Just the fact that the engine can breathe easily again makes a ton of difference. Plus a little bit of mild tuning and it behaves a lot nicer.On the Massey Ferguson FB page, there are some guys talking about deleting their tractors and having them tuned. Here is a picture after it was done that I found interesting. So far, everyone that has had it done is very happy with the results.

That is interesting. It seems to have gained a lot more horsepower than I would have thought it would. I'd like to see more info on this sort of testing.On the Massey Ferguson FB page, there are some guys talking about deleting their tractors and having them tuned.

And, I wonder if the tractor can hold up to so much added horsepower, or not???
Eddie, I don't think it is any different than some of the JD tractors that share the same engine and frame, I was told by the JD mechanic that my pre-def 2011 JD 5093E could be turned up to get the same HP as the 101E as well as any model in that line that shared the same engine and frame, I have a friend who purchased the same tractor that you purchased and was told by the dealer that when the warranty was up that for about $ 1,500.00 it could be increased to around 100 hp, doing so before the warranty expires would void it.On the Massey Ferguson FB page, there are some guys talking about deleting their tractors and having them tuned.

Those little “HP tuning boxes” are awfully tempting.Just the fact that the engine can breathe easily again makes a ton of difference. Plus a little bit of mild tuning and it behaves a lot nicer.
People turn their tractors up all the time over here and put thousands and thousands of trouble free hours. I feel that tractors have a lot of margin to play with in that regard so it wouldn't concern me too much.Those little “HP tuning boxes” are awfully tempting.
My 7495 Massey is the largest model with the 6.6L Sisu. No issues with power, but the next bigger model got an 8 liter Valmet diesel. I have been tempted to add a boost box to it, especially when I get going uphill with the square baler. lol

I am still amazed at the difference going from my old MF1250 34hp/27pto to my DK4510 45hp/42pto. My 1250 with a 60" brush hog struggled in certain places to where I had to downshift. My DK breezes through the same areas at same or higher ground speed with an 84" cutter without even much of a note change. I mow the same area in less than half time using less than half the fuel.For the Massey Ferguson 4700 Global series tractors, they use the same engine and drive train. Or at least that's what I understand. Mine is the 70 HP 4707 model, and it's the only one without DEF. The other three models, the 4708, 4709, 4710 have DEF. They are 80 HP, 90 HP, and 100 HP. I'm not sure how much you can add to the 100 HP model, but it's becoming more common to bump the 70 HP model up to something close to 100 HP. I'm also told that this is why the 4707 is their most popular tractor. You get a tractor without DEF that is easily to increase the HP to something significant for a small amount of money.
I'm new to having 70 HP in a tractor and I think it has plenty of power. I'm amazed at how much power it has. But I'm only pulling a 12 foot batwing with it. If I was haying, that might make me think about adding more power. Maybe by the time I get my pastures into shape, I'll think about doing my own hay. Massey sells a round baler designed for the 70 HP tractor, so it could go either way.

So does New Holland and even the new Kubota BV series (can be operated with under 70 pto). It all has to do with how the infeed is set up. NH uses a set od convex steel discs that keep the bale from rubbing the side sheets (where the frictional loss is and the power requirements come into play). So does Kubota (Kenverland) BV bailers. In fact they are standard equipment on them. Most round baler fires can be attributed to 2 things. either a locked bearing on one of the rolls or the friction created between the side sheets and the bale as it rotates and grows in the bale chamber. I believe Vermeer and JD also use them.Massey sells a round baler designed for the 70 HP tractor, so it could go either way.
If you even thought about doing something like that an open forum on the Internet is the last place in the world to discuss such activity.Today I took my Ram 3500 to an old friend who has owned a diesel mechanic shop for many years. We started talking about the issues I've had recently with my Kubota L6060. You can see more on that here. Water in fuel causes $10,000 damage to my Kubota Grand L6060
As we were talking he said "You know I can 'delete' that tractor for you. This guy owns a well-known and highly respected shop, and works mainly on large trucks, and lots of them
I'm wondering if anyone else has attempted to "delete" a tractor, and what were the results.
I thought we were talking about a homeowners compact tractor that stays in his own yard. But as usual everyone went off about pickups and commercial on road trucks.What do you think we’ve been talking about?
Neither is our sitting president but like you state, not a discussion to have here. More like a discussion to have on 'Top News Talk. There, you can discuss and dissect it all you want to.Seems like your PM is not exactly comfortable with personal liberty, but that discussion will need to take place elsewhere.
