I will be honest, ryegrass makes a beautiful turf grass, and one that many people in our area overseed with in winter months to maintain a lush green lawn when all other grasses are dormant. The cut the 72 left in this limp, moisture laden grass looked extremely manicured, nothing left standing, and no clippings left inside the cut. I'll try to get a photo when it stops raining. I've cut with my XR-7 and VX4 side by side, and would need to flip a coin between which looked best. I would say if the XR-7 had the same size discharge, and equal hp, there would be no difference in mowing the thick ryegrass I cut, but the way it was, by being so thick and large, the XR-7 cannot move it out the smaller discharge fast enough, which in return kills the engine power.
