John Deere 750 No-Till Drill

Good day,

I posted this in the JD section but thought I'd post it here as well hoping for some feedback.

I'm planning on starting my hunt for a 750 drill pretty soon. 

As previously mentioned, I'd like to use it for banding dry fertilizer into our existing haystands. To be perfectly honest, I have to profess my ignorance of fertilizer application never having done it before. 

I'm aware of the corrosiveness of the fertilizer and the need to clean / wash the boxes out thoroughly afterwards but I'm more curious about the actual application and the capacities/limitations on the machine itself. 

I see that some drills are equipped with a dedicated fertilizer box but I assume that one could simply use the main seed box as well or in addition to if desired? What would the range of fertlizer application rate be using one of these machines? 


Regarding the seeding aspect on the machines with the dedicated fertilizer box, where is the fertilizer actually placed with respect the seed? How effective is the seed VS fertilizer placement? We plan on sowing alfalfa, grass mixes, triticale, rye, oats, etc. Just wondering if a machine not having a fertilizer box is a deal breaker? I know its inefficient but making a pass to fertilize & another pass to seed(or vice versa?)would not be the end of the world for us if needed. 


Thanks again! 

As far back as I can remember, we applied fertilizer through the drill when planting small grains. The drills all had the fertilizer hopper, from the Van Brunt, right up through the 7000 series.

When I moved up to a no till drill a few years back, I couldn't find one with fertilizer. I've never seen one. I even wondered if they didn't make them. But the book with this drill (1590, I think is the model) I believe shows that option.

I can't imagine the seed mechanism would feed fertilizer satisfactorily, but I've never tried it. I bought a fertilizer spreader.

Thanks for the feedback.

Spreading it would be the simplest but since it's existing dryland haystands I'd like to do, I'm at the mercy of waiting / praying for a decent rain immediately after application otherwise I've wasted my money....

An air seeder would be ideal as well but I'm limited on tractor size / HP.

Good day!

I purchased a John Deere 750 drill, last 4 digits of the S/N - 9393, and am trying to determine the year of manufacturing.

According to my local dealer it's in the 1990 - 1994 range but couldn't narrow it down from there.

Anyone else know a way to narrow it down?


TIA

Strip tillers put 2or3 kinds of fertilizer in furrow and follow with planter often using pop up with seed and /or sidress with another opener for row crops.The Crosslot system from Australia blows seed and fertilizer into a shoe on each side of a large coulter opener putting them about 2" apart. All too complicated and expensive for 7" row spacing. The old drills used 2 delivery tubes to the operer but I'm not sure how they kept the seed and fertilizer separate in the furrow. AC used to claim they could put the fertilizer under the seed ,possibly a model 715 seed and fertilizer drill. I surface spread fertilizer in the spring and use stabilizer for N on hay and pastures.
