119 to be lowered to the operative trench cutting position as shown in fig1 the terrain slicing rotor 34 operatively connected to the gearbox 120 is angled down from horizontal gearbox centerline 144 so that when it is at full cutting depth the terrain slicing rotor 34 is positioned with intersection point 105 on or above the top surface of terrain 64 at location 105 as noted above with respect to the first embodiment of the edger 10 if terrain slicing rotor 34 is positioned with the intersection point 105 below the top surface of terrain 64 the rotary cutting forces of the terrain slicing rotor 34 engaging with the terrain start to steer the machine 113 more to the side instead of straight ahead the terrain slicing rotor 34 of the axle pivot drop edger 113 is exactly the same assembly and has substantially the same operative function as the first embodiment of the edger 10 described above in conjunction with fig5 7 except that the trench is not formed with a u201c curved shape u201d slanted wall 72 created when raising the terrain slicing rotor 34 out of the terrain 64 the pivot geometry of the axle pivot drop edger 113 allows for the formation of a straight slanted wall which lessens the amount of soil being cut by the rotor 34 and the power required to do so to operate the.
