연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A deck lifting and height of cut assembly for a lawn mower, in which the deck lifting assembly includes at least one movable component and the height of cut assembly includes a height adjustment mechanism having a plurality of stop surfaces. A prop extends between the movable component of the deck lifting assembly and a first stop surface of the height adjustment mechanism to prevent the cutting deck assembly from lowering below a first height. The height adjustment mechanism is adjustable to place a second stop surface in engagement with the prop so that the cutting deck assembly is prevented from lowering below a second height different from the first height. The prop may also be used to maintain the cutting deck assembly in the full-up position during travel of the lawn mower between work areas.

1. A lawn mower comprising: a plurality of wheels;a frame supported by the wheels;an operator platform assembly coupled to the frame and configured to support an operator;a control tower extending vertically from the frame in front of the operator platform assembly, the control tower including controls within an operator zone, the operator zone being within reach of the operator of the lawn mower while standing on the operator platform assembly during use of the lawn mower;a mower drive assembly supported by the frame and driving rotation of at least one of the wheels to propel the lawn mower;a cutting deck assembly including a cutting deck and at least one rotatable cutting blade beneath the cutting deck, the rotatable cutting blade rotating under the influence of the mower drive assembly, a height of the cutting deck assembly corresponding to a height of cut at which the cutting blade cuts grass under the cutting deck; anda height of cut assembly including an adjustable height setting member providing a plurality of stop surfaces and a prop engageable with the height setting member, the height of cut assembly also including an adjustment mechanism that actuates the adjustable height setting member to place the prop in abutment with a selected one of a first stop surface and a second stop surface, the adjustment mechanism including a height setting operator interface located in the operator zone of the control tower, anda linkage operably connecting the height setting operator interface and the adjustable height setting member,wherein engagement of the prop with the first stop surface on the adjustable height setting member holds the cutting deck assembly at a first height corresponding to a first height of cut, and engagement of the prop with the second stop surface on the adjustable height setting member holds the cutting deck assembly at a second height corresponding to a second height of cut different from the first height of cut. 2. The lawn mower of claim 1, wherein the mower drive assembly includes first and second motors driving respective first and second of the plurality of wheels; and wherein the first and second motors are independently controllable to permit zero radius turning of the lawn mower. 3. The lawn mower of claim 1, further comprising a cutting deck lift assembly operable to raise the height of the cutting deck assembly; wherein the cutting deck assembly lowers under the influence of gravity upon release of the cutting deck lift assembly; wherein the prop abuts the first stop surface of the adjustable height setting member to prevent the cutting deck assembly from lowering below the first height. 4. The lawn mower of claim 3, wherein the prop includes a first end interconnected to a movable component of the cutting deck lifting assembly, the movable component moving in a first direction during raising of the cutting deck assembly and in a second direction during lowering of the cutting deck assembly; wherein the prop includes a second end movable in response to movement of the moving component into engagement with one of the first and second stop surfaces of the adjustable height setting member; and wherein the prop resists movement of the movable component in the second direction while the prop is engaged with one of the first and second stop surfaces. 5. The lawn mower of claim 4, wherein the movable component includes a pivotable lifting bracket. 6. The lawn mower of claim 3, wherein the adjustable height setting member is adjustable to place the prop in abutment with the second stop surface to prevent the cutting deck assembly from lowering below the second height. 7. The lawn mower of claim 1, further comprising a deck lifting assembly including an actuator in the operator zone, the deck lifting assembly operable to lift the mower deck assembly upon actuation of the actuator, to remove the prop from abutment with the adjustment mechanism; wherein the adjustment mechanism is adjustable while the prop is not in abutment with the adjustment mechanism. 8. The lawn mower of claim 7, wherein the actuator includes a hand actuator that is actuated by an operator's hand and a foot actuator that is actuated with an operator's foot. 9. The lawn mower of claim 1, wherein the adjustable height setting member includes a cam having a cam surface that includes the first and second stop surfaces. 10. The lawn mower of claim 9, wherein the cam surface includes a shoulder associated with each of the first and second stop surfaces; and wherein the prop engages the associated shoulder when engaging the first and second stop surfaces. 11. The lawn mower of claim 1, further comprising at least one prop bracket defining a slot; wherein the prop includes a transverse pin received within the slot; wherein movement of the prop into and out of abutment with the adjustable height setting member is guided by a transverse pin in the prop moving in the slot. 12. The lawn mower of claim 11, wherein the slot includes a height of cut zone and a travel zone; wherein the transverse pin is within the height of cut zone while the prop engages the first and second stop surfaces; wherein the transverse pin is within the travel zone when the cutting deck assembly is moved into a full-up position that is higher than the first and second heights; and wherein the cutting deck assembly is maintained in the full-up position by engagement of the transverse pin in the travel zone to facilitate movement of the lawn mower between areas of vegetation to cut. 13. The lawn mower of claim 1, further comprising a detent mechanism for resiliently holding the adjustable height setting member at a selected position; wherein the detent mechanism permits movement of the adjustable height setting member upon sufficient force applied to the height setting member.
