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 quick attaching coupler is mounted to a tractor three point hitch, with a first actuator linked to latches on both sides of the hitch. The first actuator may be moved by a seated operator between a first position wherein both latches are unlatched and a second position wherein both latches are latched. A quick PTO coupler is mounted to the quick attaching coupler, and has a sleeve carrying a first end of a tractor PTO shaft. The sleeve pivots independently of the latches between a first PTO disengaged position and a second PTO engaged position. A secon...

The invention claimed is: 1. An apparatus comprising: a quick attaching coupler mounted to a tractor three point hitch, the quick attaching coupler having a frame, a hook on each side of the frame, each hook having a latch pivotable between a first unlatched position and a second latched position; a first actuator linked to both latches by links at least partially enclosed by each side of the frame, the first actuator movable between a first position wherein both latches are unlatched and a second position wherein both latches are latched; a quick PTO coupler mounted to the quick attaching coupler, the quick PTO coupler having a sleeve carrying a first end of a tractor PTO shaft, the sleeve pivotable independently of the latches between a first PTO disengaged position and a second PTO engaged position; a second actuator linked to the sleeve, the second actuator movable between a first position wherein the PTO is disengaged and a second position wherein the PTO is engaged; and a pair of yokes carrying the sleeve, the yokes having an upper end hinged to the quick attaching coupler and a lower end hinged to the sleeve. 2. The apparatus of claim 1 further comprising at least one spring connected to the quick PTO coupler to urge it toward the second PTO engaged position. 3. The apparatus of claim 1 further comprising a toothed coupler connected to the first end of the tractor PTO shaft. 4. The apparatus of claim 1 wherein the first actuator is a handle that pivots between about 10 degrees and about 60 degrees. 5. The apparatus of claim 1 wherein the second actuator is a handle that pivots between about 10 degrees and about 60 degrees. 6. An apparatus comprising: a quick attaching coupler mounted to a tractor three point hitch, the quick attaching coupler having a frame, a hook on each side of the frame, each hook having a latch pivotable between a first unlatched position and a second latched position; a first actuator linked to both latches, the first actuator movable between a first position wherein both latches are unlatched and a second position wherein both latches are latched; a quick PTO coupler mounted to the quick attaching coupler, the quick PTO coupler having a sleeve carrying a first end of a tractor PTO shaft, the sleeve pivotable independently of the latches between a first PTO disengaged position and a second PTO engaged position; a second actuator linked to the sleeve, the second actuator movable between a first position wherein the PTO is disengaged and a second position wherein the PTO is engaged; and a bumper extending from the rear of the quick PTO coupler and having a sloped rearward extending surface. 7. An apparatus comprising: a tractor having an engine, a power take off connected to the engine, and a frame having a cross member and left and right downward extending legs, each leg having a rearward facing and upward opening hook, each hook having a latch, both latches linked to opposing ends of a cross bar having a longitudinal axis parallel to the cross member, the cross bar rotatable between about 10 degrees and about 60 degrees with respect to its longitudinal axis, the cross bar connected to a first actuator to rotate the cross bar and move the latches between a first unlatched position and a second latched position; and a sleeve suspended under the cross member by a yoke hinged to the sleeve and to the cross member, the power take off extending through the sleeve, the sleeve moving forward to move the power take off to a first disengaged position and rearward to move the power take off to a second engaged position, the sleeve linked to a second actuator to move the power take off between the first disengaged position and the second engaged position. 8. The apparatus of claim 7 further comprising a pair of hinged yokes suspending the sleeve under the cross member. 9. The apparatus of claim 8 further comprising a toothed circular plate attached to the power take off. 10. The apparatus of claim 8 wherein the second engaged position may vary between about 3 inches and about 24 inches from the first disengaged position. 11. An apparatus comprising: a tractor having an engine, a power take off connected to the engine, and a frame having a cross member and left and right downward extending legs, each leg having a rearward facing and upward opening hook, each hook having a latch, both latches linked to opposing ends of a cross bar having a longitudinal axis, the cross bar rotatable between about 10 degrees and about 60 degrees with respect to its longitudinal axis, the cross bar connected to a first actuator to rotate the cross bar and move the latches between a first unlatched position and a second latched position; a sleeve suspended under the cross member, the power take off extending through the sleeve, the sleeve moving forward to move the power take off to a first disengaged position and rearward to move the power take off to a second engaged position, the sleeve linked to a second actuator to move the power take off between the first disengaged position and the second engaged position; and a bumper extending over and rearward of the sleeve and having a downward and rearward sloping surface. 12.
