Abstract
A lawn mower is provided having improved steering controls, namely a "trim" feature which may be adjusted while the mower is in a forward speed setting. Further provided is a park lock feature which locks the speed controls of the mower. Finally, a neutral latch feature is provided which becomes engaged when the left and fight steering controls of the mower are simultaneously position in either a neutral or a reverse position.
Claims11
A lawn mower capable of traveling in a straight forward direction and also turning left and right under the control of an operator, said lawn mower comprising:
- a frame;
- an internal combustion engine mounted to said frame;
- at least one vegetation cutting blade;
- means for rotatably driving said blade by said engine;
- first and second drive wheels rotatably mounted relative to said frame, for propelling said frame relative to the ground from rest to a forward speed;
- first and second drive train means for transferring power from said engine to corresponding first and second drive wheels to cause each of said first and second drive wheels to rotate from rest to a set forward speed;
- first and second speed control means, each independently movable from a neutral position to set forward position, said first and second speed control means independently controlling the amount of forward speed of said first and second drive wheels;
- and
- first and second stop means for setting said set forward positions of said first and second speed control means, to allow said operator to independently limit the amount of speed obtained by said drive wheels, said first and second stop means adjustable relative to each other and together comprising:
- a) a trim control body mounted relative to said frame;
- and
- b) a stop plate mounted relative to said trim control body and defining first and second stop cams each defining corresponding first and second stop surfaces for limiting the forward travel of said first and second speed control means, said stop plate being movable by an operator relative to said trim control body to allow said operator to adjust the positions of said first and second stop surfaces relative to each other, in order to independently adjust the first and second set forward speeds of said first and second drive wheels.
A lawn mower capable of traveling in a straight forward direction and also turning left and fight under the control of an operator, said lawn mower comprising:
- a frame;
- an internal combustion engine mounted to said frame;
- at least one vegetation cutting blade;
- means for rotatably driving said blade by said engine;
- first and second drive wheels rotatably mounted relative to said frame, for propelling said frame relative to the ground from rest to a forward speed;
- first and second drive train means for transferring power from said engine to corresponding first and second drive wheels to cause each of said first and second drive wheels to rotate from rest to a set forward speed;
- first and second speed control means, each independently movable from a neutral position to set forward position, said first and second speed control means independently controlling the amount of forward speed of said first and second drive wheels;
- and
- first and second stop means for independently setting said set forward positions of said first and second speed control means, to allow said operator to independently limit the amount of speed obtained by said drive wheels, said first and second stop means adjustable relative to each other;
- and single point trim control means for adjusting said first and second stop means relative to each other.
