Abstract
A novel harvesting machine is usable with a novel method for transformation from an operating position to a transport position. The machine has a set of work wheels and a set of transport wheels which extend on transverse axes. The transport wheels extend substantially parallel to, and on both sides of the longitudinal axis of the body of the machine. When the work wheels are lowered the resulting raising of the body of the machine permits the transport wheels to be lowered. Subsequently, the body can be lowered onto the transport wheels and the work wheels raised. In a subsequent operation the tongue of the machine is pivoted relative to the body into a transport position parallel to the longitudinal axis of the body. An additional connecting element may be provided for supporting the body when in the transport position.
Claims22
A crop harvesting machine displaceable on a ground, said crop harvesting machine comprising:
- (a) a body having working tools and a structure supporting said working tools, said body further having a longitudinal axis and a vertical middle plane extending at least approximately parallel to a working direction;
- (b) two spaced apart first wheels extending when considering said working direction behind said working tools and connected to said structure by means permitting a modification of the vertical position of said first wheels in relation to said body, said first wheels being in contact with said ground during working in order to support said body during working;
- (c) first means for controlling said modification of the vertical position of said first wheels in relation to said body;
- (d) two spaced apart second wheels separate from said first wheels and being in contact with said ground during transport in order to support said body during transport, said second wheels extending at least approximately in the vicinity of said vertical middle plane of said body and being, when considering said working direction, connected to said structure in such a manner that one of said second wheels is connected to a front part of said structure and the other of said second wheels is connected to a rear part of said structure, and in such a manner as to be able to be brought from a rest position off the ground to a transport position where said second wheels are in contact with said ground;
- (e) a tongue connected to said structure by a joint having an upwardly directed axis, whereby said tongue is able to pivot in relation to said body between at least one working position and a transport position, and whereby said longitudinal axis of said body extends crosswise to said working direction during working and at least approximately parallel to a transport direction during transport, said joint extending at least approximately in the vicinity of said vertical middle plane of said body;
- (f) second means for positively moving said tongue between said at least one working position and said transport position;
- and
- (g) means acting between said body and said tongue at a position spaced from said joint for additionally connecting said tongue to said body when said tongue is in said transport position, said additional connecting means preventing swaying of said body during transport.
