A lawn care device may include a cutting deck housing at least one blade, a rotatable shaft, and a blade coupler operably coupled to the rotatable shaft. The blade coupler may define a blade channel configured to at least partially enclose four sides of a blade inserted therein. The blade coupler may include a support base and a sleeve that is movable relative to the support base based on a compression state of a biasing element. The blade may be insertable into the blade channel by orienting the blade to apply a force to sidewalls of the sleeve to shift the biasing element to a compressed state and rotating the blade proximate to the support base to enable the biasing element to shift to an extended state in which sidewalls of the sleeve define sidewalls of the blade channel.
