Hello Greenman,

Thxs for responding. Good tool that could be easily improved by simply adding a fulcrum point. After sticking into ground: swing out steel arms with metal pads on the end to act as a fulcrum point--then the leverage required is reduced by the teeter-totter action. Save your back and arms!

Ah, you are missing the point. The crossbar is the fulcrum.

You step on the crossbar to drive the tines into the ground, then grab the handles and lean back. The crossbar on the surface of the soil is the fulcrum, and you just swing your weight back. Works very well.

Yeah, they're fun to use. Just make *sure* when using your broadfork in rocky soil, that you don't lean back into a *big* rock. The tines are quite solid, but you have tremendous leverage with a broadfork, and straightening those tines after you bend one on a big rock is not fun.
