What Shivvers Manufacturing does

Shivvers Manufacturing is a family-owned agricultural machinery manufacturer founded in 1968 in Corydon, Iowa, by brothers Charles and Gerald Shivvers, now led by Carl Shivvers as President. The company designs and builds grain drying systems based on a proprietary Counter-Flow drying architecture that processes grain at 36–96 inch depths (versus the conventional 12–18 inches), supported by the foundational patented tapered sweep auger, Blue Flame burner technology, computerized Command Centers (Premier, CompuDry TS, CompuDry), and an IoT-style remote management platform (Link, STIG Auto-Bin). Its core product families are the Circu-Lator Performance Systems (continuous-flow and batch drying with recirculation), Dri-Flo Performance Systems (for operators with existing transfer systems up to 2,500 bph), and Hemp Drying Systems, with system capacities ranging from 6,000 to 52,800 bushels per day. The company operates from a 120,000 sq ft manufacturing, office, and warehouse facility on a 20-acre site with approximately 150 associates, and holds US Patent 11,796,251 B2 for hemp biomass drying.

The company sells exclusively through an authorized US dealer network—no direct-to-consumer or online parts sales—with five regional sales representatives (Western/North Central, Central, South Central, South East, Northeastern districts) supporting dealers and end customers. Pricing is opaque and set at the dealer level; the company does not publish list prices. Target customer segments are row crop farmers (primary), hemp and cannabis biomass producers, specialty crop growers (sunflowers, popcorn, coffee, buckwheat, canola, milo, rye, barley, rice, flax), and brewery/distillery feedstock suppliers. Marketing is conducted primarily through 13+ major US farm shows, an extensive YouTube video library, customer testimonials, and dealer referral. The company also operates the wholly-owned Country Clipper zero-turn radius lawn mower division, launched in 1984 as a counter-cyclical hedge against agricultural volatility, and the wholly-owned Shivvers Technology & Innovation Group (STIG) subsidiary for digital monitoring products. Shivvers remains a private, family-controlled corporation with no external funding, M&A activity, or public financial disclosures.

Core offering

Shivvers Manufacturing designs, produces, and sells proprietary counter-flow grain drying systems (Circu-Lator, Dri-Flo, and Hemp Drying Systems) along with supporting components—computerized Command Centers, fan/heater combinations, transfer augers, drying floors and supports, grain loaders/spreaders, and accessories—plus remote grain bin monitoring solutions. Equipment is manufactured at its Corydon, Iowa facility and sold exclusively through an authorized U.S. dealer network with regional sales representatives, serving row crop, specialty crop, and hemp/biomass producers.

Product overview

Shivvers Manufacturing offers a comprehensive portfolio of grain drying systems and components built around proprietary Counter-Flow Drying Technology. The core product line includes three main drying system families: Circu-Lator Performance Systems (featuring center vertical auger for continuous-flow and batch drying with bin-to-storage recirculation), Dri-Flo Performance Systems (horizontal unload design for existing transfer systems up to 2,200 BPH), and Hemp Drying Systems (custom-configured biomass drying). Supporting these systems are six core components: Command Centers (Premier, CompuDry TS, CompuDry computerized controllers), Fan & Heater Combinations (Blue Flame technology in axial and centrifugal configurations), Transfer Augers (continuous-flow, horizontal, jumpster, and vertical unload), Floors & Supports (Channel-Lock Drying Floors), Grain Loading & Spreaders (Level-Dry, Controlled-Flow, Grain Hog), and Core Machines. Additional offerings include the Link Remote Management System for remote monitoring/control and Auto-Bin Grain Bin Monitoring System for stored grain oversight. The company designs and manufactures all equipment at its Corydon, Iowa facility with capacities ranging from 6,000 to 52,800 bushels per day.

Partnerships

One partnership is on record.

• Country Clipper (Sister Company)coreOthers · 1 January 1984In 1984, Shivvers diversified into non-agricultural products to help the company survive economic fluctuations. The company developed the Country Clipper line of zero-turn radius lawn mowers, which continues to be a thriving division of the Shivvers family business. This represents internal diversification rather than an external partnership.

Direct peers

• GSI (Grain Systems, Inc.): GSI is one of the largest US manufacturers of grain bins, dryers, and material handling equipment for on-farm and commercial grain operations. Directly comparable to Shivvers across grain drying systems and bin-integrated solutions.
• Sukup Manufacturing: Sukup is a major US family-owned manufacturer of grain dryers, bins, and material handling equipment based in Iowa. Competes head-to-head with Shivvers in the grain drying market, including counter-flow and mixed-flow dryer offerings.
• Brock Grain Systems: Brock manufactures grain storage bins, dryers, and conditioning equipment for agricultural operations. A direct competitor in the commercial and on-farm grain drying market, serving similar Midwest farmer and commercial elevator customers.
• Mathews Company (M-C): M-C is a US-based manufacturer of grain dryers (both portable and stationary), with a focus on continuous-flow and batch drying. Direct competitor in the agricultural grain dryer category.
• Neco: Neco manufactures grain dryers, aeration systems, and material handling equipment for on-farm and commercial applications. Directly comparable in the mixed-flow and continuous-flow grain drying space.

Broad incumbents

• AGCO Corporation: AGCO is a global agricultural equipment major whose GSI division competes with Shivvers in grain storage and drying. Operates across the full ag equipment spectrum (tractors, combines, hay tools) so grain drying is a sub-vertical rather than core focus.
• CTB Inc. (Berkshire Hathaway): CTB is a Berkshire Hathaway subsidiary that owns multiple ag equipment brands including Brock Grain Systems and grain handling/drying product lines. A broad incumbent with overlapping grain handling capabilities and substantial capital backing.
• Bühler Group (Aeroglide): Bühler's Aeroglide division produces industrial and food-grade drying and cooling equipment, including grain drying technology. A broad incumbent competing across commercial-scale grain processing rather than on-farm niche.

Emerging players

• Zimmerman Grain Dryers: Zimmerman is a smaller US manufacturer specializing in tower-style continuous-flow grain dryers. An emerging player with partial overlap in the continuous-flow grain dryer segment where Shivvers also competes.

Others

• KSi Conveyors: KSi manufactures seed handling, treatment, and conveying equipment adjacent to grain drying infrastructure. Indirectly comparable as an ecosystem participant whose equipment integrates with grain drying and storage systems.
