Hello, I have a Mahindra 6520, 55 hour total, that until last year worked great. I stopped it for the winter and when I went to move it the following spring the clutch wouldn't engage and let me shift. I don't know that much about Mahindra clutch system and was wondering if anyone else has had this problem and what they checked to fix it. It's like a hydraulic clutch where the reservoir went dry. I have a good tension on the clutch pedal but it will not let me shift into F or R. Is the clutch mechanical or hydraulic? Thank you in advance for any advice that could help. The tractor has been setting in the field for another year now and I need to get it fixed!
