Claims8
A power mower comprising:
- a cutting deck;
- at least one drive wheel;
- an engine for driving at least one cutting blade;
- a deck lift system for selectively raising and lowering the cutting deck, said deck lift system including:
- a deck lift lever which when pulled causes a laterally oriented bar and a support to rotate about a common axis defined by an axis of said bar in order to lift said cutting deck;
- a pivotal latch pivotally coupled to said support at a latch pivot axis;
- a spring for biasing said pivotal latch relative to said support;
- wherein said spring biases said pivotal latch in a first direction when a longitudinal axis of said spring is on a first side of said latch pivot axis, and said spring biases said pivotal latch in a second direction when the longitudinal axis of said spring is on a second different side of said latch pivot axis;
- and
- wherein said longitudinal axis of said spring is switched from the first side of said latch pivot axis to the second different side of said latch pivot axis during raising of said cutting deck as said deck lift lever is pulled.
