Im going to buy a 2 wheeled sulky for my new mower that im buying. I Have seen three different ones: Velke X2 (on landscapersupply), Jungle wheels and the bronco rider. I have only tried the jungle wheels I like these because they match my mower and their pretty smooth. The broncorider seems bulky but stable and built to last. You can also change out the platform when its worn out. I dont know much about the velke x2 looks like the jungle wheels to me. Whats the better out of the three. I dont want a proslide.
