Kubota GR2110 Differential locking Issue

I brought my Kubota GR2110 out from winter storage and cut the grass for the first time of the season. The tractor has 300 hours on it. When making left turns I noticed the left side rear wheel appeared to be acting like a locked differential as it appeared to be spinning to fast and tearing up the turf on those inside turns. I have not looked under the tractor yet but the dealer said there are cables that are supposed to allow the inside turn tire to slip. Could this be a simple cable adjustment? and if so can anyone give me insight on the correct method of adjusting the cable?

Thank You
