preventive maintenance system, that is, according to a certain period of time for a major overhaul
or replacement of parts, and maintenance cycle is determined based on past statistics down, so
called regular maintenance.
With the development of agricultural machinery and equipment also will be the development of
diagnostic technology and diagnostic technology and equipment become more comprehensive and
simple. As in previous tests measure the power of hydro-power tractors, followed by the
development of the simple mechanical device to a portable electronic dynamometer dynamometer,
so that many can only be qualitative not quantitative, will be part of the fault is more clear
conclusion, reducing maintenance blindness and materials, human waste. This method of repair
according to the state called predictive maintenance, which replaces the previous regular
maintenance and corrective maintenance, it is different from regular maintenance: a maintenance
activity is the time to make repairs, a decision is the status of maintenance activities maintenance.
Predictive maintenance over preventive maintenance has the following four advantages: one is to
reduce the mechanical cause of the disaster; second is to increase the running time; third is to
reduce maintenance time; fourth is to improve productivity. However, the absence of defects in the
detector to determine the method, or greater than the cost of diagnostic equipment, diagnostic
equipment, the resulting revenue, the appropriate use of predictive maintenance approach.

2, maintenance of agricultural machinery from the economic side, that is, the use of
equipment, maintenance, updates can only be the basis of economic life. Economic life is the
device also has a production capacity, but because of tangible and intangible loss, the economic
decline in the use of equipment, if you continue to use this equipment, will result in economic
losses. That is, to a certain time due to equipment operating costs rose sharply, it must be repaired,
so as to ensure the reasonable expenses of equipment under normal operation. Equipment once per
cycle so, the cost to increase over the previous number, operating cycle to be shorter. After several
cycles to update the equipment must be considered.
3, maintenance of agricultural machinery from the management side system, economic
operation and management of all activities in pursuit of the objectives, operation and management
of maintenance of agricultural machinery is also around the central goal of economic efficiency to
carry out activities. This requires use of economic theory and methods of value engineering
principles to study maintenance techniques economic policy measures, the establishment of
evaluation index system of economic results to predict the remaining life of equipment and
determine the best life, life, life cycle cost of equipment analysis, equipment repair, rehabilitation
and upgrading of the analysis and evaluation, select a combination of technical and economic
optimal scheme for the maintenance decisions.
With the current agricultural development toward miniaturization and the rapid increase in
agricultural holdings, agricultural maintenance market has also been a rapid development, but
there has also been some negative effects, quality of service during the frequent incidents of
disputes and quality, against the the interests of farmers. To prevent and reduce this from
happening, in addition to the relevant departments to strengthen management of agricultural
machinery maintenance market, the farmers for maintenance of agricultural machinery also be
rational and sensible, and effectively improve the ability to protect themselves and enhance human
rights awareness. Common accidents are as follows:
