Iowa Sen. Charles Grassley says people always ask him how he has time to mow his lawn in Iowa.He posted photos of his lawn mowing invention on Friday on Twitter."Pretty simple invention but very cheap and it works. But u need big lawn to maneuver in," he said.As you can see in the photo, Grassley uses a John Deere riding mower with a special hitch that is connected to an additional two regular mowers.This appears to give him about a 6 foot swath of mowing capacity.What do you think of the gadget?  Add your comments in the box below or on the KCCI Facebook page.
