A tractor in Bangladesh costs five to fifteen thousand US dollars, a thresher two to five thousand, a power tiller under two thousand - still out of reach for most smallholders. The farmer working two or three bighas, whom most machinery companies actually sell to, earns a few thousand dollars a year. The math does not work, so the machinery sits on the dealer floor while the farmer rents or borrows.
Machinery companies have known this for decades. The workarounds - dealer installment schemes, moneylender financing, narrow government subsidies - never reach the full farmer population. So the market looks small when it is huge. Most farmers want modern machinery and cannot buy it, and that gap is where the real Bangladesh agricultural market lives.
The machinery companies do not have a demand problem. They have a financing problem.
