8050 N7 engine swap

Ok guys, some of you may have read on my other thread about this 8050 I'm working on putting a 685I in it. Got the tractor in the shop today to start working on it. Will be having a rear engine plate made locally. I've gathered some parts and I think I got most of what I need. Tractor will be getting 6 inches added to the side frames, along with widening the hood out around that 5-6 inches. Will tell for sure when I have the engine sitting in the tractor.

Main purpose of this tractor will be running out forage chopper, and really nothing else. Have 3 other 8000s and the 7580 to do tillage work. The 8050 is a powershift tractor also. To remedy some clearance issues, it will be getting 7000 series front sheet metal, but with the 8000 series cab. Dont expect me to post pics everyday though, hopefully it drys out some here and we can get in the fields. But I'll post lots of pics when I do work on it. Thanks guys!

Interesting project

Betting drive train doesn’t make it 3 years. Even just on a chopper.

I say go for it, the best teacher is experience whether it be success or failure. Just think about what our elders thought when pulling tractors hit 200 or 500 hp they said you cant do that to a tractor, now we have field tractors over 500 hp. I know they are designed for that but we had to learn somehow.

No but I know of two that had drivetrain issues.

I’d agree with that AND add that OPERATOR is everything when it comes to sensibility with new levels of power. To that end, Peterson being the mechanic, should have a uniquely better understanding. Go Peterson! I’m looking forward to seeing you get it done. Thanks for sharing.
I’ve seen many stock tractors wrecked by someone who turned up its fuel, weighted it to max, & pulled a size bigger disk/FC or whatever, and bumped it up another gear higher.
Point is - just because it’s got more horses, doesn’t mean you got to use them all, all the time.

7080 was rated at 210-212 HP at the flywheel and 180 HP at the PTO, so looks like close to 30 HP loss.

So should be around the 240-250 hp. Should have a little more grunt than the 426. So possibly not loose as much through the PTO.

Chopper is a New Holland Fp230 with the 29p hay head and just a 824 2 row corn. But we don't do much corn.

You might have to upgrade to a FP240 chopper. Lol

I think the efficacy of the pto drive has something to do with it. Some tractors are just better than others. 5xxx series Deere's for one. Say what you want but everyone I've been around punches way above their weight on pto equipment. My 560D Farmall ran the Ag bagger without even breathing hard.

I'll be starting to tear the 8050 apart today. I'll take a few pics of the tear down.

I want to see how and what is going to hold up the front end of the "BIG 516".

I thought I was the only one that keeps a stump in my shop to hold up the back half of an 8000 series for when they need split. I have used that same stump on three different tractors one twice. Crazy farmers!!!

Could be done pretty easy I would think. I'm going to get a price soon on making the rear engine plates. Depending on price, I may get a couple made.

You ought to.measure them so the rest of us don't have to guess!😎
