There's a huge difference between a 2520 and 2510. Neither has a 2020 engine in them. The whole tractor is a good bit heavier than any 2020 ever dreamed of. When they came out with the 2510, it filled a void in HP ranges between the 2010 and the 3010. Even the early 3020 and 4020 models had a stronger engine with an older style transmission. They beefed up the trannys and then added a bigger engine in the 2520, which seemed to parallel the intro of the side console 3020 and 4020, which was also heavier and more HP. All three were much more operator friendly with the side console hydraulic controls. When they went to the -30 series and moved the shifters to the console, they made another big leap. The 2520 went through 3 serial splits, if I recall, and the engine got stronger as time went. It's also one of the easiest to replace with a newer series because of the number made and used in construction and other applications. The 3020 and 3010 didn't have that advantage- there just weren't as many made.

But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
