You're right. It just pulled out. Just required excessive force.
The tractor is old. I bought it around 2001 I think. BUT ONLY 19X hours. Yes that's 3 digits, slightly less than 200 hours. I'm new to this forum (any forum). Did the picture go through?
My JD 5105 front end loader suddenly started "stuttering" while being raised. The 3-pt hitch is also doing it. The hydraulic reservoir is full. However, the hydraulic fluid has never been changed. Could that be the cause? Why so sudden? Hydraulic pump???
