Definitions

• the present invention relates to a device which is arranged to be used either for the removal of snow or for mowing lawns and which furthermore can be adapted to carry out additional functions.
• a combined device for snow removal and lawn mow ⁇ ing is disclosed in U.S. patent 4,064,679.
• the device is based upon the idea of using separate rotors, one for snow removal and one for grass mowing as well as another one for raking up grass.
• the rotors have to be ex ⁇ changed to adapt the device for different types of work, so that this is actually not a combination tool in a strict sense of the word.
• the present invention relates to a device by means of which several functions can be achieved without necessitating exchange of tools or rotors or performance of one or more complex working steps.
• a main feature of the invention consists in the fact that the driving motor of the tool is connected to at least one cutter blade along the shovel member.
• the cutter blade cooperates with a shear blade arranged rotatably on the rotor shaft to cooperate with a hinged flap so that when the flap is swung up the cutter blade is in a position not to interfere with snow removal and when the flap is swung down the cutter blade is positioned close to the lower portion of the rotor to cooperate actively in lawn mowing.
• Figure 1 shows the combined snow removing and lawn mowing tool arranged for snow removal.
• Figure 2 shows the tool being used for snow removal.
• Figure 3 shows the combined snow removing and lawn mowing tool in a position for closing the flap.
• Figure 4 shows the combined snow removing and lawn mowing tool in a position for lawn mowing.
• Figure 5 shows the combined snow removing and lawn mowing tool being used for lawn mowing.
• Figure 6 shows the combined tool equipped with two aligned rotors to be driven by a crankshaft.
• Figure 7 shows the combined tool having two inclined conical rotors.
• FIG. 1 shows the combined snow removing and lawn mowing etc. tool set for snow removal.
• the tool in ⁇ cludes a hood 1, a handle 2, a snow or grass ejecting means 3, a motor 4 connected to drive a shovel member 5 provided with at least one cutter blade 6 adapted to cooperate with a flap 7 and wheels 8 provided with level controlling means.
• a shear blade 10 is rotatably arranged on the rotor shaft 5 of the shovel member 5. This is achieved by providing the flap with support mem- bers 11 arranged alongside the rotor shaft 5 * adjacent the arms
• Figure 2 shows the combined tool used for remov ⁇ ing snow. Due to the cutter blade 6 being provided adja ⁇ cent to the shovel member, the snow removing work will even be improved.
• FIG. 3 shows the combined tool in the flap
• Figure 4 shows the combined snow removing and lawn mowing tool as arranged for lawn mowing.
• the flap 7 and accordingly the cooperating shear blade 10 is swung down.
• the rotation of the shovel member 5 results in rotation of the cutter blade 6 arranged on the shovel member 5.
• the shovel member is provided with at least one cutter blade 6 cooperating with the shear 30 blade 10 in the lower position so that cutting of the grass can be achieved.
• the cutter blade 6 cuts the grass supported by the shear blade 10. Since the shear blade 10 is arranged on the flap, which is swung down and locked, the shear blade 10 35 is maintained affixed to the lower portion of the frame, whereby cutting of the grass can take place.
• the combined tool can be provided with a grass collector 13.
• Figure 5 shows the combined snow removing and lawn mowing tool used for lawn mowing. It is apparent that this operation is carried out with the flap 7 in a closing position.
• FIG. 6 illustrates a combined tool having two rotors arranged beside each other.
• each rotor has a cutter blade 6 which covers the rotor.
• this drive shaft must be pro ⁇ vided with a crank-like portion 14.
• Figure 7 illustrates a combined tool having two rotors arranged beside each other.
• these rotors are inclined conical rotors 16 connected by means of bevel gear 17 to a drive shaft 18.
• bevel gear 17 to a drive shaft 18.
• the snow removing performance of the combined tool will be good, as the shovel member is designed just for snow removal. This function is improved inasmuch as the shovel member includes at least one additional cutter blade.
• the grass cutting characteristics will be good, since cutter blades adapted to function well for this purpose are arranged on the shovel member and adapted to cooperate with a cutter member disposed in the lower portion of the frame.
• the ' cutting of the grass will occur in an efficient manner, since the grass is cut and thrown out by the shovel member. Removal of leaves can be achieved when the flap
