Hi I purchased a L235 that has been sitting up for a while. We got her running but the clutch sometimes doesn’t disengage all the way when the petal is fully pressed. Every now and then it will disengage all the way but it’s not consistent. I was wondering if there is anyway to adjust the clutch or any suggestions to fix the issues without splitting the tractor and changing it out. The only fluid I have not changed out is the hydraulic fluid could that be part of my issue?? Thanks
