I have read on here somewhere that putting your attachments down from your 3 point is a good idea, especially if you have kids that are around the tractor. Just in case they release the lever and a quarter ton comes down on them.
Lately I have been faithful and lowering it. Every time I go out and snow blow I raise it up. This last time it would not move. I thought it just might be cold but I tried again after I have been using the blower for a while, and it still wouldn't move. Front hydraulics are working great.
What could it be?
