Some Essential Features Of A Modern-Day Farm Combine

A farm combine is an indispensable farming machine to modern agro-allied companies. Many farm combines are currently used to perform a range of functions on the farm. These functions include some of the most essential processes of harvesting crops and haven to subject the crops harvested to further processing. Due to such functionalities, many modern farm combines are manufactured to come with several features. Many of these features are based on the failures of early farm combine systems.

Some Essential Features of Modern-day Combine Systems

1). They are used to stop rotor loss: In farming rotor losses invariably lead to lost efficiency in the field. Many previously produced farm combines were very notorious due to the extent of losses they caused due to their poorly conceived rotor designs. however, modern-day ingenuity has led many combine manufacturers to re-imagine the process. Modern-day farm combine machines are now being made with concave systems rather than rotors. The concave systems are used to prevent losses and can be used to stop losses due to the rotor. Furthermore, the concave systems are used for all crops and will usually need no changing. Commercial farming businesses fancy combines with concave systems because of their fast payback period.

2). They can improve the profitability of your company: Since modern farm combine machines do not need you to change your concaves, you can easily get all the efficiencies that you need. They increase the ground speed of your machine by 3 miles per hour. Furthermore, they are known to provide an increase in your threshing area by about 135%. This is used to produce a threshing efficiency and eliminates slow machine ground speeds and an overloaded separate machine section. This generally leads to increased efficiency which stimulates more productivity. With more productivity, the business can cash in on the abundance of crops harvested. This certainly leads to sustained productivity.

3). Reduced grain damage: Many modern combines come with custom concave systems. This makes it possible for you to maximise your threshing capacity to help you increase your output. This is used to produce a more effective crop threshing process compared to stock concaves. As a result, you get processed grains with fewer splits, cracks and damaged texture because of the threshing of the grains against the steel of the machine. With less grain damage, your farming business will be able to increase its income rather than continuously spending on wasteful processes.

4). The best concave systems: Many modern farm combines are known for their best concave systems. These systems have been built to enhance the field output of agricultural businesses. The manufacturers of the farm combines have been able to build the combines by using state-of-the-art and the most sophisticated engineering technology. This means that businesses now find their concave systems more productive and profitable than ever. This simply means that the business will remain profitable in the long term.

5). A versatile crop processing system: A farm combine machine is usually built with components that can be used for many brands. This means that farm combines like Case IH and John Deere would easily have all aftermarket parts in the market. This significantly minimizes the amount needed to buy unique spare components.

In , the Holt Manufacturing Company of California produced a self-propelled harvester.[7] In Australia in , the patented Sunshine Auto Header was one of the first center-feeding self-propelled harvesters.[8] In in Kansas, the Baldwin brothers and their Gleaner Manufacturing Company patented a self-propelled harvester that included several other modern improvements in grain handling.[9] Both the Gleaner and the Sunshine used Fordson engines; early Gleaners used the entire Fordson chassis and driveline as a platform. In , Alfredo Rotania of Argentina patented a self-propelled harvester.[10] International Harvester started making horse-pulled combines in . At the time, horse powered binders and stand alone threshing machines were more common. In the s, Case Corporation and John Deere made combines and these were starting to be tractor pulled with a second engine aboard the combine to power its workings. The world economic collapse in the s stopped farm equipment purchases, and for this reason, people largely retained the older method of harvesting. A few farms did invest and used Caterpillar tractors to move the outfits.

Tractor-drawn combines (also called pull-type combines) became common after World War II as many farms began to use tractors. An example was the All-Crop Harvester series. These combines used a shaker to separate the grain from the chaff and straw-walkers (grates with small teeth on an eccentric shaft) to eject the straw while retaining the grain. Early tractor-drawn combines were usually powered by a separate gasoline engine, while later models were PTO-powered. These machines either put the harvested crop into bags that were then loaded onto a wagon or truck, or had a small bin that stored the grain until it was transferred to a truck or wagon with an auger.

In the U.S., Allis-Chalmers, Massey-Harris, International Harvester, Gleaner Manufacturing Company, John Deere, and Minneapolis Moline are past or present major combine producers. In , the Australian-born Thomas Carroll, working for Massey-Harris in Canada, perfected a self-propelled model and in , a lighter-weight model began to be marketed widely by the company.[11] Lyle Yost invented an auger that would lift grain out of a combine in , making unloading grain much easier.[12] In Claeys launched the first self-propelled combine harvester in Europe;[13] in , the European manufacturer Claas developed a self-propelled combine harvester named 'Hercules', it could harvest up to 5 tons of wheat a day.[14] This newer kind of combine is still in use and is powered by diesel or gasoline engines. Until the self-cleaning rotary screen was invented in the mid-s combine engines suffered from overheating as the chaff spewed out when harvesting small grains would clog radiators, blocking the airflow needed for cooling.

A significant advance in the design of combines was the rotary design. The grain is initially stripped from the stalk by passing along a helical rotor, instead of passing between rasp bars on the outside of a cylinder and a concave. Rotary combines were first introduced by Sperry-New Holland in .[15]

In about the s on-board electronics were introduced to measure threshing efficiency. This new instrumentation allowed operators to get better grain yields by optimizing ground speed and other operating parameters.
