Sun Joe MJ403E Mow Joe 17-Inch 13-Amp El vs BILT HARD 15" Corded Electric Lawn Mower
Quick Verdict
The Sun Joe MJ403E is the better choice for larger, more established lawns with thicker grass, thanks to its wider 17-inch cutting deck and more powerful 13-amp motor. The BILT HARD 15-inch mower is a strong budget option for smaller, well-maintained lawns, offering excellent value at roughly half the price. For most homeowners with typical suburban yards, the Sun Joe provides a noticeable performance advantage, but the BILT HARD wins on affordability and portability.

Where Sun Joe Wins
Cutting width and efficiency. The 17-inch deck is 13% wider than the BILT HARD’s 15-inch deck, meaning fewer passes to cover the same area. For a 1/4-acre lot, this can save 15–20 minutes per mowing session.
More power for tough conditions. The 13-amp motor delivers greater torque than the 11-amp unit in the BILT HARD. This translates to better performance in thick, damp, or overgrown grass. The Sun Joe also handles light mulching tasks more effectively, as its motor doesn’t bog down as easily under heavy loads.
Higher user confidence. With over 1,200 reviews and a 4.0-star average, the Sun Joe has a proven track record. Its reliability is well-documented across many different lawn types and climates. The included mulching capability adds versatility without needing a separate bagging attachment.
Where BILT Wins
Price and value. At $109.99, the BILT HARD costs less than half the Sun Joe. For budget-conscious buyers or those with small yards, this is a compelling deal. You get a functional corded electric mower without the premium price tag.
Lightweight and maneuverability. The BILT HARD’s smaller 15-inch deck and likely lighter overall weight (though not specified, smaller mowers are generally easier to push) make it ideal for tight spaces, narrow gates, and small gardens. The 3,300 RPM spindle speed is competitive and helps produce a clean cut on regular grass.
Excellent user rating. A 4.7-star average from 65 reviews suggests very high satisfaction among owners. While the sample size is smaller, the rating indicates that buyers who chose this mower are consistently pleased with its performance for their needs.
Which Should You Buy
Choose the Sun Joe MJ403E if: You have a lawn larger than 1/8 acre, your grass gets thick or grows fast, or you value a wider cutting path to finish mowing faster. The extra $120 buys you more power, more deck coverage, and a proven design that handles tougher conditions.
Choose the BILT HARD 15-inch if: Your yard is small (under 1/8 acre), you’re on a tight budget, or you need a lightweight mower for easy storage and maneuvering. It’s an excellent value for occasional use on well-maintained grass.
For most buyers, the Sun Joe is the better investment if you plan to keep the mower for several years. The BILT HARD is a smart choice for renters, small-space owners, or as a backup mower. Both are corded electric, so consider your extension cord range before buying either.
