Agricultural tractors. Test procedures – Rear three-point linkage lifting capacity
| Published By | Publication Date | Number of Pages |
| BSI | 2018 | 14 |
This document specifies test procedures for determining the lifting capacity of rear-mounted three-point linkage systems:
-
the maximum vertical force which can be exerted by the hydraulic lift at the lower hitch points throughout their full range of movement;
-
the maximum vertical force which can be exerted by the hydraulic lift, at a point 610 mm to the rear of the hitch points on a frame attached to the three-point linkage, throughout its full range of movement.
NOTE 1 A static test provides an adequate comparison between tractors. The test results are used only as a means of comparing tractors and not as a way of recommending the size of an implement which can be carried by the tractor.
NOTE 2 This test procedure can be used to determine the lifting capacity of front-mounted three-point hitch systems.
