A tractor (from Latin trahere "to pull") is a device intended for drawing, towing or pulling something which cannot propel itself and, often, powering it too. Most commonly the word is used to describe a vehicle intended for such a task on some other vehicle or object. Download high resolution version (1200x1023, 483 KB)A modern farm tractor. ...

Farm tractor
The most common use of the term tractor is for the vehicles used on farms. The farm tractor is used for pulling agricultural machinery or trailers, for ploughing, harrowing and similar tasks. The classic farm tractor is a simple open vehicle with two very large driving wheels on an axle below and slightly behind a single seat (the seat and steering wheel consequently are in the center) and the engine in front of the driver with two steerable wheels below the engine compartment. This basic design has remained unchanged for a number of years, but now enclosed cabs are available for many models of farm tractor. This is a photo of a John Deere 8110. ...

There are usually four foot-pedals, for the operator, on the floor of a tractor. The pedal on the left is the clutch. The operator presses on this pedal to disengage the transmission for either shifting gears or stopping the tractor. Two of the pedals on the right are the brakes. The left brake pedal stops the left rear wheel and the right brake pedal does the same with the right side. This independent left and right wheel braking augments the steering of the tractor when only the two rear wheels are driven. This is usually done when it is necessary to make a tight turn. The split brake pedal is also used in mud or soft dirt to control a tire that spins due to loss of traction. The operator presses both pedals together to stop the tractor. For tractors with additonal front-wheel drive, this operation often engages the 4-wheel locking differential to help stop the tractor when travelling at road speeds. This article is about an automotive technology. ...

This helps provide a constant speed in field work. It also helps provide continuous power for stationary tractors that are operating an implement by shaft or belt. The foot throttle gives the operator more automobile-like control over the speed of the tractor for road work. When travelling on the road in the UK, it is mandatory to use the foot pedal to control engine speed.

Most farm tractors use a manual transmission. They have several gears which generally provide a range of speeds from less than a mile per hour up to about 25 miles per hour. Compared to other vehicles the tractor is quite slow. Slower speeds are necessary for most operations that are performed with a tractor. These slower speeds help give the farmer a larger degree of control in certain situations—such as field work. Older tractors generally require that the operator press in the clutch to shift the gears but many modern tractors can shift between certain gears without the need to depress the clutch. The former was a limitation of straight-cut gears in the gearbox, the latter an advance so that the operator can have more control over working speed than just the throttle.

A gearbox is an assembly of gears allowing the rotational speed of an input shaft to be changed to a different speed. ...
 The classic Row Crop tractor Modern farm tractors range in size from 18 to 500 horsepower (15 to 400 kW). Tractors can be generally classified as two wheel drive, two wheel drive with front wheel assist, or four wheel drive (with articulated steering). Variations of the classic style include the diminutive lawn tractors and their more capable and ruggedly constructed cousins garden tractors, which tend to range from 10 to 25 horsepower and are used for smaller farm tasks, mowing grass, and landscaping. The size - especially with modern tractors - and the slower speeds are reasons motorists are urged to use caution when encountering a tractor on the roads. http://www. ...

Modern tractors have roll over protection systems (ROPS) to prevent an operator from being crushed in the event of a rollover. This is especially important in open-air tractors. In open-air tractors the ROPS is a steel beam that extends above the operator's seat. For tractors with operator cabs, the ROPS is part of the frame of the cab. Before ROPS were required many farmers died when their tractors rolled over on top of them. Row-crop tractors, before ROPS, were particularly dangerous because of their 'tricycle' design with the two front wheels spaced close together and pointed inward toward the ground. Many farmers were killed by rollovers while operating tractors along steep slopes. ROPS were first required by legislation in New Zealand in the 1960s.

 A PTO shaft plugged into a tractor. Most tractors have a means to transfer the engine's power to another machine such as a baler or mower. Early tractors used belts wrapped around pulleys to power stationary equipment. Modern tractors use a power take-off shaft (PTO) to provide rotary power to machinery that may be stationary or pulled. Almost all modern tractors can also provide hydraulic and electrical power. In this photo a PTO shaft that is plugged into the power take off of a farming tractor is shown. ...

Farm implements can be attached to the rear of the tractor by either a drawbar or by a three-point hitch. The three-point hitch was invented by Harry Ferguson and has been a standard since the 1960s. Equipment attached to the three-point hitch can be raised or lowered hydraulically with a control lever. The equipment attached to the three-point hitch is usually completely supported by the tractor. The three-point hitch is a device used on farming tractors used for certain implements. ...

Engineering tractors The durability and engine power of tractors made them very suitable for engineering tasks. Tractors can be attached with different engineering tools such as dozer blade, bucket, hoe, ripper and so on. The most common attachments for the front of a tractor are dozer blade or a bucket. When attached with engineering tools the tractor is called an engineering vehicle. This article needs to be cleaned up to conform to a higher standard of quality. ...

Bulldozers have been further modified over time to evolve into new machines which are capable of working in ways that the original bulldozer can not. One example is that loader tractors were created by removing the blade and substituting a large volume bucket and hydraulic arms which can raise and lower the bucket, thus making it useful for scooping up earth, rock and similar loose material to load it into trucks.

A front-loader or loader is a tractor with an engineering tool which consists of two hydraulic powered arms on either side of the front engine compartment and a tilting implement.

Other modifications to the original bulldozer include the reduction in size of the machine to permit it to operate in small work areas where movement is limited. There are also tiny wheeled loaders, officially called Skid-steer loaders but nicknamed "Bobcat" after the original manufacturer, which are particularly suited for small excavation projects in confined areas. A skid loader, also called a skid steer, is a compact, low capacity machine used for pushing or lifting material and for digging. ...

Backhoe loader
 A common backhoe-loader. The backhoe is on the right, the bucket/blade on the left. The most common variation of the classic farm tractor is the loader-backhoe, also called a backhoe-loader. As the name implies, it has a loader assembly on the front and a backhoe on the back. When both the loader and the backhoe are permanently attached it is almost never called a tractor, not generally used for towing and usually does not have a PTO. When the backhoe is permanently attached, the machine usually has a seat that can swivel to the rear to face the hoe controls. Removable backhoe attachments almost always have a separate seat on the attachment itself. loader-backhoe from NOAA web site www. ...

Backhoe-loaders are very common and can be used for a wide variety of tasks: construction, small demolitions, light transportation of building materials, powering building equipment, digging holes, breaking asphalt and paving roads. Some buckets have a retractable bottom, enabling them to empty their load more quickly and efficiently. Retractable-bottom buckets are also often used for grading and scratching off sand. The front assembly may be a removable attachment or permanently mounted. Often the bucket can be replaced with other devices or tools. Asphalt is a highly viscous liquid that occurs naturally in most crude petroleums. ...
Their relatively small frame and precise control make backhoe-loaders very useful and common in urban engineering projects such as construction and repairs in areas too small for larger equipment. Their versatility and compact size makes them one of the most popular urban construction vehicles.
