I'm considering updating my sprayer tractor. Currently I'm running a John Deere 4555 pulling a Top Air 1200 gallon sprayer. I'd really like to go with a John Deere 7930 with an IVT. Is there anything I need to look out for that are common problems? I like the 7930 because it is lighter weight than an 8030 series Deere. It is also still small enough to run a baler if needed. I am wanting more horsepower because when it is soft the 4555 works to pull a full sprayer and some day I might get a bigger sprayer. Is anybody else using a 7930 spraying and if so how do you like it? Also, any recommendations on front tire sizes for ride quality and flotation? Currently have 420R28 on the front of the 4555 and if hardly ever breaks through soft ground. We have a 7730 with a power quad already for baling and feeding and I've gotten spoiled by the size of the cab and how quiet it is. Any advice and suggestions are appreciated.

I pulled a summers 1500 gallon 90ft with a 7930 with IVT for a season, it handled it really well, still had plenty of power while running 520/85/46 and 480/70/34 tire setup on it. Also pulled a 2190 Hesston baler for a season, it had plenty to run the baler but it needed a bit more wheelbase. My 8130 that I curently use, IVT same tire setup, is a gutless pig, pretty much same HP and 7,000 pounds heavier. You should be fine with a 7930.

Freeman, were you running duals on your 7930? What I've looked online most have 380/34 or 420/30 on the front and 480/46 on the rear. We raise mostly wheat and some oats, and spraying with duals you can't usually see the tracks after a couple weeks.
I've considered an 8130 but was concerned about the extra weight and it being a little big to use on a round baler and for possible loader work. If I went with an 8030 series I figured I'd want to go with an 8230 or 8330 for extra power since they are the same base weight as an 8130.

I never ran duals when I sprayed spread fertilizer with it, after I sprayed wheat with it running the 480 fronts and 520 rears you could hardly see where I drove, maybe an inch in crop height difference 3-4 weeks after spraying, you should be fine using a 7930

We ran a 7930 for several years on a sb4000 Brandt 100' 1600 gal sprayer and it works pretty slick. The ivt keeps the speed the same and it revs the engine up when it needs the power and down when it dosent. We have the 710 rears and the big single fronts cont remember the number. At times you need all the traction you can get.
The only issue I have is now we went to a sp sprayer I really wish the 7930 was a 8000 series so we could pull the harrows with it. It's a really fancy loader/auger tractor for us right now.

I think the 7930 fits best for us to be more versatile. It would be big enough to pull our 23 foot disk on occasion, and a 30 foot harrow on hay ground. It would also work as a second baling tractor when I wasn't spraying.

Pretty much top of the line cattle farming tractor. Does every thing really well. Two bales on the loader and the suspension still rides smooth.
