Drawbar

A drawbar is a metal piece with holes bored into it. It connects with both of the lower lift arms of a three-point hitch. Its purpose is to allow the user to connect machinery to the bar for towing purposes.

Hydraulics

Pressurized oil in hoses allow a tractor's hydraulic system to operate. The hydraulic connectors raise and lower pieces of farm equipment.

Power take-off

A power take-off, or PTO, consists of a long bar that connects the tractor with the equipment. The power take-off spins rapidly, using power from the tractor to automate the attachment. A PTO is very dangerous, so it's important to keep all shields in place around it.

Weights

Weights, usually metal, placed on the front, tires or rear of a tractor give the tractor extra stability and pulling power. The weights are not permanent attachments, but the farmer usually leaves them on the tractor year round.

Grousers or grouser bars

Grousers or grouser bars are attachments added to tracked equipment to give the crawler tractor more gripping power.
