At 2,500 pounds (1.1 t), the 9N could plow more than 12 acres (4.9 hectares) in a normal day pulling two 14-inch (360 mm) plows, [3] outperforming the tractive performance of the heavier and more expensive Farmall F-30 model. [3] The hitch's utility and simplicity have since made it an industry standard.
Here the beam is hinged at a point almost above the point of the share. The bottom is held in the normal position by a set of springs or a hydraulic cylinder on each bottom. [citation needed] When an obstruction is encountered, the plough bottom hinges back and up in such a way as to pass over the obstruction, without stopping the tractor and ...

Most such tools will break up and turn over surface soil to a depth of 15–20 cm (6–8 in), whereas a subsoiler will break up and loosen soil ...
The screw itself should be drilled a minimum of 1" into the concrete to hold effectively and a maximum of 1-3/4" or the threads will wear and will lose holding power. Ideally 1-1/4" to 1-1/2" of screw thread in the concrete. [1] So for example, if a 1/2" board is being screwed onto the concrete, a 1-3/4" to 2" concrete screw should be used ...
Plow Harness. Similar to wagon harness but without breeching, used for dragged loads such as plows, harrows, canal boats or logs. This style is also used on the leaders in a team of animals pulling a vehicle. The traces attach to a whippletree behind the horse and this then pulls the load (or in larger teams may attach to further whippletrees).
