What are the limitations of using agricultural machinery in some regions?

As someone who’s spent the last 12 years as an agricultural machinery supplier, crammed into the cabs of old tractors in remote valleys and haggling over prices with smallholder cooperatives across three continents, I’ve seen firsthand how shiny, high-tech farming equipment can look like a silver bullet for global food security. But the truth is, machinery that works flawlessly on flat, grid-patterned fields in the Midwest U.S. or the plains of northern Europe often hits a wall when it lands in many of the regions that need it most. This isn’t just a case of “it’s different here”—it’s a tangled web of physical, economic, social, and cultural limitations that I’ve navigated, broken, and reworked with every machine I’ve shipped (and sometimes had to take back). The gaps between the machinery we design and build and the reality of farming in places like western Kenya’s smallholder plots, the Andean highlands of Peru, and the rural plains of eastern India aren’t just logistical—they’re a reminder that equipment is only useful if it fits the land, the people, and the way they farm. Agricultural Machinery

The most immediate, visible limitation is physical terrain and land fragmentation, something I didn’t fully grasp until I shipped a 120-horsepower tractor to a cooperative in western Kenya in 2018. I’d heard the plots were “small,” but I pictured small as 5-acre family farms. That tractor’s first job was to till a 1.2-acre plot divided into 0.12-acre strips, each owned by a different family in the cooperative, separated by waist-high earthen bunds that held water for maize. The tractor’s 8-foot-wide tiller couldn’t maneuver around a 3-foot wide bund without tipping into an adjacent plot, damaging two neighbors’ maize seedlings and drawing a week-long standoff. Even when we tested a smaller, 60-horsepower model six months later, the bunds weren’t the only issue: the land was sloped at 15 degrees, steeper than the 10-degree maximum our engineering team had designated as safe for on-road transport. The tractor’s automatic stability control—designed for flat U.S. fields—would cut power mid-row on the slope, leaving half the plot un-tilled and forcing farmers to use hand hoes for those rows. This isn’t a one-off. A 2022 study from the Food and Agriculture Organization (FAO) found that 80% of smallholder farms in sub-Saharan Africa and South Asia are fragmented into plots smaller than 2 hectares, with average slopes exceeding 10 degrees in 60% of those regions. Our large, wide-bodied machinery, engineered for continuous, flat fields, can’t turn tightly enough, fit between plots, or traverse steep, uneven ground without causing damage or breaking down. For smallholders who rely on every inch of their land for food, that’s not a minor inconvenience—it’s a threat to their entire harvest.

Then there’s the cost, a limitation I’ve run up against so often I’ve stopped quoting full prices without first asking about a community’s access to microcredit. Last year, I met a group of 15 farmers in the Andean highlands of Peru who wanted to buy a small seeder to cut down on the 6 hours a day they spent planting quinoa by hand. The seeder we offered was priced at $1,800—seemingly cheap compared to a full tractor, but for farmers whose annual per capita income is $1,200, that’s 1.5 years of income for one machine. The FAO estimates that 75% of smallholder farmers in low- and middle-income countries lack access to formal credit, and informal lenders charge interest rates of 20-50% per year—interest rates that make even a $1,800 seeder impossible to pay off in a single harvest season. To make matters worse, many regions have no after-sales support networks. Last year, a farmer in eastern India bought a second-hand combine harvester that broke down after two seasons. The nearest technician trained on that model was 120 miles away, and parts for the combine—designed in Germany—weren’t available locally. The farmer had to use hand tools to harvest his 5-acre wheat plot, losing 30% of his crop to over-ripening. For us as suppliers, this means we can’t just sell equipment—we have to also offer financing, on-site maintenance training, and a supply of affordable local parts, costs that are hard to absorb when operating in remote regions. Many small farmers also can’t afford the fuel to run the machinery. A 60-horsepower tractor uses 8 liters of diesel per hour—enough to plant 4 acres, but at $1.20 per liter in rural Kenya, that’s $9.60 per hour, more than the daily income of most smallholders. Even machines designed for electricity, like small seed drills, require reliable grid power—something only 30% of rural sub-Saharan Africa has access to, per the International Energy Agency.

The final, often overlooked limitation is social and cultural, tied to generational knowledge and traditional farming practices. In the same Andean highlands where we sold that seeder, some older farmers refused to use it, saying quinoa planted by hand produces a better, more robust grain with a higher market price. They’d been planting quinoa by hand for 40 years, knowing exactly how deep to place each seed, how much space to leave between them, and how to tend the plants without disturbing the mycorrhizal fungi in the soil that help quinoa grow. The seeder, which was calibrated for flat, uniform plots, placed seeds too deep in the rocky, sloped soil, leading to lower germination rates. Even when younger farmers wanted to use the machine, the traditional land tenure system—where plots are passed down through families, divided among children, and often rotated annually—meant that no one wanted to invest time learning a new machine that would only work on their own small plot for a few years. I saw this play out again in western Kenya, where a cooperative bought a maize thresher that could process 50 kilograms of maize per hour. The cooperative agreed to use it for collective plots, but individual farmers still threshed their own maize by hand to avoid sharing the output. Cultural practices around labor, land ownership, and crop quality aren’t barriers to be overcome—they’re part of the farming system, and machinery that doesn’t fit those practices will sit unused in a shed, gathering dust.

As an agricultural machinery supplier, I’ve had to adapt my approach over the last decade. We now test every machine we send to a new region for at least three months with a local cooperative, not just our engineering team. Last year, we redesigned a small tractor for the Kenyan market: we narrowed its body to 5 feet (to fit between bunds), adjusted its turning radius to 10 feet, and set its stability control to turn off on slopes under 12 degrees. We also partnered with a local microcredit provider to offer repayment plans over three harvest seasons, and we train two local farmers in each region to do basic maintenance and order parts from a nearby warehouse. These changes have helped, but they haven’t fixed all the limitations. There are still regions where even a small tractor is too expensive, where the land is so fragmented that a seeder can’t be used, and where farmers prefer their traditional methods.

The key takeaway here isn’t that agricultural machinery is useless in low-income regions—it’s that it needs to be designed with those regions, not for them. We as suppliers can’t just build machines in a factory in Europe or North America and ship them abroad; we have to listen to the farmers who use them, understand the land they farm, and work with the community to create solutions that fit their reality. For us, this means ongoing partnerships with local cooperatives, investing in local maintenance and training, and being flexible enough to adapt our designs when a machine doesn’t work as intended on the ground.

If you’re a farmer in a region where machinery has failed to live up to its promise, or if you’re part of a cooperative looking to test equipment that’s tailored to your land and needs, I’d be happy to discuss how we can work together to find a solution that fits your context. We’re always looking for partners to co-design and test equipment in underserved regions, and we pride ourselves on listening more than we sell.
