IS0 11001-4:1994(E) Foreword IS0 (the Inter
3、national Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has
4、been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical st
5、andardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 11001-4 was prepared by Technic
6、al Committee lSO/TC 23, Tractors and machinery for agriculture and forestry, Subcom- mittee SC 4, Tractors. IS0 11001 consists of the following parts, under the general title Agricul- tural wheeled tractors and implements - Three-point hitch couplers: - Part 7: U-frame coupler - Part 2: A-frame coup

10、 the attachment of three-point hitch imple- ments to the rear of agricultural wheeled tractors equipped with a three-point free link hitch according to IS0 730-I and a bar coupler. NOTE 1 In general, the dimensions associated with the tractor and the implement for use with hitch couplers are the sam
11、e as for the three-point linkage specified in IS0 730-I Due to the special construction and function of the bar coupler it infringes on the clearance zone specified in IS0 2332 The three-point hitch coupler systems constitute a special way of implement mounting. The hitch coup- lers are an additiona
12、l component located between the three-point linkage and the implement making it possible to hitch and unhitch from the operator s seat This part of IS0 11001 applies to categories 2 and 3 of agricultural wheeled tractors as defined in IS0 730-I. 2 Normative references The following standards contain
13、 provisions which, through reference in this text, constitute provisions of this part of IS0 11001. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of IS0 11001 are encouraged to investi- gate the poss
14、ibility of applying the most recent editions of the standards indicated below. Members of IEC and IS0 maintain registers of currently valid International Standards.

15、ricultural tractors and machinery - Connection of implements via three-point linkage - Clearance zone around implement. 3 Principle of bar coupler A bar coupler system is a two-phase implement coupler where the three-point linkage of the tractor is fitted with a crossbar between the lower hitch poin
16、ts, and the implement has the provision to be picked up by the bar (see figure I). 4 Dimensions Dimensions shall comply with figures 2 and 3, and table 1. For the three-point linkage clearances, see IS0 2332. 5 Locking device A locking device with a positive latch shall be provided to prevent uninte
