Steuben County, New York, is looking for some mowing help from an unusual source: sheep and goats.

Public Works Commissioner Vince Spagnoletti is proposing to use animals to chew the grass down at the county’s landfill in Bath. He estimates that the county would save just under $5,000 a year—the amount of money it takes to mow and trim the 32 acres of the landfill. A grant received by the county would allow sections of the landfill to be fenced off for grazing—the only cost involved—making the project free for the county. Spagnoletti is hoping that farmers will be willing to essentially volunteer their animals for service, since they would receive grazing land for free.

For those concerned about danger to the animals, the county has said that there is three feet of clay between the grass and any trash, so the animals should not be at risk from anything toxic.

Spagnoletti said he hopes to begin the program this summer.
