How much does the Cat 836K landfill compactor smoosh the earth? Allow me to explain with amateur maths: — Caterpillar 836K Operating Weight = 123,319 pounds — Number of Wheels = 4 — Spikes / Wheel = 40 — Total Spikes = 160 — Total Spikes Contacting Ground = 80 — Load / Spike = 3,083 pounds — Spike Area = 8 square inches — Ground Pressure / Spike = 385 psi — Trained Amateur Boxer Punch = 300 psi — Therefore, this machine is like hundreds of amateur-trained boxers punching the ground.
