A subsurface weed tool makes use of different detachable blade attachments to cut the roots of weeds. The tool can be used for other purposes such as aeration of the soil. The tool comprises an elongate hollow supporting member having an upper end on which is mounted a motor. An elongate drive shaft or rod is operatively connected to the motor and extends through the supporting member to the latter's lower end. A reciprocating drive unit is mounted on this lower end and includes a drive conversion mechanism connected to the bottom end of the drive shaft and capable of converting rotary motion to a reciprocating linear motion in a certain direction. A blade attachment is connectible to the conversion mechanism and can include a planar blade member with a forward cutting edge. The blade member is reciprocated rapidly in a rear to front direction.
