I borrowed a neighbors 4WD 4 wheeler this year and so far I love it. I have an older 4WD Kubota tractor with AG tires. On frozen ground it's great. Once the ground thaws, not so much. Leaves too many deep ruts everywhere, especially through woods trails where you can't take a different track to avoid going through the same area over and over collecting sap. So for me, it's a small 300CC 4WD Quad.
But ultimately, I'd rather have an Argo or Max2, if I could afford either, and had wider trails.
