As I continue my quest for the perfect tractor in the Mihindra line up, I started looking closely at the 30 series tractors. I like the look and the simplicity. Looks like the engine is the same but produces more power through the series. Is the engine the same and if so, how is different horsepower achieved. Is it feul delivery or what. If so, why couldn't I get 65 hp out of the 4530 tractor. What are the other differences other than size and power output. Reson I ask is because I have located a 2007 4530 with 150 hours for about $11,000 which looks like a good price. Just think it might be a little small. Still looking at the 5035 but this tractor buying is harder than picking a bride. Ha Ha. Hope the wife does not see this. Really enjoy all the help and this forum.
