MADISON, Wis. (AP) -- Gov. Jim Doyle has issued an executive order giving farmers another month to transport heavy harvest loads.

State law exempts vehicles carrying crops from road weight limits from September through November. Doyle's order extends those exemptions through the end of December.

The governor says the wet fall has delayed the harvest. State agriculture officials say as of Monday only about 59 percent of the corn crop and 94 percent of soybeans were in. Plus the wet fall has made the crops heavier than usual.

A coalition of groups including the Wisconsin Agri-Service Association, the Wisconsin Corn Growers Association and the Wisconsin Farm Bureau asked for the extension.
