Take your hose off and go to a John Deere , Case IH or any agriculture implement dealer and they can make you a replacement hose to the same length and diameter in about 15 to 20 minutes, Tractor Supply Company carries their in-house brand of hydraulic hoses in standard lengths and diameters.
EDIT: You probably do not have any length to spare but a new coupling could be crimped on the existing hose about an inch or two below the hose leak.
There is a Tractor Supply near you at 9273 Cafferty Ct, Inver Grove Heights, MN 55076
If you buy a hose from Tractor Supply, you will need a swivel,
