Anyone have an opinion on a Ford 7700?

Curious about their reliability.

Ford 7700 has turbo four cylinder engine, need to idle at 1000 rpm to oil turbo properly. Give time to cool down before shutting down the engine. These are a good general purpose tractor. Don't overload it and they are OK. Load monitor can cause trouble in back end and take it easy on dual power shifts on the go. It really depends on what condition the tractor is in and how many hours it has done. Sold mine a few years ago.

like stated below, how its been treated will tell the tale now, I ran one where I worked drilling discing and pulling a 10' mower doing road ditches, cleaning snow, I put over 5000 hours on it with few issues, change the oil in the injection pump every time you change oil I did at 100 hours,, we had a couple people that were hard on clutches and could take it out in a couple hours, I never had a issue but they did it four or five times when ever they ran it, this one was fwa I am a CASE man but I was impressed with the tractor, decent cab a/c worked well, never had a dual power issue,

We've got one with 6500 hrs on it with no problems. Its had a throwout bearing, a set of tires, a few batteries and a paint job and thats it. Dad worked at the dealership when it was sold new and they set it around 95 horse and i think its still got it today. We got it when the guy traded it in on a new 7710. Some of the ford engines do have electrolysis problems and will develop a hole in the cylinder wall would be the worst problem that might happen. We've got 27 tractors and the 7700 is one of my favorite to use.

7700 is a rowcrop. I have a 7600 - the utility version. 8000 hours. It's been split twice - once for a clutch, once for a pto drive hub and input shaft seals. Engine has never needed anything beyond normal maintenance. Using coolant conditioner will help prevent the cylinder wall cavitation. ..if the damage hasn't already been done.
Idle is still at the original setting of around 700 rpm. Never heard of needing to have it higher. Dual Power is made to be shifted under power. Just don't use it to slow down in roadgear.

Mine has been on the place from 666 hours to about 7000 hours now. Typical Ford pto rehab once, inject pump twice, a clutch. Dad used it a little hard, doesn't cool well or pull as hard as it used to, but been a good tractor for being used a bit too hard in its day.

They're about as tough a horse as you'll get for that vintage. Don't turn it up too much, keep clean oil in it (100 hours), dump a bottle of DCA4 coolant conditioner in it every couple of years and blow the rad out a couple times a year... They're run the better part of 100 hp and live a long time.
And don't drop the DP into low to slow it down... it's fine to downshift it under power when it's losing speed but not when it's gaining speed/coasting. I was never a big fan of full power upshifts either so slack off the heat when you make that shift. Otherwise, Dual Power will last a long, long time.
Now if you want to turn it over 100 hp... all bets are off. They will overheat... they will tear clutches apart... and eventually they'll overheat and melt.
