Ok great thanks for the information.The 24 had a different structure to the 27 / 29 - belt drives were different - but its a simple machine - plenty of parts in Denmark as they were sold in larger numbers there - its like any aged machine - bearings and belts can be checked as well as the transmission - engine is probably a Perkins 106 hp - air con and hydro transmission were standard so this should be checked for operation - all gears etc - if you are not expecting a lot and price is inexpensive why not - they dont have a wobble box its a rod on a crank - has a secondary cleaner so very good samples generally - check that the cylinder variator works - just my 10 pennyworth
