Tractor operation

The device was tested in field situations (operations using agricultural an tractor), which assessed its response to the excitement produced by agricultural tractor and the ability to transfer the data collected to a base station located in a remote position from the tractor operation. 

The remote data collection system allowed the tractor operations performed to be monitored in real time and in a remote position from the field work, demonstrating that the communication system adopted meets the requirements inherent to agricultural tractor operations. 

Bed systems make best use of the available land and give good access to the crop for all tractor operations. 

EXCEPTION A truck tractor operated as a single unit is not in an out-of-service condition for an inoperative rear turn signal when the turn signals located on the front are visible from the rear.

Description of hazard. Tractors are versatile tools that can be used for many different tasks. Unfortunately, when used improperly, tractors can and do cause many severe injuries and fatalities. Many accidents are similar, such as rollovers, flip-overs, and back-overs. Most tractor incidents are caused directly or indirectly by operator error—bad judgment, unnecessary haste, or carelessness. In many cases, tractor operators work independently without much supervision, so operators must understand and buy into the importance of safety. To promote this safety culture, management must stress safety on a regular basis. Common hazards and accidents in tractor operation of are ... 

Common controls. Tractor safety has improved greatly over the years. Rollover protective structures, seat belts, improved guarding, enclosed cabs, electronic controls, stability sensors, and climate control have all contributed to making tractor operations safer and more comfortable.

Drivers of trailers are responsible for safely backing a trailer into the dock well. The trailer must be aligned properly so that it is spotted properly. At this point the operator may elect to leave the cab attached to the trailer or lower the landing wheels and spot the trailer on an approved pad. The tractor operator should properly place the wheel chocks in front of the trailer wheels to prevent any movement of the trailer. Each time a forklift enters and exits a trailer that has been spotted at a dock, the impact from this movement can easily cause the trailer to move forward. As often happens, the trailer could prematurely pull away from the dock. The lift truck could fall between the dock and truck or be left in the back of the moving trailer. Many trailer truck operators, however, are not accustomed to properly placing wheel chocks against trailer wheels. Lift truck operators erroneously assume that the wheels are chocked because that is the job of the trailer truck operator. 

Hydrostatic Transmissions. The most recent use of hydrauhc power has been in hydrostatic transmissions which are used in many self-propelled harvesting machines and garden tractors and in large tractors and constmction machines. Apphcations in tmcks for highway operation also are being developed. No clutch is used and no gear shifting is involved, thus this type of transmission could be called automatic, but in all other respects the hydrostatic transmission has no similarity to the hydrokinetic automatic transmission (16). 

Less mechanization is used on smaller tracts of individually owned land, where the terrain is mountainous or otherwise difficult to reach, or where thinning as opposed to clear-cutting is the preferred silvicultural practice. The harvesting operation maybe done by the landowner or small contractor using chainsaws and tractors. In some operations where minimal damage to the forest is critical, horses may be used. Sale of pulpwood to the mill operation is usually through dealers. 

Another auxiliaiy unloading system that has proven to be very effective and efficient involves the use of moveable, hydraulically operated truck dumps located at the disposal site. Operationally, the trailer is backed up onto one of the tipping ramps, with or without its tractor. The back of the trailer is opened, and the unit is then tilted upward until the wastes fall out by gravity. The time required for the entire unloading operation typically is about 5 min per trip. 

Mineral Oil Hydraulic Fluids. Populations with potentially high exposures to mineral oil hydraulic fluids include all occupations that maintain hydraulic equipment including automobile, truck, and tractor mechanics, mechanics employed by heavy industry and mining operations to repair and maintain hydraulic equipment, and other maintenance workers involved with the repair and maintenance of hydraulic systems. The number of workers with potentially high exposures to mineral oil hydraulic fluids is expected to be very large. 

A field operator exposure study was designed to accommodate the chemical properties and the use pattern involved in the treatment of potato crops for protection against the Colorado potato beetle. Fifteen farmworkers experienced in the use of tractor-drawn sprayers for application of crop protection materials to crops were selected. All were adult males. To avoid production of a large quantity of treated potato crop prior to registration of the product for sale, the trials were performed on stubble fields after harvest of winter wheat crops in a potato-growing area of southern Ontario. This allowed the use of typical farm spray equipment and a typical duration of exposure for a complete shift of work.

For large scale operations, some nurserymen mount a spray ring on a trailer, pulled by a light rubber-tired farm tractor. Others mount the entire outfit, including a 5 gallon drum, directly on the tractor with the spray boom set just forward of, and in full view of, the driver. 

There has already been a notable trend in the past three or four years toward the utilization of propane and butane directly as motor fuel. In 1950 over 100,000 farm tractors (18) were converted to these fuels, and a number of urban bus operators announced the purchase of busses to be fueled with propane. It is felt, too, that the nonitinerant trucking operator will in many cases find it advantageous to convert to propane or butane when assured of engines that can take full advantage of the superior quality of these fuels, and once he realizes that an adequate supply can be had.
