my landy passed her test today after being off the road for the last 2 years. Still got a prob with the gearbox not coming out of 4 wheel drive but got freewheeling hubs on so not realy worried at the moment, just pleased to be back on the road she is 48 years old now.
for the gearbox its probably the front selector shafts seized on the front output housing near front prop a good wire brushing and wd40/grease should allow it to move
