Problems solved by technology

For example, rearward swinging of the front part about the transverse axis of the wheel causes the small rod to move towards the upper part of the elongated hole, so that the tip of the fork is raised relative to the ground, causing the plants to remain on the ground instead of being raked

Embodiment Construction

[0012] Such as figure 1 , 2 and 3, the machine (1) according to the invention is a lawnmower of the tumbling type. The machine (1) comprises a frame (2). The frame (2) comprises a front part (3). The front part is intended to be hitched to a tractor (4) that can move the machine (1) in the forward direction A. In the following description, the concepts "front", "rear", "left", and "right" are all defined relative to the forward direction (A), while the concepts "up" and "down" are defined relative to the ground. The front part (3) in particular comprises a tiller (5) whose length is substantially parallel to the direction of advance (A). The front part (3) is also provided with a ground support member (6) that can rotate relative to the front part (3) around a transverse axis (7). According to the embodiment in the figures, the ground support member (6) comprises at least one wheel (8) rotatable around said transverse axis (7). For example, the ground support member (6) ...

Abstract

The present invention relates to a tedder comprising several tedding rotors (9) with wheels (11) resting on the ground and with tines (12) the tips (13) of which are situated at a height (H) off the ground, a front part (3) of the frame (2) being provided with a support (6) on the ground which is situated forward of the rotors (9) and able to rotate about a transverse axis (7), a rear part (15) of the frame (2) bearing the rotors (9) being articulated to the front part (3) via an elongate orifice (23) in which a horizontal and transverse bar (24) is guided, and via an adjusting member (26) articulated to the front and rear parts (3 and 15) and offset vertically relative to the bar (24). According to the invention, in projection onto a vertical plane (P) parallel to the direction of forward travel (A), the orifice has an inclination (Alpha) relative to the vertical which is such that during work, the height (H) of the tips (13) in front of the wheels (11), relative to the ground, remains substantially constant irrespective of a pivoted position of the front part (3) with respect to the support means (6) about the transverse axis (7).

Description

technical field [0001] The present invention relates to a lawnmower, in particular a tedder, comprising a frame carrying a plurality of tumbler rotors which can be driven to rotate about a substantially vertical or inclined axis of rotation which also carries Small wheels that can be supported on the ground in the working position of the machine, the tumbling rotor has forks facing the ground, the tips of the forks of the tumbling rotor are located at a certain height relative to the ground in the working position, the frame includes on the one hand for The front part attached to the tractor, the front part has a ground support part that can rotate about a transverse axis relative to the front part, in the working position, the ground support part is located in front of the tumbling rotor, and the frame on the other hand includes the rear part carrying the tumbling rotor part, the rear part is hinged on the front part by means of a hinge which extends between the small wheel a...
