Grass grooming brush apparatus

Abstract

A grass grooming brush arrangement 10 , which is coupled with a propelling vehicle via a draw bar 11 , and which comprises: a central mainframe 13 , carrying a set of brushes 14; a pair of wing frames 21 each mounted on an adjacent side of the main frame 13 and carrying its own set of brushes 22; first adjustment means A, B, C connecting each wing frame 21 to the main frame 13 for folding movement between an operative position and a raised transport position of reduced overall width of the apparatus; a supporting wheel set 23 arranged to support the main frame 13; second adjustment means 24, 25, 30 mounting the wheel set 23 on the main frame 13 for movement between a ground engaging transport position of the apparatus, and a raised position allowing the brush sets 14, 22 to carry out brushing operations on the ground; and drive means 27 coupled with the first and second adjustment means and operative to adjust the wheel set 23 at the same time as the wing frames 21 are adjusted.

I claim:  
     
         1 . A grass grooming brush arrangement which can be coupled with a propelling vehicle and which comprises: 
 a central main frame carrying a set of brushes;    a pair of wing fines each mounted on an adjacent side of the main frame and carrying its own set of brushes;    a first adjustment device connecting each wing frame to the main frame for folding movement between an operative position and a raised transport position of reduced overall width of the apparatus;    a supporting wheel set arranged to support the main frame;    a second adjustment device mounting the wheel set on the main frame for movement between a ground engaging transport position of the apparatus, and a raised position allowing the brush sets to carry out brushing operations on the ground; and    a driving device coupled with the first and second adjustment devices and operative to adjust the wheel set at the same time as the wing frames are adjusted.    
     
     
         2 . Apparatus according to  claim 1 , in which the driving device means comprises a single actuator.  
     
     
         3 . Apparatus according to  claim 2 , in which the actuator is coupled with the wheel set via a pivoting cradle mounted pivotally on the main frame, and is coupled with the wing frames via a tensile link.  
     
     
         4 . Apparatus according to  claim 3 , in which the teosile link comprises an arrangement of pulleys mounted on the frame of the apparatus and cables coupled at one end to an actuator rod, and coupled at their opposite end, to connections with the wing frames.  
     
     
         5 . Apparatus according to  claim 1 , in which the main frame has transversely extending and longitudinally spaced support beams and, each provided with mounting brackets, to enable a draw bar to be coupled with one or the other of the beams, depending upon the required pulling direction of the apparatus.
