Hey Deejay,Also Correct,But to throw a spanner in the works,NOT all Predictas had a solid front height adjuster,(Although that is one for speculation),just as only the earlier predictas had the oil nips on the Carby side axle housings.
I have 3 model fours currently (2 are automatics)one has the solid a very early one and the other slits Both were purchased from the original owners BUT they are 15,000 mowers apart.Ive let many basic 4s go and they all had slits for the axle housings:)
