4707

Did you not throw a code? Did the triangle flash wile it was happening?

when a sensor throws a code the triangle will light up and the code will be at the bottom of screen. But the code goes away so you need to write it down or take a pic. the dealer can pull codes but we have no way to cycle through them.

I never threw a code for anything, I think.

Well, thats not good imo. I dont want a wonkey 3pt. My hay mower conditioner is 3pt. Hopefully like others have said and I’ve experienced somewhat is the wonky will stop with draft off. I couldn't imagine the rage if i need to mow hay and this thing decides to poltergeist.

Diesel emissions
1. diesel engines produce NOX which like cow farts are bad for the environment, to reduce NOX due to high combustion temps so a exhaust gas recirculation (egr) was introduced to ad cooled oxygen depleted gas to the intake to cool the combustion but this created more soot.
2. To reduce soot a diesel particulate filter (dpf) was added which needed to run hot especially during regen, more heat more NOX so the SCR was added to inject urea to convert the NOX into nitrogen and water.
Some manufactures went with a lean fuel system to be able to eliminate the expensive dpf and instead run a diesel oxidation catalyst (DOC) and scr with def.
Massey Ferguson 4707, 4708, 4709 and 4710 all use the 33AWIC engines with different fuel maps in the ECU,
The 4707 is a detuned 4710 without the emissions so I chose to purchase a 4707 and install the 4710 fuel map.
I hope I got this emissions info right.

Same turbo and injectors? That would be a great work around to get a 100hp no def tractor, all though you still have the scr with high pressure fuel, egr and a hotter running diesel engine than non goverment screwed up engines.

It's fairly common for people to buy the 4707 because it doesn't have the DEF stuff and tune it up to 100hp or more after the warrantee is up.

 

[daugen]

someone has/had a kit for that upgrade online, was about 300 bucks to get 30hp.
seemed like quite a bargain since the frame was always sized at the 100hp level anyway

I didn't need the extra hp, wasn't running hay balers or things like that
I am curious to know if the oem 100hp pistons and rings are the same as the 70hp base version.
want to know if any upgraded parts included

I always enjoyed the knowledge I was running a derated engine which was stressing the entire powertrain less than
max output. My 4707 was delivered with the same tires at the 4710, big radials that dwarfed what I had before on Kubotas.
but I think the next year they may have decontented the 4707 and put a smaller Trelleborg radial on it. May have been a supply issue,
larger size was all they had when they built mine. A feeling of unstoppable power and grip out the wazoo.

I bought hay from a guy a few years ago that tuned his 4707 to 100 hp for haying. He said the extra HP made a huge difference, and he liked the tractor a lot more after doing that. I only bought from him once because he was always sold out when I called him again. I don't know any of the details of what he used to do this.

Usually pistons are the same, but injectors and turbos are bigger on the higher HP with the same engine. A quick cross reference of parts will show if its just a tune, but rarely thats the case.

 

[Hersheyfarm]

a quick parts search shows all parts are the same except the turbo, which is can be crucial to get full hp.
Ford for instance detunes their cab/chassis trucks and one thing is a smaller turbo.

thanks Hershey Farm for looking that up.
makes sense to put a bigger blower on it, match more fuel with more air
The early kit didn't have a new turbo, makes sense though.
