From the hitch pin in the drawbar measure 136in this will be the centerline of the tractor. So you want to have the marker set that way when you come back after turning that will be where the center line of the tractor lines up. If you want the guess row wider than 34in move the marker out more.

You have to do your own calculations. 2,4,6 row? WFE or NF? If WFE do you want to center the tractor over the mark or track the wheel? Either way just measure until the guess row is 34 inches from the one on the last pass. Example: Assuming a 4-row planter on a tractor with a WFE, both front and rear wheels set to 68 inches (center of tire to center of tire) so that they run in exactly the center between the rows--with the front wheel in the mark--the wheels running between the 1st and 2nd and 3rd and 4th rows, the marker would make its mark 68 inches from the center of the previous wheel track. With a single front wheel or NF, the mark will be 102 inches from the center of the previous rear wheel track or a full 136 inches from the center of the NF between the two middle rows -- a four row planter covers 136 inches per pass, 6 row 204 inches, 2 row 68 inches, etc. If I have miscalculated, someone will correct me.

Yes Sir,

Bless your heart, I think of you as my neighbor, but you are making this wayyyyy harder than it is. Forget the tractor's wheel tracks and front end. :>)

For a four row planter, just measure out 2 1/2 times the row spacing from that outside opener. Set your marker there and go have a glass of iced tea. :>)

I grew up with NF tractors. Lined the radiator cap up with the mark, done it enough times I don't have to think about it. I have on occasion planted with "modern" tractors with the usual WFE, that someone set to run the front wheel in the mark (probably me)-- make one pass turn around, put the radiator cap on the mark -- you know the rest of the story. Reason I said measure from the wheel track, is that I prefer to measure even row widths. Usually used 30 inch rows, easier for me to remember 30+30=60, than 30+(30/2)=45. I'm a measure twice, cut 3 times person, sometimes worse than that.

OK what is two and one half the row spacing??? This is a 4 row planter set at 34" rows. 34x2.5=85 Is that the length of the arm itself?

Yup, Allen makes it easy. On a four row planter the center of the tractor will be 2.5 rows away from the last row planted. So, yes your calculation is correct unless you sit cockeyed on the tractor like my uncle used to. I had to make one marker 2 inches longer and one marker 2 inches shorter to get even row with (on 38” rows). Whenever I’d check him he was right on but as soon as I’d walk away he moved and sat cockeyed. I finally just moved them when he wasn’t around and everything was good after that.

Lot of people are cockeyed, such as me. People usually don't used markers on implements such as wheat drills provided they aren't too wide, for crops that aren't cultivated. With a little experience you learn where to drive, just like with a tillage implement. With my eyes, though, going one way the guess row is pretty close, the other way it's a several inches off. I can compensate for that, but keep forgetting which is my good and bad eye. Particurly embarresing with a tillage implement where I leave this nice row of weeds every second pass.

I just re-read your post. The measurement is from the last ROW, not the length of the marker. You will need to drop the marker, measure from the last row to the end of the marker and set the distance at 2.5 X row width.

If your not concerned about the tractor tire spacing....measure from the center of the planter (or drawbar on tractor), and set marker at 136" (4x34). Hound

You guys have made all this way too hard! Buy two planters and park the second one behind the first.. you can figure it out from there. LOL Jon
