Hello, I have question about an issue I am having with my tractor. I am round baling hay with my 3450 softcore baler and when I try to open the baler which is retracting the cylinder it is extremely slow. But, when it is time to close the baler it is strong (like normal) closing the baler. So, what could be causing this for me? Here are some of ideas I have been told that could cause the problem. 1st) I have been told there could be air in the system. 2nd) I have been told there could something plugged like line or filter. If the pump is weak wouldn't it be weak extending the cylinder also? It is very strong extending just weak/slow retracting. Any help would be very much appreciated. I have baled about 122 rolls so far since purchased this tractor a little over a month ago. When I first started baling with it the hydraulics worked great and now it has this issue. It malfunctioned one time the first I used it but it was because the second aux lever would vibrate until it engaged. I fixed that by tying it in place. Then no problems until yesterday.
