The disk harrow is used first to slice up the large clods left by the mould-board plough, followed by the spring-tooth harrow. To save time and fuel they may be pulled by one tractor; the disk hitched to the tractor, and the spring-tooth hitched to, and directly behind, the disk. The result is a smooth field with powdery dirt at the surface.
Harrows, whether spring tooth, spike tooth or disc harrows can have a drag connection or have a 3 point mounting. A drag harrow is pulled and cannot be backed up. Three point implements can be raised and lowered hydraulicly and maneuvered more easily. A spring-tooth harrow is a type of harrow, and specifically a type of tine harrow. It uses ...

If an impeller has only a few blades (i.e a large pitch), it will result in less lift force and in a similar manner for more blades (i.e. very low pitch), there will be high drag force. Blade solidity should not be confused with rotor solidity , which is the ratio of the total area of the rotor blades to the swept area of the rotor.
The first known lawn mower had a cylinder cutting gear made of iron. [citation needed] It was used to mow sporting grounds and wide-ranging gardens.As manufacturers changed the design and structure of mowers, the cutting mechanism also developed and evolved into several varieties, including cylinder/reel blades, deck blades, mulching blades, and lifting blades.
It translates the rotary power from the wind blades to the up-and-down motion of the pumping arm. In automotive or truck steering systems, the Pitman arm acts as a linkage attached to the steering box (see recirculating ball ) sector shaft , [ 1 ] it converts the angular motion of the sector shaft into the linear motion needed to steer the wheels .
