New to the site.
I have an L5740 with the same FEL problem. Everything else works but the FEL will not do down. I have been monitoring for the solution to this problem and I think I have tried all the suggestions. I have disconnected and reconnected the quick disconnect fittings that connect the loader to the tractor. I have tried the PTO lever in up/down and everywhere in between to no avail. Can there be something disconnected at the fel control lever? Is there a quick disconnect at the control lever location? This was a very sudden issue. Working quite well leveling a small dirt pile and suddenly the fel would not go down. the tractor was purchased from the dealer assembled with the FEL and has worked for 4.5 years.
Any new suggestions would be appreciate before I call the dealer for expensive service.
