Anyone ever "delete" the dpf on a tractor?

[EddieWalker]

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.

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.

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.

And, I wonder if the tractor can hold up to so much added horsepower, or not???

Its a good question to address. The manufacturers are notorious for designing equipment barely up to standards to save money. However, tractor drivelines are usually overbuilt to withstand shock loads. I know I have withstood many unexpected shock loads on mine and so far, no damage. Pulling a plow is tough on a tractor. I have hit many an unexpected yank on the driveline this way.
I would think adding some power by deleting is relatively safe.

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.

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

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.

The first thing they typically do, is to remove those speed limit things that tractors have built in. Like on a Kubota M7060 that on 6th gear, high range, it limits the RPM of the engine to 1600RPM or some thing along those lines. They trick the sensor (I believe) and the thing just flies down the road nice and happy.

We always 'turned up' our big over the road diesels by changing the fuel button (on a Cummins engine or shimming the rack on a Caterpillar. Real common place prior to the ECM-T4 crap of today. We all drove by the pyrometer anyway and 1500 degrees was the max exhaust temp before bad things started happening to aluminum alloy pistons, rings and liners.

855 Cummins could be turned from stock output to almost 1000 horses before bad thins happened. Same with 3406 and 1693 Cats. 1000-1500 horse was not uncommon.

Last Cummins 855 intercooled Big cam I had in a Western Star, it was putting 700 to the rear wheels in 13 direct with no issue, so long as I kept an eye on the pyrometer and didn't lug the engine. When you lug a diesel, exhaust temps go up quickly and then the motor suffers.

Still own a mechanically injected (no emissions junk) Caterpillar 3406 E engine in a International Eagle conventional that makes 550 ponies at the rear drives and is as reliable as a rock.

Longevity is entirely dependent on how they are operated and if the operator is a dummy or not.

Myself, I don't feel the need to 'turn up' either of my Kubota tractors, what they make at the pto is quite sufficient for my requirements but being pre 4 mechanically injected (Bosh style fuel rail pumps), they can easily be turned up (injecting more fuel per stroke than stock).

One thing to always keep in mind and that is. the more fuel you inject into the cylinder per revolution, the more fuel you will consume so more fuel used equals added expense and with diesel fuel costing what it does today, if you use a large quantity (like I do), fuel cost per acre run becomes an overhead issue.

Why I won't turn them up. They are easy to turn up but I won't because at rated power, both are very economical to operate and the cost of fuel impacts my bottom line adversely.

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.
