I have been considering upgrading my current tractor. I have read of this similar comparison in a couple of threads. I have read many posts where the "E" series are referred to as entry level or basic machines and the "M" series described as much more tractor. In comparing the 5065E and 5065M with about the same features, I come up with approximately a $10,000 difference. The "M" series is about 1300 lbs heavier, has extendable draft links std., rear work light std. and a 5-cylinder engine vs. the 3-cylinder. For the part time farmer, food plot maintenance, basic property up keep and occasional loader work what is it about the "M" series that is $10,000 better? I grew up on standard gear tractors from the 40's and 70's. The current 5105 with SyncReverser is a huge upgrade from what I was used to. I just can't see the justification behind the "M" series for my uses. Is the performance of the "M" series going to be that much better and more particulary $10,000 better? For reference, I am trying to find something that matches or beats the performance of a Ford 4000 with loaded 16.9-30 rear tires. I gave an offer on a JD 5303 last week, but want to make sure I make the right decision the first time.
Since you are looking at 65 models, I assume you have less than 100 ac to maintain. I have 5083E on my 80 ac property, and I can't think of any job that 5083M would do better than 5083E. Why would you need a heavier tractor? Plowing, baling? I believe E series is perfect fit for small farmers.
JD tractors are one of the heaviest anyway. 5063E would pull 3 bottom plows and bale with small round balers without any problems.
I would not spent 10K more on M series. Instead, buy more used implements.
Specs don't matter. As long as you can do your jobs with E series, buy that series. Don't waste your money.
I knew all the specs of my 5083E at one time, now I don't remember any of them, but I know that it works like a Swiss watch.
Just MHO,
Peter
