The speed control level on my 1450 has been out of adjustment since I bought it in 2020. As the image shows, the tractor's neutral (as far as the pump trying to move the tractor forward or reverse) was when the lever was in the position shown in the picture. I have been reading our website's document "Operation Neutral Adjust for Hydros" and various YouTube videos on how to get the speed lever to be in neutral. I performed this according to the document and I was thrilled when the tractor was in neutral when the lever was in neutral. The problem I now have is, I have almost no power backing up in a flat area. Any incline and the tractor will not move. The fluid is full and fairly fresh with an actual CC hydro filter. Is this an indication that the pump is wore out?
