5 years ago I bought a 201 cultivator which was set for wide rows.  Each gang has (5) spiders.  For some reason I thought I remember reading somewhere that to get it set down to 30" rows, that was too many spiders per gang. 

Tonight I dug out my manual and started reading to see what it takes to reset the unit and it makes no reference at all to how many spiders should be on a gang for a given row spacing.  All it says is the model 201 was good for 28" to 40" spacing.  The only info I have about spider/gang sizing is the parts manual which lists 3, 4 or 5 spiders per gang.  Looking more at the manual it lists the 101 model for 20"-28" and seems to mostly show it with (3) spiders per gang. 
 
So to reset the unit to 30" rows, if I just slide all the gang tubes over,  will the (5) spider gangs fit in-between the rows?  Keep in mind the 201 has two gang tubes with gangs in-between each row.  Hopefully someone out there has worked with these alot and knows them in and out.

I have a four row three point a-c. It has five small shovels between the rows. Its set for 38 inch rows. It does a great job . The main bar is long enough for 6  30 inch,  I need the parts for two rows. I would just take some of the shovels of till it worrks right. I haven't been able to run across the parts.  I bought a 825 green one, thats a 6 row. It has alot to be desired for. iS'T  ONE FORTH  the  a-c cultivator. If you just play aroundwith it, you'll get her going.

Michael...I have the Lilliston version 6R30 and it has 3 spike units.  The gang tubes, 7 long & 5 short are set for 30 inches.  There is plenty of lateral adjustment on the spike holder to set the row proximity.   Additional spikes would only cause more overlap of the spike gangs between the rows.  I have the AC operators manual for the 101/102 models and on page 19/34 are the charts for the various adjustments. Do you have shields on yours?   What I really wanted is an AC 95.....Dale

Dale, that is an interesting looking unit.  Did AC make it for them? 
 
Like you said with the (5) spider gangs there will be a decent amount of overlap, which I suppose is not a bad thing.  The question is though if they will fit in-between 30" rows.  I know how wide the gang is but I do not know how close they should be set to the rows which would need to be added to the width of the gang when figuring if it will fit.
 
I must have a different manual because I have no charts on page 19 or 34.
 
No, I do not have shields on mine, but to make things even more crowded on the tool bar I have the "row gangs" (page 9 in my manual).  Which means in between a row I have a long tube with a 5-gang, a short tube with a 5-gang and another short tube with the (2) spider "row gang".

I think it was Lilliston who assisted AC.  Some say the units by Lilliston and the tool bar by AC.  I've seen paint peeled where it looks like Lilliston maybe made the entire unit.  8 row seem to have almost the same tool bar on both brands.  I have to take more Pic's of mine and will forward copies to give you a better view.  That may help sort it out.  I am thinking you maybe are starting from a wide row?  That is why you have the 5 spike.......Dale

Bump.
 
Still hoping to chat with a former dealer employee who might remember setting these up.

I had a 201- 6 row - 30". I'm sure it had 4 spiders per unit. I'm also sure the the units were Lilliston. I cultivated thousands of acres of dark red kidney beans with the 201 hooked to a D-17 IV diesel. I think I may still have the operators manual. The hex bearings are the same as the dry fertilizer augers on a JD planter.
