Planting to stabilize a new sloping dirt lane

Soon I will have about 60 feet of 8' wide lane at 7.5 degrees slope. Loamy clay soil.

I want to seed it with something that will stabilize it, stay short, and not be slick for the tractor.

Any ideas?  Thanks!

While I don’t have a grass suggestion for you I can tell you what I wish I done on my sloped area I cleared. Water it after seed and get it growing ASAP. I have 1000s of dollars in topsoil gone because I waited on rain and good light rains didn’t come. It was hardcore rushing rain. I’m trying to fix this still. Whatever it would have cost to buy hoses sprinklers seed 3x would’ve been a great investment that I had to do in the end anyways. So I throughly recommend supplementing the water and get some roots down

Dwarf Perennial Ryegrass is a possibility for the lane. Has anyone planted it? Any nightmares like it becoming invasive?

I have not grown Dwarf Perennial Ryegrass though I have read that it goes dormant in the summer.  This makes me think that this time of year would be hard to get it established.

I am in Texas so I don't know how this grass would work for your area so I suggested that you might want to research it. If it grows in Montana seems like it would work for you:
