After hurricane Matthew my Ford was surrounded by water. The water level did not get above the running boards on the side of the tractor. When the water receded I found that the clutch was not disengaging enough to allow me to put the tractor in gear. I let the tractor run for about ten minutes and I was then able to change gears and engage the PTO. I recently tried to use the tractor again and was not able to get the tractor in gear at all. The clutch will not disengage at all. I adjusted the clutch pedal and there was no difference. Before I start a replacement are there any drain plugs for the clutch housing? Is there anything I can look for to see if there was any water damage to the clutch?
