The aim of the invention is the construction of a cart suitable for rough roads and fields. According to the present invention, the motorized cart has four wheels which are driven simultaneously. Other than revolving, the front wheels 1 have the facility to turn. All the wheels have a pin 16 for engagement - disengagement from the transmission system. The front wheels have a point coupling system 15. The cart has arm-type steering 4 on which there are control levers 7, 8, 9, 10. The advantages of the present invention are that: the cart is of low cost, light, small and flexible. It provides great safety since the user can manage it with ease, walking behind or in front of it. It has great stability since the centre of gravity of the load placed on the cart is close to the centre of gravity of the cart. It does not get stuck in the soil due to the method of transmission of motion to the wheels. It turns easily due to the arm- type steering and the disengagement of a wheel when turning. It can easily become a trailer since the four wheels have a system for disengaging them. |
