The Sun Joe Cordless Electric Push Lawn (model 24V-X2-17LM) serves as the brand’s primary rotary walk-behind solution for small to medium residential properties. Built with a 17-inch steel cutting blade, this machine relies on high-speed rotational impact to sever grass blades cleanly in a single pass. At the heart of the deck is a 670-watt brushless motor engineered to run cooler and provide extended operational longevity compared to traditional brushed alternatives. Brushless architecture optimizes battery draw by dynamically adjusting torque under varying grass densities, making this unit a prime candidate if you are searching for the best sun joe cordless mower for general turf maintenance.

Power delivery relies on a dual-battery configuration that pairs two 24-volt 4.0 Ah lithium-ion packs in series to generate a 48-volt operating system. This electrical setup delivers up to 25 minutes of cordless runtime and recharges via an included dual-port charger that replenishes both power cells simultaneously. For operators weighing their options in a sun joe electric lawn mower search, this dual-cell platform provides full rotary capability without the emissions or mechanical maintenance of gas engines. The mower features a single-lever 6-position height adjustment system ranging from 1 inch to 3 inches, allowing precise deck leveling across seasonal grass shifts. Cut grass is channeled into an 11-gallon collection bag equipped with an integrated indicator window to monitor thatch accumulation.

Weighing 33.8 pounds, this machine delivers manageable maneuverability across graded turf without requiring a self-propelled transmission. The 17-inch cutting path strikes an intentional balance between deck coverage and compact storage footprint, fitting through narrow garden gates where wider decks stall. However, the 25-minute runtime ceiling means properties exceeding one-quarter acre will require supplementary battery pairs to complete mowing without operational pauses.

• 670-watt brushless motor engineered for efficient power consumption and reduced heat buildup
• 48-volt dual-battery power supply using two 24-volt 4.0 Ah lithium-ion batteries with a dual-port charger
• 17-inch heavy-duty steel blade paired with a 6-position height adjustment lever ranging from 1 inch to 3 inches
• 11-gallon rear collection bag with built-in fill level indicator window

The Sun Joe Cordless Electric Push Lawn (model 24V-CRLM15) shifts away from rotary impact cutting to utilize a motorized cylinder reel architecture. This unit is built around a 15-inch, 5-blade RAZOREEL cylinder that operates against a stationary bedknife, producing a clean scissor shear rather than tearing the grass tips. Powered by a 360-watt electric motor, the cylinder spins under dedicated motor force, eliminating the heavy pushing resistance typically associated with ground-driven reel units while preserving the clean cut essential for delicate turfgrass varieties such as bentgrass, zoysia, and Bermuda.

This complete kit includes a 24-volt 4.0 Ah lithium-ion battery and charger, integrating seamlessly with the manufacturer’s wider cordless platform. The cutting height on the sun joe 24V-CRLM15 is governed by a 4-position manual adjustment lever that alters the roller geometry to achieve cutting heights between 0.6 inches and 2.0 inches. This specialized low-clearance spectrum is tailored for manicured estates where short, carpet-like grass is maintained. An expansive 11.9-gallon rear collection bag captures the severed blades directly behind the reel, preventing clippings from smothering the turf canopy.

With an operational weight of 33.6 pounds and frame dimensions measuring 22 inches deep by 18 inches wide by 15 inches high, this reel mower remains lightweight and agile across tightly bordered lawns. The scissor-cut mechanism consumes less energy than a wide rotary disc, allowing the 360-watt motor to trim dense patches smoothly. However, because the maximum cut height caps at 2.0 inches, this unit is ill-suited for overgrown paddocks, tall fescue lawns kept above 3 inches, or yards littered with coarse twigs that can bind the 5-blade cylinder.

• 360-watt electric motor driving a 15-inch 5-blade RAZOREEL cutting cylinder
• 4-position mechanical height adjustment system spanning 0.6 inches to 2.0 inches
• Complete cordless kit configuration including one 24-volt 4.0 Ah battery and dedicated charger
• 11.9-gallon high-capacity clipping collection catcher

Best for: Existing Sun Joe 24V battery owners

Pros

• 50-minute runtime potential
• 5-blade scissor reel system
• 360-watt motor power
• 9-gallon rear bag

Cons

• Battery and charger excluded
• Max cutting height of 2.0 inches

The Sun Joe 24V-CRLM15-CT 24-Volt IONMAX Cordless represents the bare-tool iteration of the brand’s motorized reel platform. Shipped without a battery or charger, this model is built specifically for property owners who already operate Sun Joe 24V IONMAX yard tools. Mechanically identical to its kit counterpart, the sun joe 24V-CRLM15-CT incorporates the same robust 360-watt motor to spin its 15-inch, 5-blade RAZOREEL assembly. By isolating the tool from bundled charging accessories, it gives budget-conscious consumers an entry point into motorized reel cutting without paying for redundant lithium-ion cells.

When paired with a standard 24-volt 4.0 Ah IONMAX battery, the unit achieves runtimes up to 50 minutes, capable of grooming up to 4,910 square feet of turf on a single charge. The scissor action shears grass cleanly, reducing moisture loss and brown tip discoloration on premium turf. The height-of-cut system offers 4 manual settings measured at 0.6, 1.0, 1.5, and 2.0 inches. It also includes the standard 11.9-gallon rear collection bag, keeping the lawn surface free of thatch-building clippings. Homeowners maintaining diverse outdoor setups like a sun joe cordless pressure sprayer can swap batteries directly between tools.

At an unboxed weight of 31.8 pounds, the bare-tool chassis is slightly lighter to handle out of the package than bundled setups. The quad-wheel configuration stabilizes the 15-inch cutting deck across undulating contours, preventing scalping at lower height intervals. The primary constraint rests in the power requirement: operators lacking an existing 24V IONMAX battery cannot operate the tool out of the box, making verification of battery compatibility essential before purchase.

• Tool-only bare configuration compatible with all Sun Joe 24V IONMAX lithium-ion batteries
• 360-watt motor capable of covering up to 4,910 square feet per 4.0 Ah charge
• 15-inch 5-blade RAZOREEL cylinder delivering 4 discrete height settings: 0.6, 1.0, 1.5, and 2.0 inches
• Detachable 11.9-gallon rear fabric grass catcher

Best for: Lawns requiring seasonal thatch removal

Pros

• 12-amp electric motor
• Spring steel Airboost tines
• 5-position depth adjustment
• Detachable 8-gallon bag

Cons

• Requires extension cord
• Not a standalone grass mower

The Sun Joe Electric Dethatcher & Scarifier (model AJ801E) is a specialized turf maintenance machine engineered to remove dead thatch, moss, and lateral root mats rather than trim standing grass blades. While often evaluated alongside mowers during spring yard revitalization, the sun joe AJ801E performs an entirely different agronomic role. Driven by a powerful 12-amp corded electric motor, this unit operates across a 12.6-inch wide working path (housed in a 13-inch chassis) to comb through the lower turf canopy and loosen accumulated organic matter that prevents moisture and fertilizer from reaching the root zone.

The system utilizes Airboost technology, deploying spring steel tines that rotate at high velocity to lift embedded thatch efficiently. A 5-position depth adjustment lever allows operators to fine-tune tine penetration, ranging from light surface raking to deeper scarifying that scores the soil surface to encourage root division and enhanced aeration. An 8-gallon collection bag attaches directly to the rear exhaust port to capture lifted debris, streamlining cleanup compared to manual hand-raking. For property owners conducting comprehensive turf overhauls, comparing this model within a broader sun joe scarifier analysis highlights the continuous run capabilities provided by its corded 12-amp powertrain.

Weighing 27 pounds, the AJ801E is exceptionally nimble, allowing operators to make overlapping passes across compacted lawn zones with minimal physical fatigue. The corded electric architecture eliminates battery runtime restrictions, ensuring that demanding dethatching passes across large yards remain uninterrupted. However, because it relies on an external power cord, operators must manage extension cord routing to avoid running over the cable, and it cannot replace a traditional mower for routine weekly blade reduction.

• High-torque 12-amp corded electric motor providing continuous power without battery drainage
• 12.6-inch working width equipped with resilient spring steel tines and Airboost debris pickup
• 5-position mechanical depth control to alternate between light surface dethatching and root scarification
• Includes a detachable 8-gallon collection catcher for mess-free disposal of lawn thatch

Best for: Small yards needing zero emissions

Pros

• 9-position height adjustment
• Zero battery maintenance
• 5 precision steel blades
• Quad wheel traction

Cons

• Requires manual pushing effort
• Grass bag not included

The Sun Joe Manual Push Reel Lawn mower (model MJ503M) provides completely unpowered, human-driven cutting mechanics for quiet, emissions-free lawn grooming. Operating without a battery, motor, or electrical cord, this machine relies on forward pushing momentum to transfer kinetic energy through its quad-wheel geartrain into a 5-blade sharpened steel cylinder. Covering a 14-inch cutting swath, the sun joe MJ503M shears grass against a stationary bedknife with absolute precision, delivering a clean surgical cut that promotes optimal grass health on compact residential properties.

Despite its mechanical simplicity, the MJ503M boasts the widest height versatility among Sun Joe’s reel offerings, featuring a 9-position manual adjustment system that spans from 1.1 inches up to 2.9 inches. This broad mechanical range allows operators to accommodate taller cool-season grass varieties that cannot tolerate the sub-one-inch limits of motorized reel mowers. The chassis rides on all-terrain quad wheels designed to maintain steady ground engagement, preventing cylinder slippage over uneven lawn patches. The ergonomic handle is padded to reduce hand strain during continuous manual pushing.

Weighing 27.5 pounds, this push mower is light enough to carry with one hand and hang on a garage wall hook, making it ideal for urban townhomes, courtyards, and small terraces where storage space is constrained. It requires virtually zero maintenance beyond periodic blade adjustments and seasonal lubrication. However, because it lacks a motorized drive or grass collection catcher, the physical effort required scales directly with lawn height, and cut clippings are deposited directly back onto the turf surface as mulch.

• Completely manual human-powered mechanical drive with zero fuel, oil, or battery requirements
• 14-inch cutting cylinder equipped with 5 durable heat-treated steel blades
• 9-position manual height adjustment system ranging from 1.1 inches to 2.9 inches
• All-terrain quad-wheel assembly paired with an ergonomic padded push handle
