NEENAH, Wis. -

After a man was hit and critically injured by a city leaf collection unit earlier this month, authorities deemed the front-loading leaf removal vehicles dangerous.                                      

The Wisconsin State Patrol has forced the city of Neenah to find another method of collecting leaves. The patrol said Neenah's seven leaf collection trucks violate state law. Sgt. Tim McGrath said the front-mounted leaf collectors poses vision problems for operators.

Earlier this month, 43-year-old Daniel Robinson was struck and critically injured by a leaf removal truck in Neenah. He remains hospitalized.

Public works officials said the collection units could be moved to the back of the trucks, but it isn't a quick fix. The change would also turn what had been a one-person operation to a two-person job.

WLUK-TV reports that for now, the city is raking the leaves off the curbs and using front-end loaders to deposit them in dump trucks.
