A Bucket Loader is a childs Teeter Totter with a few pieces added in. My big war Wagon inspired me to add this here because many of us get frustrated sometimes in solving math and lift or dirt work problems. We have learned many of the answers before we ever learned 2+2=4 on the playground. We just didn't realize it.


When 3 year-old, 50lb Johnny sat down on a Teeter-Totter with 90lb Suzy on the other end, he didn't realize it but he was learning about lift & load, torque, force thru a lever, and how a "cheater-bar" works.
All these factors are part of a bucket loader.
Neither Johnny, nor Suzy were going to enjoy the ride, because Johnny, sitting the same distance from the center of axis (fulcrum) at 50 lbs, was NOT going to lift big Suzy. They aren't Balanced. Johnny couldn't add wheel weights, Suzy wasn't going to lose weight and its going to take Johnny years to equal Suzy's weight.
Math and Physics are at play here. The force they each apply to the arm is the product of
their weight x their distance from the axis. If Johnny can sit further away than Suzy or Suzy closer
than Johnny, they can find balance and have a fine time.

#2 When they are balanced, the SUM of their weights and all that's attached to the axis is applied to the axis. For us this could be the front tires and spindles or entire GT frame depending on the location of the bucket framework parts.

#3 For every action, there is an equal and opposite reaction. (Law of physics 1 or 2?) At balance, the raising and lowering action is created by each alternately pushing against the ground with their feet.

A loader as well as other implements are just several of these lessons all tied together and can be intimidating and frustrating at times. Its not always convenient or practical to move Suzy and Johnny back and forth to solve the problem. That's where basic Math comes in.

In all cases we are dealing with FORCE. If we can keep stuff simple, then, when we ad hydraulics or Horsepower to help manage the force it all becomes easy and like Suzy and Johnny, fun.

I hope this has helped us solve the next head-scratcher-----Lee

OK but if a chicken lays an egg on a picket fence do flapjacks still fly in October?

Better question is

If you Cross a male Bulldog with a female poo-Zhu do you get BullSh.t ?

Yeah, and we all know that Pi r round, not square!

But seriously, I like your explaination of the balance.
