• Frame front arm straps (up ½ inch up)
• Dully runner to single (1 to 2 mph w/arm strap up ½”)
• Rear coupler blocks in lowest position (improves traction)
• Low windshield 2-3 mph faster than mid and 5-6 mph faster than tall
• Additional Idler wheels in frame 2-5 mph (based on snow conditions) saves on hifax
• 96 studs (minimum) is recommended to stop track spinning at low, mid and top speeds in marginal traction conditions (huge difference in acceleration)
