The rear tine tiller has a heavy design meaning your tiller works for you instead of tossing you around. The tine drive motor is directly mounted to the tine shaft, resulting in a system so durable the original tiller was rented out for more than 20 years. Counter-rotating tines break up the most difficult soil, clay, or sod. The wheel drive and tine drive work independently of each other to allow your tilling travel speed to be adjusted to the soil conditions.
