What style meters does it have? OEM JD vac. will work good in corn if you have rounds or small flats, won't work well with large flats over 50 lbs. (22.68 KG) per 80K seed count, just need to set the vac. accordingly otherwise. (These would be the cell meter disks.) Two different disks are available, small corn and corn (the regular disk). Small corn works with the smaller rounds and flats, regular corn is more for medium/large rounds with seed size.
Finger meters very forgiving and run (almost) everything for corn seed size. You won't have these if planter is a vac. meter, they are 100% mechanical.
Precision vac. meters (I have Esets) about the same as finger pickup in what they handle, perhaps even better. A bit overkill if you aren't putting in much per year however. Mine were upgraded OEM meters, cost me about $150 US per row to change over. (Hence the overkill statement if doing low acres per year.) If you have these the disk will be much thicker (also no cells, just holes) and the meter has a singulator and extractor pick that the OEM doesn't. The long brush will also be split into two pieces and the shorter section can be pulled out and put into a different position.
Might be able to find canola disks for such meters if you dig around and grow the stuff, I don't, 22" might be a little on the wide side but *should* work... Others on here would have more experience with that than I would.
I have a JD 1760 planter with ME2 row units on it that I have used for two years now doing around 350 ac. a year, so far none of the opener bearings have failed but will be putting on new openers this spring yet, depth wheels need a few new bearings as this planter was well used, closing wheels I replaced when I got it. Not a bad idea to keep a few bearings of each around. Nothing more annoying than a closing wheel bearing that seizes up as it will not close the trench properly and leave a ditch. A depth wheel bearing seizing will quickly be dragging a big pile of dirt, opener bearings will do the same, and if run for any length of time the opener will wear a flat spot and need replacing, also the opener blades can crack out around the hub if running high downforce, so far have not seen one do that but others have.
How do you plan on planting the corn, are you in tilled or no-till ground? No-till will take more downforce, takes a lot more with a double disk opener (planter) vs. single disk. (air seeder) due to the way the seed trench is formed. No-till I have to be able to run up to 400 lbs. per row, hard to achieve with a 3pt. mounted toolbar style planter, obviously tilled is considerably less...
For planting corn uniform depth is very important, more so than seed spacing as studies have shown, from looking at pictures does not appear yours has firmers mounted (Keetons or the likes) and if corn is for grazing or silage not likely to be much of a factor but for grain could help, however the old planter I still have didn't have any such device and put in a crop for many years and it turned out ok in tilled soil.
