Equipment and Mechanisation

Mechanisation is not a purchase decision — it is a labour-cost decision repeated across every task. The question is never "is this machine good?" but "does this machine beat my wage rate at my hectares?" This page maps tasks to equipment by scale, and gives the buy-vs-hire rule that keeps capital from eating the cash-flow plan.

Labour hours each machine displaces come from the labour calculator; the capital goes into the farm budget.

The task–equipment map#

The tools used every week#

• Harvest knife and bucket — the single most quality-critical tool; keep them clean and sharp, sanitize between blocks in disease areas (IPM).
• Desuckering spade — flat, sharp, cut below ground level; a blunt one tears the mother corm.
• Brush cutter — handles alleys and mulch topping; blade choice matters (tri-line for grass, circular for woody).
• Mist blower knapsack — 3–5× the coverage of a compression sprayer, which is the difference between spray compliance and skipping.
• Harvest cart — most bruising happens between field and packhouse, not in it. Railed or wide-tired carts on laid alleys cut labour and losses; see post-harvest.
• Water pump and filter station — the heart of irrigation; size from the irrigation calculator.

Buy vs hire vs contract#

Annualised cost of owning = (purchase − resale) ÷ years + maintenance + fuel + storage
Compare against            = hire quote × uses per year (or crew-day cost saved)

• Buy what you use weekly and can maintain locally (parts availability beats specs).
• Hire campaign equipment and anything with tyres, engines or hydraulics you cannot fix yourself.
• Contract tasks where the operator's skill dominates the machine — spraying and aerial work especially.
