I found a 16 row (I think its 16) older Moline seed drill for $375. He said he planted grass seed with it last. My question is, can I plant brassica seed and other types of seed with it?
You can find a lot of information on the internet with searches but you need a better decription or model number. I would first try to gather some information from the seller basically find out what he knows.
Getting old. Sold the ranch. Sold the tractors. Moved back to the city.
My Minneapolis Moline P3-6 drill (10-ft wide, 20 drops, 6" row spacing) had a pair of grass boxes for planting small seeds (grasses, alfalfa, etc). You can see those two small grass boxes attached to the front of the larger boxes for larger seeds (oats, wheat, etc) and/or granulated fertilizer. I bought two of these old steel wheeled drills for $275 from a neighbor and used parts from both to make one working drill. Took several months of part time work to clean up the rusted parts and make the drill look pretty.
Normally, this arrangement plants grass seed in rows. If you want a solid stand of grass instead of rows, you can modify the drill as shown in this photo. I moved the grass boxes to the rear of the drill and added a pair of two-bounce seed chutes to distribute the seed in a line rather than in 20 rows.

Looks OK. It's stored in a shed--less rust.
There has to be some way to lift the disc openers out of the ground while making turns. One of the old Minneapolis Moline drills I bought had a pair of trip clutches for this task. Pull the ropes once and the openers lift out of the soil. Pull them again and the openers drop into the soil.
The other drill had manually raised openers. I modified that one by adding a hydraulic cylinder to raise the openers.
I can't figure out from the photo you posted what kind of lifting gear that drill has. I'd check this out before buying.
