Cam tractors be used for other jobs besides farming?

Hello? Tractor pulls. 

Of course.  They can be used to pull things; logs, etc.  

Absolutely tractors have a shaft on the back of them that you can attach all kinds of different machinery to let's take the use on a golf course for instance. You can hook a lawn mower up to it. You can hook a fertilizer spreader up to it called a vicon. You can hook a machine up to it called an aeration device which pokes holes into the soil.

You can use a tractor at a construction site to drive a generator. Or to hook a compressor up to spray paint with. Basically a tractor is a mobile unit with a shaft that can be hooked to about a million different tools. In addition to pulling and pushing things.

A tractor is an engineering vehicle specifically designed to deliver a high tractive effort (or torque) at slow speeds, for the purposes of hauling a trailer or machinery such as that used in agriculture, mining or construction.  (wikipedia)

you see thousands of tractors pulling trailers on the highway. You know them as tractor-trailers.

Tractors are very versatile.

For instance, there's a feature called a power takeoff. It provides rotation for things like blowers, log cutters, blowers, pumps, etc.

You can convert a tractor to become a cotton picker, etc.
