Rotary Blades Editorial Review

The Rotary 6438 MTD 20" Mulching Blade has garnered a mixed reception among users, showcasing both its strengths and weaknesses. Many customers praised the blade for its robust cutting performance, particularly in challenging conditions. One user highlighted the blade's ability to cut through various materials, including tough vegetation and even small tree stumps, with minimal wear and tear—contrasting it sharply with a previous more expensive name-brand blade that arrived dull and unbalanced. Installation seems straightforward for most, fitting perfectly on older models like Bolens and various Home Depot options. However, a few users encountered compatibility issues, indicating that the blade does not universally fit all lawnmowers, particularly electric models, which may lead to frustration. Some customers experienced significant damage to their mower's design due to improper fit, detracting from the overall experience. While the blade generally performs well in cutting and mulching, there are noted inConsistencies in its mulching capabilities, with one user reporting it did not mulch at all. Despite these concerns, many users recommend the blade, indicating satisfaction with its performance once correctly installed. In summary, while the Rotary 6438 blade shows high levels of performance and compatibility with certain models, potential buyers should be cautious of compatibility issues and variable mulching performance. ###
