Saskatchewan farmers are asking snowmobilers to stay out of fields with unharvested crops.

APAS president Todd Lewis says his office has received some complaints of snowmobiles being driven on unharvested cropland.

He says snowmobiles can cause serious damage to standing or swathed crops.

He says swaths can be scattered and standing crops shelled out by snowmachhines moving through an unharvested field.

Lewis is appealing to all snowmobilers to stay away from unharvested crops.

An estimated 2-million acres of crop remain to be harvested in the Saskatcewan grainbelt.
