I bought my first tractor and it is a old yanmar ym 1500, small and need TLC! Hope I can get some knowledge from someone who knows more about the product line! My tractor has a 2tr15 engine and I need to replace due to cracked block. I want to see if anyone knows if a yanmar 2T72 will fit the Yanmar YM1500 since it痴 a different engine model but very similar. Thank you for any help!
