life cycle of a tractor
design
construction
operating
maintenance
decommissioning
commissioning
concept
concept failure
to provide a multi purpose machine that is designed for everyday farming needs and aiding making things easier for farmers due to the ability of being able to haul heavy objects etc.
too slow
maintenance concept
A tractor should be manually checked for any issues before every use
maintenance failure
Is the maintenance manual in a variety of languages to suit everyone
size
hard to manure
construction concept
decommissioning concept
when at the end of its lifecycle the tractor can be used for spare parts for other tractors etc.
decommissioning failures
spare parts may not be up to standard
old parts may not fit new machinery
same problems may occur through all machines
operating concept
tractor should have a long operating life if looked after properly and checked before every use, also if parts are maintained it will last longer
operating failures
large machinery compacts the soil which affects the land and soil
commissioning concept
tractor should operate as designed
commissioning failures
reduces labor that can take away peoples jobs
should be built using the detailed design of the tractor
construction failures
may miss a detail of the design
hard to find the right replacements
hydraulic problems
cant be disassembled easily
hard to dispose of unwanted parts
steep steps to get into cab
some parts of the tractor are hard to clean or check
should be designed and operate under different farming conditions
may not be able to test in all conditions
bolts may not be done up tight enough
manufacturing may take longer than expected
may not be designed for certain conditions
may not be designed to lift certain weights
may not operate correctly if not using the same parts as replacements
