The used agricultural equipment market is not monolithic; different equipment categories operate on distinct and often asynchronous supply and demand cycles.
Real-time auction data serves as a powerful leading indicator for the health of the broader agricultural economy, often predicting trends like net farm income ahead of official reports.
The level of aged inventory on dealer lots is the most critical factor driving short-term price volatility and market behavior, forcing liquidations when high and creating supply squeezes when low.
Brand premiums, such as for John Deere, are significant for newer used equipment but erode substantially as machines age, making brand a less critical factor for older assets.
The current market landscape for several equipment categories is a direct, lingering consequence of the supply chain disruptions that originated during the COVID era.
COVID-era
Campbell identifies this period as the origin of supply chain disruptions for components like wire harnesses and chips, which led to lingering inventory imbalances.
January 2023
Cites this month as the peak for used semi-truck market values, establishing a benchmark for that market's subsequent decline.
December 2023
Notes that manufacturers of new four-wheel drive tractors began to slow production in response to decreased demand, signaling a market shift.
Summer 2024
Describes a major market event where an oversupply of used Class 8 combines on dealer lots forced a large-scale liquidation through the auction market.
Mid-2025
Highlights a period where TractorZoom's auction data for row crop tractors predicted a downturn in net farm income, running contrary to the USDA's initial optimistic projection.
February 2026
Campbell characterizes the market as bifurcated: the four-wheel drive tractor market is soft and has not bottomed out, while the row crop tractor and planter markets are rebounding with rising values and tightening supply.
▶Market Segmentation and Asynchronous CyclesApr 2026
Campbell's analysis consistently breaks down the used agricultural equipment market into distinct segments (four-wheel drive tractors, row crop tractors, combines, planters) that operate on different and often opposing cycles. He demonstrates that while one segment might be in a downturn with softening values, another can be simultaneously experiencing a rebound with tightening supply.
Investors and analysts should avoid making broad assumptions about the health of the ag equipment sector and instead focus on the specific supply, demand, and inventory dynamics of individual equipment categories to identify opportunities.
▶Dealer Inventory as a Primary Market CatalystApr 2026
A core tenet of Campbell's perspective is that the level of inventory on dealer lots is a primary driver of market behavior. He cites oversupply leading to auction liquidations for combines in 2024 and aged inventory creating price pressure on four-wheel drive tractors, while critically low supply for planters and row crop tractors is driving values up in 2026.
Monitoring real-time dealer inventory data, especially the volume of aged units, serves as a powerful leading indicator for future price volatility and buying or selling opportunities in the used equipment market.
▶Auction Data as a Predictive Economic IndicatorApr 2026
Campbell positions high-frequency auction data as a tool that can forecast broader agricultural economic trends with greater speed and sometimes greater accuracy than official government sources. He specifically notes that TractorZoom's data on row crop tractor values has historically correlated with USDA net farm income and even contradicted and corrected initial USDA projections in mid-2025.
Alternative data from platforms like TractorZoom can provide a significant analytical edge, allowing for earlier identification of macroeconomic shifts within the agricultural sector before they are reflected in traditional economic reports.
▶The Lifecycle of Brand Value and Technology's ImpactApr 2026
Campbell provides a nuanced view on brand premiums, explaining that while a manufacturer like John Deere commands a higher price on newer used equipment, this advantage erodes significantly as machines age. He also notes that new technologies with a clear ROI, like John Deere's See & Spray, can disrupt traditional depreciation curves and help equipment retain value better than older models.
Asset valuation models for farm equipment must evolve to account for the diminishing premium of brand names over an asset's lifecycle and the increasing importance of specific, efficiency-generating technologies.
