Bill of Materials
- Wheels
- Shaft collars, 1-7/8", double split - 4 of them - [1] - $6.75 each
- Tires
- Tire chain quick links, 18 per wheel - 1/4" - [2] - 60 cents each
- Wheel control
- 50/50 divider to allow equal flow to front and back wheels when front wheels come off the ground while doing earth digging with loader - [3] - $88
Bill of Materials for Industrial Counterparts
- One tire and rim - a flat proof one - costs $500 for skid loaders - [4]. Compare to $5 used truck tires with $35 for open source chains - under $50 for a tire. The latter affords the same traction, at 10-100 times less cost, depending if you count the chains or not.
- Which is more cost effective over a lifetime?
