SKU 2506302. The product page, parts listings and exact kit identity instead name MO40B410 and SKU 2508202. That is a genuine documentation mismatch, not a reason to borrow the other model's blade or replacement-part instructions. Greenworks' exact page FAQ does give broad walk-behind advice: stay off slopes above 15 degrees and mow across rather than up and down; mow dry grass; remove the battery before cleaning and keep water off the unit. For assembly, blade service or a model-specific part, obtain the manual that matches the label on the mower and verify compatibility before ordering.

Greenworks' official recall page lists a 2017 40V Twin Force mower under model 25302 and newer Kobalt 24V/48V USB-C battery products; it does not name LM1404 or SKU 2508202 on the page checked. That is an exact-list check, not blanket proof that every tool or battery is free from later safety notices. Keep the product label and battery model together if checking future manufacturer notices.

LM1404 or the 16-inch LM1624?

Choose LM1404 only when its 14-inch cutting path is a meaningful access benefit and the 40V kit fits your equipment plan. The larger 16-inch LM1624 retains push operation, a single 4.0Ah kit battery and mulch/bag capability, but its exact linked manual matches SKU 2540802 and gives a consistent 1¼-to-3⅜-inch height range. LM1624's page has its own acreage and weight-basis discrepancies, so it is not automatically a better fit; it simply has a clearer operator-document bridge. If a verified lowest setting, exact weight, specific battery fit or a side-discharge attachment is non-negotiable, neither mower's marketing shorthand should settle it.

For a routine of regular mowing on dry, reasonably level small-lawn sections, bag or mulch using the documented setup, empty the catcher as needed and store the pack separately in a dry place. If you need powered travel, a wider cutting path, a verified full-machine weight or one-charge capacity proven for your actual grass, move to a different category or gather more model-specific evidence first.
