Montana and Farmtrac share only some similar models. But if you check out the Farmtracs you will see they have a wider product selection and you will find that not all of them are made by LG Cable. All of the Montana's are made by LG Cable.
As for TYM, some of the models they produce include Kubota engines.
As for the Montana's I looked at a 27hp unit and was totally unimpressed. It was very crude in comparision to the Big 3 and several other brands. I did not drive it, I saw no reason to test something that I would never even consider buying. I later found out that the model I looked at was the bottom of the product line, and did not include many features like rubber floor mats to prevent rusting of the operator's platform and dozens of other details that I've come to expect. Now in fairness, I also understand that some of the other models have the features that I would require on a tractor.
As for the "Big Dung" comment, that one, if you didn't see it on TBN was posted by one of the Kiotidiots by the name of Albumn10. And yes, I did take the opportunity to point out what he posted, even if it was just an honest typo. The guy is one of the worst of the 'pack' and exhibits his ignorance too often for his own good. So the credit for Big Dung actually belongs to a rabid pack member!!!
