Hello everyone, I was using my 2240 with a 6ft blade on the back to level out some gravel and I lifted the blade up and when I went to put it back down it wouldn't go down. I went out to see if it would work today and when I started it up the blade went all the way up and down about 4 times then when I moved the blade up it wouldnt go down again. However when I shut the tractor off I can put the blade down. Any help would be greatly appreciated.
