Just some pix I've collected to help answer the question "What the hell do you do/drive"

The Things we tow behing the 7600, 7700, 7800, and 7810 tractors

	Agri-Tech has about a dozen 7k series tractors, comprised of  7600, 7700, 7800, and 7810's. All are the same except for the small differences in HP, and 50% powershif transmissions, and 50% Quads. (These numbers are for the 7x10 series, I am assuming numbers for the 7x00 series are almost identical.
PTO horsepower at 1,000 rpm	115 hp (86 kW)	130 hp (97 kW)	150 hp (112 kW)
PTO torque rise at engine rpm	38% at 1,100 rpm	50% at 1,365 rpm	50% at 1,365 rpm
Rated speed	2,100 rpm	2,100 rpm	2,100 rpm

16-speed PowrQuad™ transmission	Standard	Standard	Standard
19-speed Power Shift	Optional	Optional	Optional

Deluxe 19-speed Power Shift transmission gives you all the right speeds in all the right places. Speeds as slow as 83 feet per minute for creeper work. There are 8 speeds in the field range, from about 3 to 8 mph, while transport speeds go as high as 24 mph. Power Shift is simple to operate. You can move through all forward and reverse gears without clutching.

This is a picture of a Quad's console, the right most trany lever must be clutched when shifted, however the middle (1 throught 4) and forward, park and reverse don't need to be clutched.

8400

    We just lost this tractor, but it was cool. All the controles were mounted on the right armrest, and needed only minimal flicks of the fingers to operate.

4960

    Older tractor than the 8400, but almost the same traction, size and power. However it is a 16 speed powershift, rather than the kewl ARM controls of the 8400. Havent found any pix yet.

8770

    The big toy, over 450 HP 12 cylinder diesel. Has a hood bigger than a fullsized pickup truck.

This pic is acutally a 9k series tractor, but is the same size and style as the 8770, JD doesnt have any pix of the older tractor on their page =-(

20' disk

    We use the 8770 for pulling a 20' wide disk. the 20' is actually comprised of 2 10" disks that are attached together, but can be seprated and used individually. The spacing between

the actual plates that comprise the tilling portion of the disk is greater than that of the 15' disk, giving it much deeper penetration into the ground (and drag).

15' disk

    We used the 8400, and now the 4960 to tow this disk for the first pass of disking, to cover up the sludge. It is 5' skinnier, and gets much less penetration than the 20' disk, so we can tow it with the smaller tractor.
