Sun Joe Mower Specs Compared

Cutting Width

Edge: Sun Joe 20-Inch Push Reel Mower with Grass Catcher

The Sun Joe 20-Inch Push Reel Mower with Grass Catcher offers a 20-inch cutting path. This wider deck covers more ground per pass than the Sun Joe 15-Inch 24V Cordless Reel Mower, which features a 15-inch cutting width. If you have a larger lawn and want to reduce the number of passes required, the 20-inch model provides better efficiency. The narrower 15-inch mower may be easier to maneuver in tight spaces or around obstacles, but it requires more time to cover the same area. You should choose based on your lawn size and the need for speed versus maneuverability.

Power Source

Edge: Tie

These mowers use completely different power sources. The Sun Joe 20-Inch model is a manual push reel mower. It relies entirely on your physical effort to push the mower and turn the blades. There is no battery or motor involved. The Sun Joe 15-Inch 24V Cordless Reel Mower uses a 24-volt cordless battery system with a 360-watt motor. This motor drives the blades, reducing the physical effort needed to cut grass. However, you must own or purchase a compatible 24V battery and charger separately. The cordless option offers powered assistance, while the manual option requires no electricity.

Cutting Height

Edge: Sun Joe 20-Inch Push Reel Mower with Grass Catcher

Adjustment options differ between the two models. The Sun Joe 20-Inch Push Reel Mower with Grass Catcher provides nine positions for cutting height adjustment, allowing you to set the height up to 2.44 inches. This gives you fine control over your lawn's appearance. The Sun Joe 15-Inch 24V Cordless Reel Mower offers only four manual positions: 0.6 inches, 1.0 inches, 1.5 inches, and 2.0 inches. While the 20-inch model allows for a higher maximum cut, the 15-inch model covers a similar range. You should check your preferred grass type and maintenance style to decide which adjustment range suits you better.

Grass Collection

Edge: Sun Joe 15-Inch 24V Cordless Reel Mower

Both mowers include a rear collection bag to catch clippings. The Sun Joe 20-Inch model comes with an 8.5-gallon grass catcher. The Sun Joe 15-Inch 24V Cordless Reel Mower includes a larger 11.9-gallon bag. The larger capacity on the cordless model means you may need to empty it less frequently during mowing sessions. This can be convenient for larger areas. However, the 20-inch mower covers more width, so it might produce more clippings per minute. You should consider how often you are willing to stop and empty the bag versus the width of your cuts.

Weight and Size

Edge: Tie

The physical dimensions and weight vary slightly. The Sun Joe 20-Inch Push Reel Mower with Grass Catcher weighs 30 pounds and measures 26.6 inches in width, 50.4 inches in height, and 48 inches in length. The Sun Joe 15-Inch 24V Cordless Reel Mower weighs 31.8 pounds. Its dimensions are smaller, measuring 18 inches in width, 15 inches in height, and 22 inches in length. The cordless model is more compact for storage but slightly heavier. The manual model is lighter but bulkier. You should measure your storage space and consider which size is easier to handle and store in your garage or shed.

Frequently asked questions

Which Sun Joe mower is better for large lawns?

The Sun Joe 20-Inch Push Reel Mower is the better choice for larger areas. Its 20-inch cutting width covers significantly more ground per pass than the 15-inch model. This wider deck reduces the number of passes needed to complete the job, saving time despite the manual effort required.

Does the 24V model come with a battery?

No, the Sun Joe 15-Inch 24V Cordless Reel Mower is sold as a tool-only unit. The specifications list the included battery as tool only, meaning you must purchase the battery and charger separately. It is designed for users who already own compatible 24-volt batteries from the same brand.

How heavy is each reel mower?

The manual 20-inch model weighs 30 pounds, while the cordless 15-inch version weighs 31.8 pounds. Both are relatively lightweight for their class, making them easy to maneuver. The slight weight difference in the cordless model accounts for its motor and internal components compared to the purely manual design.

Can both models bag clippings?

Yes, both mowers support bagging. The Sun Joe 20-Inch Push Reel Mower includes a grass catcher for collecting clippings. The Sun Joe 15-Inch 24V Cordless Reel Mower also features a grass catcher. This allows you to maintain a tidy lawn by removing cut grass instead of leaving it on the surface.

Is the cordless mower quieter than the manual one?

The cordless model operates using an electric motor, which is generally quieter than gas engines. However, the manual 20-inch model produces no motor noise at all, relying entirely on your physical pushing power. Both are significantly quieter than gas-powered alternatives, making them suitable for noise-sensitive neighborhoods.

What are the dimensions of the 20-inch mower?

The Sun Joe 20-Inch Push Reel Mower measures 26.6 inches in width, 50.4 inches in height, and 48 inches in length. These dimensions allow it to fit in most standard garages. The larger footprint accommodates its wider cutting deck and grass catcher system compared to the more compact 15-inch model.

Do I need to charge the manual mower?

No, the Sun Joe 20-Inch Push Reel Mower requires no charging. It is powered entirely by manual effort, meaning you push it to engage the reels. This eliminates the need for batteries or electricity, making it a zero-emission option that is always ready to use without waiting for a charge.
