Walk-behind lawn mower sulky latch assembly
View Patent ↗A walk-behind lawn mower includes at least one of: (a) a latch assembly for receiving a folded-up sulky for storage during transport and the like; (b) inboard mounted control rods extending downwardly from a handle control assembly area of the mower, so that actuator shafts for the hydraulic pumps are located on inboard sides of the pumps so as to oppose one another; (c) a handle control assembly for allowing the mower to be operated in an efficient manner with operator comfort during turns and the like; and/or (d) a pump lock-out system including a lever(s) for actuating both a braking force to be applied to at least one wheel of the mower and a pump lock-out system for causing the pumps to be locked in a neutral position.
1. A walk-behind lawn mower comprising:
an engine for driving at least one cutting blade;
a sulky attached to the mower, wherein the sulky comprises a substantially vertical pivot axis structure which is aligned substantially vertical relative to the ground during normal sulky operation when the sulky trails behind the mower, wherein a foot platform of the sulky pivots relative to a front arm of the sulky about a pivot axis defined by the substantially vertical pivot axis structure;
a latch assembly for coupling a protruding member of the sulky to a spring-biased latch of the latch assembly when the sulky is folded up from a deployed position to a stowed position so that the latch assembly of the mower can hold the folded-up sulky in the stowed position;
wherein the protruding member extends outwardly from a body of the sulky so that at least a distal end of the protruding member defines an angle θ of from about 30 to 70 degrees with the vertical pivot axis of the sulky; and
wherein the protruding member of the sulky is directly coupled to the spring-biased latch when the sulky is folded up in a stowed position, but the protruding member of the sulky is not directly coupled to the spring-biased latch when the sulky is in a deployed position during normal sulky operation when the sulky is trailing behind the mower.
2. The mower of claim 1 , wherein the latch assembly is located under a dashboard of the mower.
3. The mower of claim 1 , further comprising a buttress plate located laterally forward of the latch, so that a leading portion of the sulky is adapted to hit the buttress plate when the sulky is moved into the stowed position with excessive force.
4. The mower of claim 1 , wherein the protruding member of the sulky extends outwardly from the vertical pivot axis of the sulky.
