Thieves stole riding equipment and garden equipment after cutting the lock on a shipping container.
Concrete statues, a diesel strimmer, lawnmower and generator, were also taken from the field in Wood Lane, Gringley on the Hill, near Bawtry, during the break-in.
Police are investigating the incident which happened during the early hours of Friday, August 5.
Five saddles, six bridles, nine horse rugs, four riding hats, and one child’s body protector were among the haul snatched from the container.
Four distinctive head collars, embroidered with the names Vice Versa, George, Billy and Hercules, were also taken.
The generator, petrol lawnmower and petrol strimmer had also been kept inside the container.
Two concrete statues, one of a horse and cart and the other of an Easter basket, had been on display outside the stables from where the theft occurred.
Pc Thomas Bond of Nottinghamshire police, said: “It appears that bolt cutters were used to break the lock on the shipping container and also were used to remove the hinges from an entrance gate to the field.
“A large number of items have been stolen, including two concrete statues, which would have required a vehicle to move them.”
It is believed the stolen property could have been taken across the border from Grinley, which is just inside North Nottinghamshire, and into Lincolnshire.
