Sounds like you got a solution but here is my $.02. I would go Sealmaster and one that purges grease when it is full (so you dont over grease). NP16TC perhaps? Grease it often to purge contaminants.
The other day I turned a 70’x80’ brush choked part of the yard into a dirt patch using the box blade with teeth. Kids pulled a big old hay rake behind the quad to filter out the sod chunks. Amazing how much work these things can do in a short time.
