Abstract
There is disclosed a manually powered aeration device having a frame and a removable weight tank which is positioned such that the center of gravity of the weight tank and the aerator cylidner are in substantially vertical alignment.
Claims20
A lawn aerator, comprising:
- at least one frame member forming a substantially planar frame;
- at least one bracket member extending downward from, and attached to, said substantially planar frame;
- mounting means for rotatively mounting at least one wheel member on a lower end of said substantially planar frame;
- at least one aerator cylinder having a plurality of aerating pegs extending radially from said cylinder, said cylinder being rotatable about its longitudinal axis and operatively connected to said at least one bracket member;
- at least one substantially horizontal brace member interconnecting said mounting means with said aerator cylinder;
- a hollow drum;
- at least one flange connected to said at least one bracket member, said at least one flange supporting said hollow drum;
- and
- drum mounting means, associated with said substantially planar frame, for removably mounting said hollow drum to said substantially planar frame above said aerator cylinder.

A lawn aerator, comprising:
- at least one frame member forming an open rectilinear frame further comprising a handle and at least one cross brace member;
- at least one bracket member extending downward from, and attached to, said open rectilinear frame;
- mounting means comprising at least one axle for rotatively mounting at least one wheel member on a lower end of said open rectilinear frame;
- an aerator cylinder comprising one or more interconnected cylinder segments having a plurality of aerating pegs extending radially from said one or more interconnected cylinder segments, said aerator cylinder rotatable about its longitudinal axis and operatively connected to said at least one bracket member;
- at least one substantially horizontal brace member interconnecting said mounting means with said aerator cylinder;
- at least one flange connected to said at least one bracket member, wherein said at least one bracket member interconnects said at least one flange with said one or more interconnected cylinder segments;
- and
- a hollow drum, with at least one sealable opening, removably mounted above said aerator cylinder on said at least one flange such that a center of gravity of said hollow drum and of said aerator cylinder are substantially vertically aligned.
5 more elements
A lawn aerator, comprising:
- at least one frame member forming a substantially planar frame;
- at least one bracket member extending forward of, and attached to, said substantially planar frame;
- at least one brace member substantially perpendicular to, and attached to, said substantially planar frame, a forward end of said at least one brace member attached to said at least one bracket member;
- an aerator cylinder having a plurality of aerating pegs extending radially from said cylinder, said cylinder rotatable about its longitudinal axis and operatively connected to a rearward end of said at least one brace member;
- mounting means for relatively mounting at least one wheel member on a lower end of said substantially planar frame;
- and
- a hollow drum removably mounted on said substantially planar frame.
