右边最远的踏板是油门脚踏板。与汽车不一样，它也可以通过手动操纵杆控制。这即可以让车辆在田间工作时保持稳定的速度，也可以通过轴或皮带为拖拉机后面的挂件提供持续的动力。油门脚踏板让驾驶者在道路作业时有驾驶汽车那样的感觉。这是现代拖拉机的一个特点，以前的拖拉机通常不会这样。在英国，拖拉机在路上行驶时，只能使用油门脚踏板来控制发动机的速度。
多数拖拉机都可以将动力传到连接的挂件上，像压捆机，锯木机和割草机等。早期的拖拉机通过装在滑轮上的皮带将动力传到挂件上。现代拖拉机使用取力器轴（PTO）将旋转动力传递到固定或拖曳在拖拉机上的挂件上。现在，几乎所有的拖拉机都可以向外提供液压和电能。
传统的条行播种拖拉机（中耕拖拉机）不带翻车保护系统
现代拖拉机都带有翻车保护系统（ROPS），拖拉机翻车时就不会碾压倒驾驶者。对露天拖拉机来说，这点更重要，他们的ROPS通常是延伸到驾驶座上的一束钢带。如果是带驾驶室的拖拉机，ROPS是驾驶室的一部分。在没有ROPS以前，许多驾驶者在拖拉机翻车后被压死。这时的露天拖拉机，采用的是三轮设计，两个前轮靠的比较近，而且角度向内冲着地面，非常危险。拖拉机在陡坡上行驶时，驾驶员经常因翻车而被压死。荷兰于1960年首先在法律上规定要求在拖拉机上使用ROPS。
农机具通过挂钩或三点式悬挂机构连接在拖拉机上，三点式悬挂机构是由亨利·福格森发明的，从1960年开始，就成为拖拉机的一个标准。连在三点式悬挂机构上的农具，通过操纵液压手柄，可以提升或降低。连在三点式悬挂机构上的农具通常完全由拖拉机支撑。
拖拉机除了在农场中使用外，在其他许多地方，我们也可以发现它的存在：大学的园林系，公园等，高速公路的工作人员经常将喷枪钢瓶用带子固定在拖拉机的一侧，风钻/空压机牢牢地固定在取力器轴上。
通用的挖掘装载机左边是挖掘机，铲斗/刀片在右边。拖拉机最常见的变种是“挖掘装载机”，其名字中包含这样的信息，装载机在前面，挖掘机在后面。当装载机和挖掘机永久连在一起的时候，就不叫拖拉机，因为他们基本上不承担拉东西的功能，因此也没有取力器轴。当挖掘机被固定上以后，通常上面安装一个可旋转的座椅，操作者工作时可以面对被操作对象。移动的挖掘机上几乎都会装一个单独的座椅。
拖拉机的耐用性和发动机功率使得它最适合承担工程任务。拖拉机上经常安装一些工程工具，如推土机、推土铲，转载设备、铲斗、耕地设备、收获机等。推土机和铲斗经常装在拖拉机的前面，拖拉机安装工程工具以后，通常取名为工程车辆。
推土机通常是履带式拖拉机，前面装有刀片，后面装绳索绞盘。推土机是动力非常强大的拖拉机，和地面的接触非常好，其主要的任务就是推或拉东西。
推土机一直在不断发展，新产品越来越多，并具备以前拖拉机所不具备的功能。装载机就是一个例子，他用大的铲斗替代原来的刀片，并用液压臂来提升或降低铲斗，因此可以很容易捞起泥土、岩石和松软的材料并把他们装到卡车上。
前面装载式装载机和装载机是带工程工具的拖拉机，有两个液压动力的臂，分别装在前机舱的两侧；还有一个倾倒设备，其实就是一个开口较大的铲斗，也有的安装的是平板叉或打包机。
推土机的改型品种还包括将设备做得更小，以便在运动受到限制的狭小区域里工作。还有小轮装载机，正是的名称是滑动转向装载机，还有一个“山猫“的绰号。它特别适用于在有限的空间里进行的挖掘工程。
战后，EPA拖拉机仍然流行，并不单是农用机械，还被一些没有取得驾照的年轻人当作汽车。EPA拖拉机在法律上被视为农用机械，年龄满16岁的人只需要拖拉机执照即能驾驶。法律上的漏洞最后被弥补了，新的EPA拖拉机被禁止被生产，但是原有的仍然是合法的；有些并被炒到了高价，EPA拖拉机的被迫停产也引发了一些爱好者的抗议。
拖车头是一种拥有大马力发动机和数根车轴的重型机械。拖头是用来拉动较长的挂车，多数用来长途运输。在英国这类“拖拉机”经常被称为"artic cab".
1908年(清光绪三十四年) .黑龙江巡抚程德全奏请清政府批准，花了22250两白银购进两台拖拉机，由瑞丰公司经营，在讷河的讷漠尔河南段自行收价代垦。这是中国最早输入的农用拖拉机（当时称“火犁”）。
Four-wheel drive tractors began to appear in the 1960s. Some four-wheel drive tractors have the standard "two large, two small" configuration typical of smaller tractors, while some have four large, powered wheels. The larger tractors are typically an articulated, center-hinged design steered by hydraulic cylinders that move the forward power unit while the trailing unit is not steered separately.
In the early 21st century, articulated or nonarticulated, steerable multitrack tractors have largely supplanted the Caterpillar type for farm use. Larger types of modern farm tractors include articulated four-wheel or eight-wheel drive units with one or two power units which are hinged in the middle and steered by hydraulic clutches or pumps. A relatively recent development is the replacement of wheels or steel crawler-type tracks with flexible, steel-reinforced rubber tracks, usually powered by hydrostatic or completely hydraulic driving mechanisms. The configuration of these tractors bears little resemblance to the classic farm tractor design.
The power produced by the engine must be transmitted to the implement or equipment to do the actual work intended for the equipment. This may be accomplished via a drawbar or hitch system if the implement is to be towed or otherwise pulled through the tractive power of the engine, or via a pulley or power takeoff system if the implement is stationary, or a combination of the two.
The drawbar system necessitated the implement having its own running gear (usually wheels) and in the case of a plow, chisel cultivator or harrow, some sort of lift mechanism to raise it out of the ground at turns or for transport. Drawbars necessarily posed a rollover risk depending on how the tractive torque was applied. The Fordson tractors (of which more units were produced and placed in service than any other farm tractor) was extremely prone to roll over backwards due to an excessively short wheelbase. The linkage between the implement and the tractor usually had some slack which could lead to jerky starts and greater wear and tear on the tractor and the equipment.
Drawbars were appropriate to the dawn of mechanization, because they were very simple in concept and because as the tractor replaced the horse, existing horse-drawn implements usually already had running gear. As the history of mechanization progressed, however, the advantages of other hitching systems became apparent, leading to new developments (see below). Depending on the function for which a tractor is used, though, the drawbar is still one of the usual means of attaching an implement to a tractor (see photo at left).
Some tractor manufacturers produced matching equipment that could be directly mounted on the tractor. Examples included front-end loaders, belly mowers, row crop cultivators, corn pickers and corn planters. In most cases, these fixed mounts were proprietary and unique to each make of tractor, so an implement produced by John Deere, for example, could not be attached to a Minneapolis Moline tractor. Another disadvantage was mounting usually required some time and labor, resulting in the implement being semipermanently attached with bolts or other mounting hardware. Usually, it was impractical to remove the implement and reinstall it on a day-to-day basis. As a result, the tractor was unavailable for other uses and dedicated to a single use for an appreciable period of time. An implement generally would be mounted at the beginning of its season of use (such as tillage, planting or harvesting) and removed only when the likely use season had ended.
Almost every tractor today features Ferguson's three-point linkage or a derivative of it. This hitch allows for easy attachment and detachment of implements while allowing the implement to function as a part of the tractor, almost as if it were attached by a fixed mount. Previously, when the implement hit an obstacle, the towing link would break or the tractor could flip over. Ferguson's genius was to combine a connection via two lower and one upper lift arms that were connected to a hydraulic lifting ram. The ram was, in turn, connected to the upper of the three links so the increased drag (as when a plough hits a rock) caused the hydraulics to lift the implement until the obstacle was passed.
Modern tractors have many electrical switches and levers in the cab for controlling the multitude of different functions available on the tractor.
Modern farm tractors usually have four or five foot-pedals for the operator on the floor of the tractor.
Many functions once controlled with levers have been replaced with some model of electrical switch with the rise of indirect computer controlling of functions in modern tractors.
The three-point hitch was controlled with a lever for adjusting the position, or as with the earliest ones, just the function for raising or lowering the hitch. With modern electrical systems, it is often replaced with a potentiometer for the lower bound position and another one for the upper bound, and a switch allowing automatic adjustment of the hitch between these settings.
For the ROPS to work as designed, the operator must stay within its protective frame. This means the operator must wear the seat belt; not wearing it may defeat the primary purpose of the ROPS.
For small-scale farming or large-scale gardening, some planting and harvesting implements are sized for CUTs. One- and two-row planting units are commonly available, as are cultivators, sprayers and different types of seeders (slit, rotary and drop). One of the first CUTs offered for small farms of three to 30 acres and for small jobs on larger farms was a three-wheeled unit, with the rear wheel being the drive wheel, offered by Sears & Roebuck in 1954 and priced at $598 for the basic model.
From 1924 until 1963, Farmalls were the largest selling row-crop tractors.
Visually, the distinction between a garden tractor and a lawn tractor is often hard to make - generally, garden tractors are more sturdily built, with stronger frames, 12-inch or larger wheels mounted with multiple lugs (most lawn tractors have a single bolt or clip on the hub), heavier transaxles, and ability to accommodate a wide range of front, belly, and rear mounted attachments.
The term "tractor" (US and Canada) or "tractor unit" (UK) is also applied to:
