The Walk-Behind Tractor - also called a two-wheeled or walking tractor-allows the user to perform a multitude of tasks in small areas without digging or lifting. It accommodates over 20 different attachments and is popular in high tunnel hoop houses, where farm size is small, and/or where the terrain steep and rugged. It can go where four-wheel compact tractors can't. Most makes/models come with: reversible handlebars giving it front or rear PTO, independently engaged PTO, multi-speed forward and reverse, steering brakes, lockable wheel differential, and easy-interchange implement system. Models range from 5.5 to 16 hp, and electric start is standard on many.
