I love my 7710, it is a 1986 model year made in Basildon England. My Uncle had a 6610, 7710, and an 8210 all bought from Sid Kuhn back when Bill was running the place.
That 7710 is one tough SOB 👌🏻. That tractor has a lot of “character” lol. I never realized the 7710s were turbo charged. Now it needs a straight pipe so we can hear the turbo and people can stop complaining ab the bent muffler 😂.
It was bought to work not go to parades. 🤣🤣 6610 uses the same motor not turboed and you straddle the transmission. 7610 is the same motor turboed like the 7710 and you straddle the transmission like the 6610. The 7710 platform would have a flat deck without the cab. I've ran it without a muffler and it is way louder but you can't hear any turbo whistle.
The common problem with those blocks was electrolysis corrosion in the water jacket eating through the cylinder wall. I went down that road to with my 7700.
