Using a pond scoop to make a small levy, so loads can be heavy. 3 pt will raise with heavy load but slowly some times. My issue is after I have dumped a loaded & getting ready to lower scoop to pick up another it will not lower. The CONTROL LEVER GETS VERY HARD TO MOVE & WILL NOT GO DOWN. Even if I force it down half way a empty bucket will not move down. I can occasionally move lever up & down a little at the top of quadrant and get it to work. If it ever does work control lever now moves freely up and down like normal. Fill up scoop, lifts ok drive to dump & dump it. Then sticks up high again in most cases but not all. I am wondering since pan flips to dump the load is this causing some type on Binding of 3 pt. Last time I used it and dumped it stuck up high. I can jump up & down on either lift arm and this does not help. Jump up & down on scoop bucket & shake it. This does not help. So the last time I drove it 200 yds back to shed. When got there I lowered Control Lever the pond scoop lowered as usual. Go figure
