Just to give you an idea of the work she has been on during the last few weeks since the oil change, today has been around 30 degrees C here in Norfolk and I have spent the afternoon "pan busting" in my field.

This is an old Browns sub-soiler.

Been running it at around 20" (500 mm) in second gear, at times it was just like hitting a wall but Henrietta plugged on through the hard patches.

Did cause the coating to lift and crinkle on the exhaust though!
