JD 40 cultivator?

a49deere · Tuesday at 4:32 PM

Currently have a JD 40 standard with cultivators. I can only get my rear tire width down to 54" outside to outside. the white planter I have plants 30" rows, this makes for a tight fit. That's the first problem, what I really want to know is what is the best route to go with the type of end on the "C" tines that are currently on cultivators and tool bar? It currently has the pointed tips, but my soil is hard, and they don't seem to do a great job. Would a sweep work better? What size and angle for a 30" row? I was thinking of swapping to a "S" tine but don't think that will work because of the orientation of the 2" tool bar. Do they make a "S" tine that will work on a tool bar that is orientated like a diamond looking at end of bar? Thanks! Learning as we go!!

According to A I. Which cannot possibly be wrong. .

thank you! I have the rear wheels in as far as they will go without rubbing the fenders to much! The previouse owner put on i believe 12.4 tires so this is the best I can do at 54" outside to outside

If you plan to straddle two 30 inch rows wouldn't you want the tires set at 60 inches center to center?

cultivator is only single row

Your 40S is basically the same as my M and they have similar tread width settings. For the M this is 38, 42, 48, and 52 inches center to center in the back and the optional adjustable front axle was the same. A fixed 38" front axle was standard. Back when these tractors were new this worked well since most rows were 38 to 40 inches wide but modern 30" rows present a challenge. I have my wheels set all the way out at 52" and can straddle 2 30" rows good enough for cultivating. Sounds like with your oversize tires you are limited to the 42" setting which would be really wide for a single row.

2" diamond toolbars used to be very common for cultivator and unit planter setups so any kind of clamp or shank should be available for a custom rig.

Is the row width adjustable on the planter?

I ran into your problem when I started cultivating with a Cub in sweet corn that was planted with a two-row planter. As I recall, with the narrow row spacing of the corn, and the Cub in the narrowest setting which I think is 40", I was cultivating the row straddled and the inner edges of the surrounding rows. If the rows weren't perfectly parallel, cultivator blight was more likely to occur with this scenario. This would be better suited to a two-row cultivator setup on a row crop tractor.

The row width on my JD 246 planter is adjustable, but I picked up a planter for the Cub instead which made life easier all the way around, other than spending the money.

Which way are the wheels dished ? Will the fenders move?

If the cultivator is a Deere front mount unit the mounting instructions, row spacing setups and recommended wheel spacing should be in the cultivator operator's manual. Factory tine options would also be shown.

Likewise your planter's manual will have the info to set different row spacings. Are you restricted to certain row spacing by your harvesting equipment?

fenders will not move, wheel dish is in! believe it or not i do understand how a rear wheel dish and rim mount work!

cultivators on the JD40 standard are mid mount and three-point hitch tool bar mounted! The problem is they were (I believe) set up for 36" rows in the olden days!

For me to straddle two rows i would need to be a minimum of 72" center to center and that would be rubbing the both the rows!

Sorry, I had to ask after seeing some of the questions here over the years .

To straddle two 30" rows the nominal center-to-center wheel spacing would be 60". Since the tires on these tractors are relatively narrow you can make do with something a little less, such as the 52" that my M is set up with.

For me to straddle one row the very max that my rear tires can be outside to outside is 60". With my 12.4 or 12.6 tires, (can't remember), I need at least 13", that puts the very max center to center measurement at 47", and that would be tight up against the inside off the two adjacent rows. The very best i can do is 53" outside to outside.

there there those who measure full width from outside tire sidewall to outside tire sidewall. others who correctly measure from tire centerline to tire centerline

15 Inches plus 30 inches plus 15 inches equals 60 inches center to center straddling two thirty inch rows.
