S 67;Had problem with error code indicating low fuel rail pressure and engine was losing horsepower. Changed fuel filters and problem cleared up until the next evening. Called agco and then Phil Ryan. Phil Ryan said they had one where the plastic shavings from the fuel tank manufacturing process were blocking the screen inside the fuel tank when the tank gets low. Agco mecjanic said to check the strainer in the fuel line on left side of machine after the fuel shutoff petcock. The strainer was full of plastic shavings from the tank manufacturing process. There is no problem when the fuel tank is full as the plastic shavings float to the top of the fuel tank. It occurs when the tank is low; sooo I guess we are gonna drain the tank and clean the tank filter after spending 100 bucks changing filters.

Our R72 had issues plugging the screen inside the tank. Not plastic shavings but gunk from previous owner. It's a poor design really having the screen inside the tank with no way to clean it short of draining the tank. We did that and we removed the screen and threw it away. Put a 3/4'' plastic strainer from Tractor supply in the fuel line under the cab and a ball valve right at the tank. Now we can shut the tank valve off and the one Gleaner put in the line along the frame and clean the strainer with out draining the tank.

We had that problem three weeks ago on our S67. Had about 150 engine hours on it. We cleaned that inline filter and the dealer took out the elbow where the fuel line is connected to the tank. The shavings slowly filtered down in to it and matted in it. Since no problems, about 40 hours since. We actually started to lose power to where combine would almost shut off.

Also!!!! We lost two paddles on the clean grain elevator. Turns out we lost about a dozen more bolts and countless loose ones that hold the paddle on. So it's worth checking on.

We had the same problem with our 3 9770 swathers, all of them had a problem within the first 20 hours of operation, 2 of them haven't had a problem since bat 50 hours, on of them is going to get the tank replaced this winter, didn't have any problems for about 700 hours then it starts sucking plastic shavings again.
