Efficient power transmission became a key design consideration for all lawn mowing equipment. Despite facing systemic discrimination, limited access to education and capital, and often receiving inadequate recognition for their contributions, African American inventors made remarkable advances across multiple fields during the late 19th and early 20th centuries.
While this design was more efficient than manual scything, reel mowers had persistent problems.

Global Impact
John Albert Burr's rotary blade lawn mower design revolutionized lawn care, establishing principles that remain fundamental to modern lawn maintenance technology worldwide.
Unlike many inventors who never saw their designs commercialized or soon lost any benefits, he received royalties for his creations. They frequently jammed when grass was wet or when they encountered thicker patches of vegetation. His success demonstrates that innovative capacity is widely distributed in society, and that supporting and recognizing inventors from all backgrounds enriches our technological development and creates better solutions for everyone.
This made lawn mowing accessible to more people, including those who might not have the physical strength to operate less efficient equipment. Today's mulching power mowers may be part of his legacy, returning nutrients to the turf rather than bagging them for compost or disposal.
Why was Burr's lawn mower important for suburban development?
Burr's improved lawn mower was important for suburban development because it made lawn maintenance more practical and accessible for homeowners.
The late 1890s and early 1900s saw explosive growth in suburban communities as streetcar systems and later automobiles enabled people to live farther from city centers. We assist teachers and teacher candidates in achieving their learning goals. It's also a story of practical tinkerers like Burr who saw problems in everyday life and developed better solutions.
The patent came during a period when suburban lawns were becoming more common and proper lawn care was increasingly important for property maintenance. His innovations in blade design, power transmission, and cutting mechanism efficiency established principles that remain fundamental to lawn care technology more than a century after his death. This absence in the historical record reflects broader patterns of whose stories were preserved and whose were overlooked, patterns that historians continue working to address by recovering the contributions of underrepresented innovators.
These new suburban developments featured individual homes with yardsspaces that required regular maintenance. Burr was part of a generation that included inventors like Granville Woods (railway telegraph systems), Lewis Latimer (carbon light bulb filament), and Garrett Morgan (traffic signal and gas mask), among many others. And remember, all contributions are 100% tax deductible.
He moved to Chicago and also worked as a steelworker. His legacy continues in the millions of lawns mowed each year using rotary blade technology that traces its lineage back to his pioneering work.
Another critical innovation in Burr's design was an improved gear system that provided better power transfer from the push handle to the cutting mechanism.
Every time someone uses a rotary lawn mowerwhether a manual push mower, a gasoline-powered walk-behind mower, or a riding mowerthey're benefiting from principles that Burr helped establish. In fact, even today's mulching power lawn mowers are part of his legacy.
