Claim 17:
18. A hand tiller comprising;
a) a handle comprising:
i) a length from a tiller-end to a handle-end that is no more than fourteen inches;
ii) a handle axis;
iii) top side;
iv) a bottom side;

where the top side has a raised thumb flange offset a thumb flange distance from the handle-end of the handle; and
v) a symmetric shape of the top and bottom side;

b) an axel configured on the tiller-end of the handle and comprising:
i) a right axel post extending at and offset angle from the axel to an extended end;
ii) a left axel post extending at and offset angle from the axel to an extended end;

wherein the offset angle of the right axel post and left axel post is at least 10 degrees from orthogonal to the handle axis;
c) a right tiller wheel comprising;
i) a hub that extends over the right axel post;
ii) extending radially outward from said hub;

d) a right tiller wheel retainer that couples with the right axel post to retain the right tiller wheel on the right axel post;
e) a left tiller wheel comprising:
i) a hub that extends over the left axel post;
ii) tines extending radially outward from said hub;

f) a left tiller wheel retainer that couples with the left axel post to retain the left tiller wheel on the left axel post;
wherein each tine of the left tiller wheel and right tiller wheel have a tine portion, wherein the tine curves circumferentially proximal the extended end; and
wherein each tine has a width that tapers from the extended end to the connected end;
wherein each of the left tiller wheel and the right tiller wheel have four or more tines;
wherein the handle, and the axel are a one-piece unit;
wherein the tines of each of the left tiller wheel and the right tiller wheel curve circumferentially proximal the extended end; and
wherein each tine has a tip angle of at least 10 degrees.
