I was going to say you'll need to budget at least $150. There are a few different versions of the rear liftable hitch, and I think there's only one that works for your tractor. You may need a little patience, too.
I assume you just want to pull a Brinly plow, right? Another thing to consider is the rear wheel offset. I'm not knowledgeable enough about the G-series to say if you can run the right rear wheel flipped inboard or not. I seem to remember some you can, and some you can't. I'm not sure how things would line up and sit in the furrow.
The G-series would not be my rider tractor of choice for gardening work. They're good tractors, but Gravely was almost purely marketing to lawn care and snow removal users by the time they came out, and some of the "soilworking options" are harder to find - liftable rear hitches and individual wheel brakes being the big ones.
