£40,000 worth of agricultural GPS systems were stolen from a farm in in Little Gransden and police are now issuing advice to farmers.
Cambridgeshire Constabulary say that there have also been three similar incidents this month, with agricultural GPS systems stolen in Sawtry, Stilton and Holme.
The force added that other police forces across England are also seeing a rise in these types of thefts.
"To put into perspective how much these systems cost farmers, at the theft in Little Gransden, £40k worth of systems were stolen," said a post on the Policing Huntingdonshire Facebook page.
"Our Rural Crime Action Team (RCAT) are working with the National Vehicle Crime Intelligence Service, other police forces and partners like the National Farmers Union to help combat these types of thefts.
"We need your help! If you see something that doesn't look right, it probably isn't.
"Seen suspicious vehicles or people near a farm or agricultural land? Let us know."
10 top tips from RCAT
1: Remove all receivers, aerials or antenna gloves when not in use and lock them away.
2: Fit security tethers or brackets to stop units being removed
3: Secure machinery in a locked building
4: Install security equipment, alarms, cameras in your barns/sheds
5: Mark all pieces of equipment with a UV pen or engrave your postcode on your kit
6: Consider data tag
7: CCTV and intruder alarms will deter thieves but ensure they are serviced regularly
8: Keep a record of make, model and serial numbers of equipment and take photos
9: Ensure staff follow all of your security measure
10: Report suspicious vehicles or people to police noting descriptions
