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
