I have a Gehl R105 with around 1000 hrs on it. Recently it started making a loud grinding/friction noise on the right side when it first starts to move after releasing the parking break. Once I go a few feet it goes away and doesn't do it again until the break is re-applied. I have changed the chain oil and what I drained out was clear of debris. I also looked in the chain drive for worn parts or debris and didn't see much. I am not sure if I have an issue with the parking break not releasing or if there is possibly a bearing going out somewhere. Has anyone had a similar issue?
