A DEVICE FOR THE REMOVAL OF PLANT PRODUCE COMPRISING A CUTTING TOOL (4) ATTACHED TO THE SAID DEVICE, THE SAID DEVICE FURTHER CONSISTING OF AT LEAST THREE ELLIPTICAL HOLLOW POLES (1,2,3); THE SAID HOLLOW POLES (1,2,3) HAVING CROSS-SECTIONS WITH DIFFERENT DIAMETERS, BOTTOM POLE (3) WITH THE LARGEST DIAMETER, TOP POLE (1) WITH THE SMALLEST DIAMETER AND MIDDLE POLE (2) WITH A DIAMETER WHICH ENABLES THE MIDDLE POLE (2) TO BE FITTED IN BETWEEN THE TOP AND BOTTOM POLES (1,3); WHEREIN THE RATIO OF THE LENGHT OF THE MAJOR AXIS TO THE LENGHT OF THE MINOR AXIS IS LOWEST IN BOTTOM POLE (3) AND HIGHER IN THE TOP AND MIDDLE POLES (1,2) AND THE RATIO OF THE LENGHT OF THE MAJOR AXIS TO THE LENGHT OF THE MINOR AXIS OF THE CROSS-SECTION OF THE POLES (1,2,3) IS REDUCED MAKING THE CROSS-SECTION OF THE POLES ROUNDER EVEN THOUGH THE CROSS-SECTION OF THE POLES (1,2,3) REMAIN ELLIPTICAL; AT LEAST A WEB (13); THE SAID WEB (13) IS PROVIDED IN AT LEAST ONE OF THE POLES (1,2,3); AT LEAST A LOCKING MEANS (5,6), WHEREIN THE POLES WITH A SMALLER DIAMETER HAVE EXTERNAL SURFACE DIAMETERS MARGINALLY SMALLER THAN THE INTERNAL SURFACE DIAMETER OF THE POLE WITH A LARGER DIAMETER TO ASSEMBLE THE POLES WITH A SMALLER DIAMETER TELESCOPICALLY INTO THE HOLLOW INTERNAL OF THE POLE WITH A LARGER DIAMETER AND THE POLES (1,2,3) ARE FASTENED TOGETHER BY THE LOCKING MEANS (5,6) AND THE WEB (13) REDUCES DEFLECTION OF THE DEVICE.
