First Claim
Patent Images
1. A speed control system for an earth working apparatus, comprising:
- a steering structure including first steering handle support structure, second steering handle support structure, and a steering handle;
said first steering handle support structure and said second steering handle support structure being in substantially parallel spaced relation with one another and generally defining a first plane;
said steering handle coupled to said first steering handle support structure and said second steering handle support structure, said steering handle comprising a first handgrip structure and a second handgrip structure, said first and second handgrip structure extending generally in a second plane, said second plane being non-parallel to said first plane, wherein said first handgrip structure and said second handgrip structure converge toward one another at a non-parallel angle with respect to one another;
a speed control lever movably coupled to said steering structure and coupled to a control cable, said speed control lever having a neutral position when substantially no force is applied to said control cable by a user, a full forward position when full forward force is applied to said control cable in a first direction by said user, and a full reverse position when full rearward force is applied to said control cable in a second direction by said user;
wherein said speed control lever is most proximal said steering handle in said full forward position, said speed control lever is most distal said steering handle in said full rearward position, and said speed control lever is in between said full forward position and said full rearward position in said neutral position.

Abstract
A speed control system for an earth working apparatus. The speed control system includes a steering structure and a speed control lever movably coupled to the steering structure. The speed control lever may be operatively coupled to a self propel system of the earth working apparatus. The speed control lever is at rest in a neutral position, is actuable in a first direction for forward movement of the apparatus, and may be actuable in a second direction for rearward movement of the apparatus.

14. An earth working apparatus, comprising:
-
a self propel system, wherein said self propel system provides said apparatus with powered movement over the ground at a forward variable speed and at a reverse variable speed; a steering structure extending rearwardly from said apparatus, said steering structure including a steering handle having a first handgrip structure and a second handgrip structure converging toward one another at an angle of approximately ninety-five to one-hundred-seventy degrees with respect to one another; and a speed control lever movably coupled to said steering structure and operatively coupled to said self propel system; said speed control lever having a neutral position whereby said apparatus is not provided with powered movement, a full forward position whereby said apparatus is provided with powered movement at a full forward speed, and a full reverse position whereby said apparatus is provided with powered movement at a full reverse speed;
wherein said speed control lever is most proximal said steering handle in said full forward position, said speed control lever is most distal said steering handle in said full rearward position, and said speed control lever is in between said full forward position and said full rearward position in said neutral position. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
