Abstract
A stand-on aerator including a chassis, a pair of first wheels coupled to the chassis, wherein the first wheels are operable as drive wheels, a pair of second wheels coupled to the chassis, and an operator platform extending from a rear portion of the chassis. The stand-on aerator also has an aerator assembly coupled to the chassis, wherein the aerator assembly includes a plurality of reciprocating tines capable of extending from and retracting into the aerator assembly.
Claims20
A stand-on aerator comprising:
- a chassis;
- a pair of first wheels coupled to the chassis, wherein the first wheels are operable as drive wheels;
- a pair of second wheels coupled to the chassis;
- an operator platform extending from a rear portion of the chassis;
- and
- an aerator assembly coupled to the chassis, wherein the aerator assembly comprises a plurality of reciprocating tines capable of extending from and retracting into the aerator assembly;
- wherein the plurality of reciprocating tines are configured to be electrically actuated, and are coupled to at least one spring-biasing member and at least one electric motor;
- wherein the at least one spring-biasing member is configured to force the plurality of reciprocating tines to extend from the aerator assembly;
- and
- wherein the at least one electric motor is configured to overcome a force of the at least one spring-biasing member to retract the plurality of reciprocating tines into the aerator assembly.
