how narrow can 7000 series be set for row crops

Does anyone know a definitive minimum width in inches for 7000, 7010, 7020, 7030, 7040, 7045?
we are looking at needing a sprayer tractor that will go down corn rows and a little room to spare would be nice. It seems like a 7000 with power shift wheels should be a little narrower than say the 7030 and up. Tires would be 18.4.

I have a 7060 set up to pull a planter on 30 inch rows. My suggestion is that you use 16.9 rear tires for spraying. Or 15.5'S if can find a pair.

That may be another way to approach it. Has anyone run through 30" rows with any of the 7000 series with 18.4 tires? I'm thinking they fit but one inch on either side might get old and do more damage potentially.

I ran my 7020 down 30in rows.  If i wanted extra room; the guys i see who went to 42in rubber, seem to have bunches of room.   my front axle was more of a problem then the rear.  the rear i could easily get into the center of the row.  the fronts ran on the outside of the center.  they worked OK but thought i'd clue u in on my journey!

Thanks, if 7020 fits anything less should work too...

7080 and early 8070 I believe

Don,t have measurements but ran a 7030 for years on 30 inch rows with 18-4 by 38 tires.

Guess I should clarify my previous post. "Row cropped for years" in 30" rows with my 7080. The caveat is you must have 18.4X38 tires on power shift rims and have them adjusted all the way to the outside which provides maximum offset. Then slide the assembly on the axle to position it as close to the cab sidewalls as possible. The cab sidewalls on the 7000 series are the limiting factor no matter what model. HTH,Mike

I had a tire customer who purchased a pair of 15.5X38's and tubes new. Every spring after heavy field work was done he would have me come out and take the 18.4's off and mount the 15.5's on the tractor. He then used it for the light farm work, cultivating 30" rows, hay making, etc. When the crops were out, I remounted the 18.4's for fall/spring work. On a 7020. These were Goodyear bias 6 ply tires because at the time the Goodyear 15.5X38's were taller than any other brand.

I have a 7010 that has done a lot of row cultivating and spraying in 30 inch rows with 18.4x38's. Had a 7040 that had 18.4x38 that did same jobs.
