Lincolnshire landowners and rural businesses are being warned by the county’s police to take extra security precautions.
The warning follows a spate of thefts across the county of farm vehicles and plant machinery.
Advice includes immobilising and securing all vehicles and equipment when not in use, particularly in the darker mornings and early evening times.
Police say machinery and tools should be identified, and owners should keep a record of serial, chassis and model numbers of machines. They also suggest painting a name on valuable tarpaulins in letters at least a foot high.
