Tractor Pull

[grub]

so I am watching this tractor pull on ESPN (woudl you believe it). They have these tractors with 2, 3, 4 engines on them.

How do you get multiple engines to power the drive train?

Big fancy gear boxes.... Some chain drive, some gear drive.

The Unlimiteds are kinda neat but the real cool show is the Super Farm and Pro-Stock tractors. They still look like tractors and make like 2000+HP from a diesel! Plus they make cool black smoke!

The mini rods are kind of neat but I like pro-farm and antique the best.
