Power & Performance
This is a human-powered reel mower, so cutting performance depends directly on walking pace and grass condition. The 5-blade reel delivers a clean, scissor-like cut that's actually gentler on grass than rotary blades, promoting healthier lawn growth.
Working efficiency is best on fine-bladed grasses (like Kentucky bluegrass or fescue) kept at a regular height , it won't power through thick St. Augustine or overgrown turf.
Cutting System
The 12-inch steel cutting deck houses a 5-blade reel that cuts with a shearing action across the full cutting width. Cutting height is adjustable from 0.47 to 1.77 inches via individual wheel height settings, giving you solid range for everything from a tight putting-green trim to a taller, drought-resistant cut.
Clippings discharge into the included rear grass catcher and collection bag, keeping your lawn clean without the need for raking.
Drive & Handling
At just 15.1 lbs, this is one of the lightest mowers in any category , the low weight and compact 12-inch footprint make it highly maneuverable around garden beds, tight corners, and obstacles. There is no self-propelled drive; forward motion is entirely user-powered, which is effortless on flat ground but adds strain on inclines.
The handle is designed for a comfortable grip during typical mowing sessions on small, flat areas.
Battery / Fuel
As a manual reel mower, there is no battery, no fuel tank, and no motor of any kind. The only ongoing maintenance required is occasional blade sharpening to keep the reel cutting cleanly , typically once per season for light residential use.
This makes it one of the most low-maintenance lawn tools available, with no oil changes, spark plugs, air filters, or charging cycles to manage.
Who Is This Mower For?
Ideal For
- ✓ Small yard homeowners (under 2,000 sq ft of flat lawn) who want a quick, low-effort mow without starting an engine
- ✓ Eco-conscious users prioritizing zero emissions, zero noise, and zero fuel cost in their lawn care routine
- ✓ Apartment dwellers, renters, or condo owners with small grass strips or garden areas where compact storage (12-inch deck, 15.1 lbs) is a priority
- ✓ Low-maintenance seekers who want to avoid engine tune-ups, oil changes, and battery replacements , blade sharpening is the only upkeep needed
Not Ideal For
- ✕ Homeowners with hilly or uneven terrain , reel mowers struggle on slopes and can scalp uneven ground
- ✕ Large yard owners , the 12-inch cutting width significantly reduces working efficiency on lawns over 2,000 sq ft, making mowing sessions long and tiring
- ✕ Those with thick, tall, or infrequently mowed grass , reel mowers require grass to be kept regularly trimmed and perform poorly on overgrown or coarse turf
Assembly is required out of the box, but given the mower's simple mechanical design with no engine or motor components, setup is straightforward and typically takes under 20 minutes. The lightweight frame and minimal part count keep the process manageable for most users.
Before first use, check that all wheel axle bolts are snug , loose wheels can affect cutting height consistency across the deck
Set your desired cutting height via the individual wheel adjusters before mowing, and confirm all four wheels are at the same setting for an even cut

FAQ
What size yard is this reel mower suitable for?
This mower is best suited for small yards up to approximately 1,500-2,000 square feet of flat, regularly maintained lawn. The 12-inch cutting width means more passes are required to cover a given area compared to wider rotary mowers, so working efficiency drops significantly on larger properties.
For a small urban lawn, garden strip, or compact backyard, it's a great fit.
How does the cutting height adjustment work?
The cutting height is adjusted via individual wheel height settings on each of the four wheels. The range spans from 0.47 inches (a very tight trim) up to 1.77 inches (a taller, more relaxed cut).
Make sure all four wheels are set to the same height before mowing to ensure a level cut across the full 12-inch cutting width.
Is this mower hard to push?
On flat ground with regularly mowed grass, the 15.1 lb frame is easy to push and requires minimal effort , many users find it lighter work than a heavy rotary mower. Resistance increases noticeably with taller or thicker grass, and slopes add significant strain since there is no self-propelled drive.
Keeping your lawn trimmed regularly is the key to effortless operation.
Does this mower bag the clippings or mulch them?
This mower includes a rear-mounted grass catcher and collection bag that captures clippings as you mow, discharging them to the rear. This keeps your lawn tidy after each pass without needing to rake.
There is no mulching or side-discharge option on this model.
How does a 5-blade reel compare to a 3-blade reel?
More blades generally means more cuts per revolution, resulting in a finer, cleaner cut and a smoother finish , similar to the difference between a fine-toothed comb and a coarse one. The 5-blade reel on this mower is well-suited for fine-textured grasses and delivers a quality cut that's gentler on grass health than rotary blade impact cutting.
For typical residential lawns kept at regular heights, 5 blades hit a good balance of cut quality and ease of push.
How much maintenance does this reel mower require?
Very little , that's one of its biggest advantages. With no engine, motor, or battery, there are no oil changes, spark plug replacements, or charging cycles.
The main periodic task is blade sharpening to maintain cut quality, typically needed once a season for light use. Wiping the blades clean and keeping the reel free of debris after mowing will extend blade life further.
Bottom Line
The sertheha 12-inch 5-blade push reel mower is a solid, no-frills choice for eco-conscious homeowners with small, flat lawns who want to eliminate fuel investment, noise, and engine maintenance entirely. Its 15.1 lb frame, zero-emissions operation, and included collection bag make it a practical tool for regular light-duty mowing.
Those with larger yards, slopes, or thick grass will find its 12-inch cutting width and manual operation too limiting.
Best for small, flat lawns under 2,000 sq ft where quiet, emission-free, low-maintenance mowing is the priority.
Consider alternatives if your yard has slopes, thick or coarse grass, or exceeds 2,000 sq ft , a wider electric or self-propelled mower will save significant time and effort.
