Investing in a sprayer: guidelines to assist the decisions

Published: 20 Sep 2018

Sprayers are critical implements on a broadacre cropping farm. Choosing the right sprayer and justifying its ownership cost can be challenging. Taking a structured approach to assessing your needs will help reduce the stress and uncertainty of the decision.

Key points

  • The capital invested in a sprayer is significant and a thorough assessment of the investment return should be undertaken prior to purchase.
  • In some instances, the best economic decision may be to utilise contractors for specialised spray tasks rather than own a machine suited to all tasks.
  • Alternative uses for equipment (particularly tractors used to pull a tow-behind machine) and the number of hours per annum are key determinants in the most suitable type of machine and cost of ownership.
  • Before upgrading your sprayer consider options to increase the overall efficiency of an existing machine.

Structured decision making approach

Step 1. What tasks and timelines do i need to achieve?

The targets around getting necessary spraying-based tasks completed on time vary considerably from business to business.

Some examples of spraying objectives include:

  • the capacity to complete post-emergent grass-selective herbicide application before weeds start tillering;
  • the capacity to spray a cereal crop variety in three days (rust or disease control);
  • the capacity to get chemical out within a short window of opportunity during winter; and
  • the ability to apply herbicides during late stages of crop development (crop-top).

Step 2. What will affect these timelines?

Besides physical limitations, such as a sprayer’s clearance height, the ability of your equipment to meet objectives in a timely manner will be influenced by the work rate of the machine in the paddock and efficiencies impacting on timeliness outside the paddock.

Step 3. Assessing the options: owning, using contractors or a combination

The options are either self-ownership or use of contractors. A combination of the two is also possible. The key questions to ask with respect to each of these options include the following;

Step 4. Ownership and costs: what can be justified?

Justifying an investment in a sprayer is a balance between financial and non-financial considerations. The primary financial consideration is cost of ownership, which will be influenced by the following.
