Farm Equipment Lobbying Machine Paid $165M to Harvest Tariff Relief
A peer-reviewed study confirms campaign contributions statistically increase the odds of receiving tariff exemptions — and agribusiness spent a 20-year record to play that game.
The single most documented fact in this investigation is not an allegation. It is a finding published in the Cato Institute's peer-reviewed Research Briefs in Economic Policy: campaign contributions and lobbying expenditures statistically and independently increase the probability that a company receives a federal tariff exemption. The authors state explicitly that 'our federal institutions do not prevent an administration from using the tariff exemption process to reward supporters and punish opponents.' That finding forms the foundation of everything that follows.
The agribusiness sector — which includes agricultural equipment manufacturers and their dealer networks — spent $165 million on federal lobbying in 2022 alone, according to data compiled by Investigate Midwest and OpenSecrets. That figure is a 20-year high, surpassing even the previous record set during the 2013 Farm Bill reauthorization cycle, which had previously represented the sector's peak influence effort. In the five-year window from 2018 through 2022, total agribusiness lobbying reached $523 million, per the Union of Concerned Scientists and OpenSecrets. In the 2023–2024 election cycle, agribusiness contributed an additional $211,121,494 in documented campaign funds, according to OpenSecrets' industry contribution database (opensecrets.org/industries/contrib?ind=A). This is the money. The question this investigation pursues is what it purchased.
The policy context is not abstract. Equipment sales are projected to fall 15 to 20 percent in 2025, according to reporting by Legis1 dated November 4, 2025. The cause is a compounding squeeze: record-low crop prices suppress farmers' ability to buy equipment, while tariffs — specifically Section 232 levies on steel and aluminum and Section 301 tariffs on China-origin goods — have raised the cost of agricultural equipment by 13 to 16 percent. On a $500,000 combine harvester, that cost increase translates to $65,000 to $80,000 per unit. For a dealer network moving thousands of units annually, the aggregate competitive damage runs into the tens of millions of dollars. A tariff exemption, even probabilistically discounted, represents an economic prize whose expected value far exceeds the cost of lobbying and contributions required to pursue it. That is the rent-seeking calculus the American Enterprise Institute's analysis of farm-sector lobbying (2003–2020) describes as 'obtaining policies that benefit a well-defined, often small interest group at the expense of the rest of society.'
Into this environment, a new actor entered the federal lobbying space. Brandt Holdings Co. — a major John Deere dealership network with North American operations — retained Shumaker Advisors LLC as its federal lobbying firm, with the engagement reported by Legis1 on November 4, 2025. The registered issue areas are agriculture, manufacturing, and tax. Legis1 characterized Brandt's entry into federal lobbying as a signal that 'the farming industry is in crisis.' Brandt's move is significant precisely because it is a downstream dealer, not a manufacturer. When dealers — whose margins are compressed between fixed manufacturer pricing and farmers with diminished purchasing power — begin paying for Washington access, the pressure on the system has reached every level of the supply chain. The financial terms of the Brandt-Shumaker contract are not yet publicly disclosed; they will appear in the next quarterly LD-2 filing at lda.senate.gov under registrant Shumaker Advisors LLC.
The dominant equipment manufacturers — Deere and Company, CNH Industrial (which owns Case IH and New Holland), AGCO Corporation, and Kubota's U.S. subsidiary — are the largest market actors whose lobbying registrations would be expected to appear across LD-2 filings and whose contribution patterns would appear in OpenSecrets' database. This investigation reviewed the available sourced intelligence and found that specific contribution totals and lobbying expenditures for those companies in the current policy cycle are not captured in the compiled records. That gap is material. The Association of Equipment Manufacturers, the primary trade group for the equipment industry, similarly has LD-2 filings on tariff-related issues that are public record but were not reproduced in the source materials. Trade associations function as aggregators of political influence, allowing individual firms to pool lobbying resources behind industry-wide positions — such as tariff exemptions — that individual companies might be reluctant to seek under their own names.
The Cato Institute's analysis was conducted on data from the 2017–2021 administration, with the authors noting at publication that Biden-era exemption data was only beginning to become available. The current administration's exemption decisions — covering the 2025 tariff environment that has produced the 13 to 16 percent equipment cost increases — have not yet been subject to equivalent peer-reviewed analysis. That means the documented pattern of political favoritism in the exemption process is established as structural, but whether it is operative in the current cycle cannot yet be confirmed from the published record. What the record does confirm is that agribusiness has invested at historic levels in the political relationships the Cato study identifies as predictive of exemption outcomes.
What remains hidden is substantial. The specific lobbying expenditures of individual equipment manufacturers on tariff-related issues in 2024 and 2025 are traceable through LD-2 filings at lda.senate.gov but have not been compiled and cross-referenced against exemption application outcomes. The contribution profiles of equipment-sector companies versus commodity crop groups — who share the agribusiness OpenSecrets category — have not been disaggregated. Personnel records for Shumaker Advisors LLC have not been reviewed for revolving-door connections to USDA, the Office of the United States Trade Representative, or Congressional agriculture committee staff. And the U.S. International Trade Commission's Harmonized Tariff Schedule filings for HTS Chapter 84 (agricultural machinery) and Chapter 87 (vehicles) have not been cross-referenced against pending exemption applications to quantify exactly which products, at which rates, are the target of the current lobbying effort. The instrument that would reveal all of this is already public law: the Lobbying Disclosure Act requires quarterly LD-2 filings, the Federal Election Campaign Act requires contribution disclosure, and USITC tariff schedules are open records. The data exists. It has not yet been assembled in one place.
