Well the JD 7810 will have a POWER Quad not a Quad Range. BIG difference. The Power Quad has FOUR power shifts in each range and the ranges are synchronized so you can shift them while moving if you clutch the tractor.
You did not mention the price of the JD 7810. If it is less than $20K more than the JD 7800 by the JD 7810. They just are a smoother tractor. Also the 496 (8.1L) motor is a step up form the 466 in the JD 7800.
The biggest issue on the JD 7800 with a 19 speed PS transmission is they will shift HARD when the oil is cold and I DO MEAN HARD!!!! Had many complaints in the shop when guys traded in JD 4455 with a 15 sp. PS and bought a JD 7800 with a 19 sp. PS the guys hated how they shifted cold. You can help reduce the hard shift by feathering the clutch pedal while it is shifting. That makes the shift controller soften the shift.
When I said hard shifting here is a true story on that. We had a customer that was a BIG fellow. Around 6'8" tall and just a large fellow. So he always drove with the seat slid all the way back. He came in one winter day MADDER than I had ever seen him. HE had just bought a JD 7800 PS maybe a month before. It had less then 20 hours on it. He wanted to move some corn while the ground was frozen. So he had started the tractor and let it run a while. He took off out his lane with the tractor engine running at about 18-1900 RPM. Not full speed but where the engine had some guts. When he shifted from 13th to 14th ( it could have been 14th to 15th I can't remember which one of those shifts was a hard one) it shifted HARD. It threw him back in the seat hard enough he broke the back window with his head. So I do mean it when I say they SHIFT HARD!!!!
Letting them run at a fast idle when it is cold WILL NOT warm the oil up enough to stop them shifting hard. You need to block the radiator off with cardboard to get them to warm up enough to help.
The only big advantage the 19sp PS has over the 16 sp. PQ is the top road speed. The PS will run 23-24 MPH depending on the tire size. The 16 sp. PQ will only go 18-19 MPH. Now the later 20 sp. PQ trans missions would run just as fast as the PS ones.
