Today's tractor is very similar to yesterday's posting. The Lp engine is smaller. The Lp engine has only 360 cubic inches compared to 376 in the diesel engine. The 730 was built in 1958, 1959 and 1960 in the US. However it was built till 1970 in Argentina. Our 730 Lp has the narrow front with the John Deere " Roll-o-matic " knee action. Our 730 came from Michigan on a trade. It was originally sent to Texas as a new tractor. The serial number is #7326760 making it a 1960 model.
