You could leave soil strips between raised rows. Get yourself a gizmo in Agri Supply that allows you to bolt various plows and cultivators to it. Get a couple disc hillers, big diameter, and mount them at about 45 degree angles directly behind the rear wheels to make your raised rows. Attached is a picture of my rig I had on my 4010 (2019E by today's JD nomenclature). No longer needed it after creating my raised rows because I went no till.
To get rid of your grass, either put down a lot of newspaper and cardboard and new soil on top or attach a big turning disc to that gizmo from Agri Supply. However, you'd need a trailing wheel to help hold it in place. Agri Supply probably has a turning disc with trail wheel for the 3ph. I'd used a Gravely with a rotary plow to turn over some heavy fescue grass when I created my 50x75 garden originally and used an old JD M soil ripper on it prior to running the disc hiller rig to make 20 raised rows.
You could also just make some long raised rows with some 2x6s, two high. Then, you wouldn't be able to use your tractor to cultivate it to remove or to cover weeds. Depends on how big you want your garden. I had the 20 rows at 50' long and did the weeding and mulching on my knees and hands, bringing huge loads of mulch down in my mulch hauler (picture attached).
Got congestive heart failure and had to give up my big garden and have raised beds up here near the house.
Oh, I've a 2025R now but primarily use it for bush hog and MacKissic
chipper/shredder now and snow moving with FEL and backblade. Still have the carryall that I use occasionally to go get limbs. Wish I could have gotten a 2019R. (My 4010's U joint behind the engine disentegrated at 660 hours and 9 years.)
