Selection and Economics of Farm Machines and Equipment

The selection and economics of farm machinery and equipment are crucial in increasing farm efficiency. Farmers, whether they own their machinery or hire them, must strike a balance between capacity, efficiency, and cost-effectiveness. This procedure includes assessing field capacity, operational efficiency, fixed and variable expenses, and the viability of custom hiring farm machinery.

Field Capacity and Efficiency

1. Field Capacity:

Field capacity is a measure of the area a machine can cover in a given period of time. It is expressed in two forms:

• Theoretical Field Capacity (TFC):
  • This is the ideal performance of a machine based on its width and speed of operation, without considering delays or inefficiencies.
  • Formula: TFC (ha/hr)=10Working width (m)×Speed (km/h)​

• Effective Field Capacity (EFC):
  • This accounts for actual field conditions, including time lost in turning, adjustments, refueling, and other delays.
  • Formula: EFC (ha/hr)=TFC×Field Efficiency

2. Field Efficiency:

Field efficiency is defined as the ratio of effective field capacity to theoretical field capacity. It takes into consideration the time lost owing to factors including operator expertise, field shape, machine manoeuvrability, and downtime for maintenance.

• Formula: Field Efficiency (%)=TFC/EFC​×100
• Typical Range: Efficiency can range from 60% to 90%, depending on the machine type and field conditions.

Cost of Operation of Farm Machines

The cost of operating farm machinery is divided into fixed costs and variable costs.

1. Fixed Costs:

Fixed costs are incurred regardless of machine usage and are related to ownership. These costs are spread over the life of the machine.

• Depreciation: The reduction in value of a machine over time. It is calculated using the straight-line method or other depreciation formulas.
  • Formula: Depreciation = Initial Cost−Salvage Value ​/ Useful Life (years)
• Interest on Investment: The opportunity cost of the capital tied up in the machine.
  • Formula: Interest= Initial Cost+Salvage Value​ / 2 × Interest Rate
• Insurance and Taxes: Costs associated with insuring and taxing the equipment.
• Housing/Storage: The cost of storing machinery when not in use.

2. Variable Costs:

Variable costs depend on the actual usage of the machine. These costs increase with the amount of work done.

• Fuel: The cost of fuel consumption during operation, which depends on the machine’s fuel efficiency.
• Lubricants and Maintenance: Costs for oil, grease, and routine maintenance like filter replacement.
• Repairs: The cost of repairing the machine, which generally increases with age and usage.
• Labor: The cost of hiring an operator or the owner’s labor during operation.

3. Total Operating Cost:

• Formula: Total Operating Cost=Fixed Cost+Variable Cost

This total cost is typically expressed per hectare, per hour, or per unit of output.

Feasibility of Custom Hiring of Farm Machines and Equipment in Nepal

Custom hiring refers to the practice of renting farm machinery and equipment instead of owning them. In countries like Nepal, custom hiring has become increasingly popular due to several factors:

1. Benefits of Custom Hiring in Nepal:

• Capital Savings: Many small-scale farmers in Nepal cannot afford to purchase expensive farm machinery like tractors, combine harvesters, or threshers. Custom hiring allows them to access these machines without large upfront investments.
• Risk Reduction: Ownership of farm machinery comes with risks, including equipment failure, downtime, and rapid depreciation. Custom hiring shifts some of these risks to the equipment provider.
• Access to Modern Technology: Custom hiring services often provide the latest machines and technologies, which farmers might not afford on their own.
• Cost-Effective for Small Farms: In a country where many farms are small, owning large-scale machinery might not be economically viable. Renting allows farmers to use machines as needed, reducing unnecessary idle time and maintenance costs.

2. Factors Supporting the Feasibility of Custom Hiring:

• Fragmented Land Holdings: Most farmers in Nepal have small and fragmented land holdings, making it inefficient to own machines that may not be in use regularly.
• Government Support: The Government of Nepal has encouraged custom hiring centers and cooperatives that provide machinery rental services. These centers offer subsidized rates for small farmers and promote the use of modern equipment.
• Cooperatives and Private Sector Participation: Many farming cooperatives and private businesses in Nepal are now involved in custom hiring services. They rent out farm machines like tractors, tillers, and irrigation equipment to smallholder farmers.

3. Challenges in Custom Hiring:

• Availability of Machines: During peak seasons like planting and harvesting, there may be a high demand for machinery, leading to shortages in available machines.
• Maintenance and Quality Issues: Rented machinery may not always be in optimal condition, which can affect efficiency and increase downtime.
• Logistics: In rural areas, transporting machinery to remote fields can be a logistical challenge, increasing the cost and reducing access for some farmers.

4. Economics of Custom Hiring:

The cost of custom hiring is generally lower than owning machinery, especially for small and medium-sized farmers. The costs typically include:

• Rental Fee: The rate per hour or per hectare, depending on the type of machine.
• Fuel Costs: In some cases, the farmer is responsible for providing fuel, while in other cases, it may be included in the rental fee.

By analyzing the farm size, machine requirements, and local rental rates, farmers can determine whether custom hiring is more economical than owning.

Conclusion

Farm machinery selection and economics are determined by a variety of criteria, including field capacity, machine efficiency, fixed and variable expenses, and operational requirements. In Nepal, custom hiring has emerged as a viable option for small and medium-sized farmers who cannot afford to purchase pricey equipment. Custom hiring services, with sufficient government assistance and infrastructure, can help increase farm production, cut expenses, and offer access to current farming technologies.
