I'm not sure what you mean by "look alike," but as far as the style of turf tires that originally came on the 147, they are NLA. I looked quite a bit because I liked that tread pattern, but never did see anything close.
In the end, I went with some BKT LG's I found on ePay. The tread is very similar to the high-end Carlisle Multi Trac CS. They are in fact even heavier, being 8-ply rear and 6-ply front. BKT's are typically OEM tires for new Kubota tractors.
If your heart gets set on the original look, I suppose you could cruise ebay until a decent used set turns up. I thought about it, but didn't want to outfit a fresh restore with 40+ year old tires. Fresh rubber is good!
