I can start the engine on my L2350, but when I try to put it in a gear, the gears grind. I have been using the tractor up until two weeks ago and when I tried to drive it I discovered this problem. I called a local Kubota dealer and he instructed me to put it in gear, depress the clutch, and start the engine in gear. He said to get the tractor moving and rev up the engine and then slam on the brakes. This is supposed to break away the pressure plate from the flywheel, I supposed. I did this 7 or 8 times, but it is still stuck. I have quotes from dealers to replace the clutch for $800 to $1,300. What should be a fair price to replace the clutch?
