Police have released video footage of two men making-off with a $28,000 bobcat in Carrum Downs.
The CCTV footage shows two men struggling to load the bobcat onto the back of a truck.
It takes the men three attempts to load the bobcat, with the truck finally driving away with the machine perched precariously on the rear of the vehicle.
The incident occurred at a Carrum Downs address on May 15.
The bobcat, a Clarke 873 model valued at $28,000, has not yet been recovered.
It is one of a series of similar thefts that have occurred in the south-eastern and eastern suburbs between May and June.
Police have not ruled out the possibility the thefts are linked.
The stolen equipment consists of trucks, excavators and earth moving equipment worth approximately $1 million.
