Yardforce Classic 500 Wheel Spikes

These spike are a quick model that lips onto the inside edge spikes of the original wheel. they should work by just clipping them over the inside spikes on each wheel making 8 extended spikes per wheel. The 17 mm spikes are probably too long and for me they cause the mower to wobble as the spikes are lifting the mower. The smaller 10mm dual spikes are a last min(untested) modification that I think should work nicely. I'll update once i test them.

Updated with another wide stance spike for smoother ride as well as a full ring with 16 spikes.
