John Deere 4640 Horsepower Discovery 

Lol had a 4630 back in the day turned up so high the turbo would burn off all the paint on the hood and then it would glow cherry red, which was real cool looking plowing or disking at night. Bought it in sikeston at the auction. Won all the local tractor pulls. PowerShot trans, it would pull any implement I had in road gear if you wanted to, well that may be an exaggeration but nearly so. Red bay Alabama. It's probably still going strong somewhere. I wish I still had it.

“Why did my engine shit it’s pants”

Hey sir i gotta 4850 with a nippindinzo pump. (or however the hell u spell it) LOL. I pull a 16 row planter it pulls fine but got some new farm ground with steep ass hills. Would this be the same thing when it comes to turning it up? Also what did you do with that upper screen to help with turning it up? I think id only do 1.5 turns just wanna make sure i do everything right. Is there away to get ahold of you to get the answers to this? Im gonna be pulling a 5 shank ripper tomorrow. Turnin it up would help with that. I just want a little more vinegar in her piss ya know!

The gear box can't handle the extra added power be careful adjusting this governor because transmission are expensive for those size machines I've seen this destroy a good tractor

How much more hp does that give you?

Now, thats not chinese steel in them there discs !

These old boahs are jems

Which way do you turn it? clockwise?

Would turning up a 6030 be the same thing?

Play with fire and you shall be burnt!!!🤣
