why tractors front,rear whells are different?
400473
The front wheels of a farm tractor are needed to steer and the rear wheels are needed for traction.  If the traction wheels were too small, the force at the tire tread would be so great that the wheels would merely spin in the soil.  Also, a large wheel can climb out of a rut easier than a small diameter wheel that would have to climb almost straight up.  Cars get stuck in mud and need to be pulled out using tractors (not the other war around).

It is basically a difference in thier behaviour in different conditions. You can get a clear picture here: http://www.affa.gov.au/content/output.cfm?ObjectID=C1C9E941-4A9C-4A04-A7A747E8CA956365

When road systems were set up, there was no desire, need or ability for different countries to communicate with each in order to establish which side of the road should be used.\n\nSo if you have two sides of the road, it's a 50-50 tossup as to which side of the road will be chosen, right?\n\nAn interesting question would be "why did country (X) choose to drive on the (right/left) side of the road?"  You can probably guess that cars generally drive on the same side that vehicles before them used ... buggies, chariots, horses, etc.  So it becomes a history lesson ... for another day ....

Pitches r different due to different environmental conditions, atmosphere taking into account the humidity level,amount of rain.\nAnd moreover,it also depends on the amount of work done on it like rolling again and again!

The basic difference is that many farms today are computerized. The farmers have to know how to operate machinery. 50 years ago, farmers and their families still had to do everything manually. That is why it was important in those days to have more male children so as to have more working hands. Now this question is almost irrelevant, even one man can operate those machines. Hope that helps.

I don't know,  Maybe because you don't have any front teeth?\n\nYou're asking the wrong category... This is Auto & Racing Sports.

scodallaro doesn't know what he's talkin' about. on a 2 tire pit stop it's the right side tires that are changed 99% of the time. so i guess that would be the outside.

Only in a company owned vehicle (such as a class A semi tractor)

The difference is getting knocked from "front" or "behind".

Well there is the trailor that goes on the back of your pick up.. there is a tractor trailer that goes on the back of the semi trucks and then there is the trailer that is a mobile home.\nPretty sure this did nothing to aleviate your confusion but isnt it fun?

when delevering supplies you need to see the terrain to see what type of vechicles you can use to transport goods some of our trucks work better than others depending on the terrain.

The first question might be right but they could use different lawn mowers that cut it in different lengths. They are designed and the mowers mow it to the specifications.\n\nJust another alternative answer.\n\nI have just done more research into this and found that the mowers aren't the one that cut the grass differently no matter which way u cut it. They have rollers that come onto the pitch that flatten the grass into a different direction giving you the effect of different shading.

A BACKING DIAGRAM?  I have never heard of that.  You just have to be TAUGHT how to back the tractor trailer up.  It takes practice, practice, practice!  Especially if you live in a state that requires several backing maneuvers to pass, like DC, for example.  They require blind side backing, parallel, "alley dock", and straight backing.  VA requires straight backing and curve backing.\n\nIf you are not in a training school in your state somewhere, I'd suggest picking up the CDL training manual from your DMV!\n\nGOOD LUCK!\n\nLM
