Be it known'that I, ANTHONY Kunriia, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented new and useful Improvements in Autoplows, of which the following is a specification. j My invention 'relates to improvements in auto plows, and has forts object to provide' an auto plow with improved means of transi A mitting thepower of the motor to the traction wheels hereby less power of the motor is expended in propellin'g the tractoritself, and'incieased power is utilized to dfaw its load.

A further obiect is to provide the tractor with@ improved means of steering and turning, whereby its turning is effected substantially within"y its o Wn length, by its own A. 1,' with the top of the casing removed.'-
