Study Notes

Introduction to Agricultural Tractor and Equipment Maintenance

Maintenance is crucial for equipment to perform optimally over time, like how healthy diets, rest, and exercise maintain human health
Preventive maintenance, following manufacturer recommendations, aims to prevent equipment breakdown and ensure safe operation
Objectives of preventive maintenance include safe operation, reduction of downtime due to failures, and lowered repair costs

Preventive Maintenance Benefits

Preventative maintenance is crucial for safety
Difficulties in quantifying safety benefits as some safety measures cannot be measured in monetary terms
Expense of maintenance is a factor but can be minimized by properly performed preventive maintenance

Causes of Agricultural Equipment Breakdown

Wear from dirt, grit, and friction
Temperature extremes (hot and cold)
Moisture contamination
Physical damage
Improper operation and adjustments
Neglect of maintenance
Design or manufacturing flaws

Importance of Operator's Manual

Operator's manuals guide operators through proper procedures, indicating what to do and when
Provides information on required actions for maintenance, including: cleaning, lubricating, replacement of worn parts, adjustments, refilling fluids, oil/gas checks

Types of Preventive Maintenance

Field Maintenance: servicing, minor repairs, and adjustments during routine operation
Routine Daily Maintenance: scheduled checks (e.g., fluid checks, cleaning) performed regularly
Periodic Maintenance: tasks performed at specific intervals (hours or time periods), such as oil changes, filter replacements, and component inspections
Storage Maintenance: procedures before storing equipment for extended periods to minimize degradation and ensure readiness for the next use. This involves actions such as cleaning, lubrication, and drainage

Storage Maintenance Procedures

Cleaning the equipment
Changing engine oil and filter
Making a detailed list of required parts
Ensuring adequate time for repairs
Lubricating and maintaining all components
Draining and/or replenishing critical fluids
Preparing the equipment for storage to protect from the elements

Periodic Oil Sampling

New preventative measure involving periodic oil sampling
Oil samples are collected and sent for analysis
Helps in detecting wear and tear, contaminants, and unusual conditions
Helps in adjusting maintenance schedules and decision-making to extend usability; reduce costly downtime
