All three models use a steel 20 inch cutting deck that can be raised or lowered to 7 different positions from 1 to 4 inches high. The self-propulsion system works without needing regular maintenance, and uses a variable speed rear-wheel drive transmission. The front wheels are 8 inches in diameter to move smoothly over uneven surfaces and avoid damaging the lawn.
