****** Block

Physics 101: I'll keep this in the simplest terms possible....
- A ****** block doubles the pulling power because at the motor (cable reel) it is still taking in the same amount. However, because it is doubled back to the object being pulled, it is pulling in the same amount of cable at HALF THE SPEED; hence double the pulling power. It's "mechanical advantage". Sit on the ground and tie a rope to a tree. Now pull yourself towards the tree with the rope. Then, attach a pulley (****** block) to the tree. Tie one end of the rope to your ankle, and pull on the other end. For the same amount of rope as you pulled in the first time, you will move half as far and will be using half the effort.
And... if your line is rated for 1,500lbs and use a ****** block and pull way 2,000lbs it will not break. You are "doubling" the line so in theory it will be twice as strong. However, because the force of firction at the pulley, it's not quite twice as strong. For arguments sake though, you will be fine.</end quote></div>
awesome thanks

I have plans to get a new Bigger polaris in the future. Hopefully sooner than later. When I get it I will probably just get the winch as a package that way if there are any problems then it is their deal.
I will keep this 500cc atv for the G/F and yard work and plowing since it is all set up. The bigger one will be my rider and stuff.

If I could just add a little info......Just be careful if your block has a double sheave, which means the pulley is 2 pieces joined at the middle... When using synthetic that seam can damage the rope at extreme pressures......If at all possible try to get a block with a single sheave(pulley is 1 piece).
