Allis-Chalmers Model 116: Best for the Model G

The Model 116 is uniquely designed to mount directly to the rear of the Allis-Chalmers Model G. Because the G is rear-engine, this plow is engineered to offer exceptional visibility, allowing for precision work in confined garden rows. It turns over a narrow but clean furrow that prevents the soil from compacting excessively.

This plow is the undisputed champion for the G owner who prioritizes accuracy over raw speed. If the garden features long, narrow runs or requires working close to permanent fence lines, this unit is indispensable. It avoids the “drift” often seen with tow-behind implements.

The Model 116 is not intended for heavy, virgin sod breaking. It excels in established garden soil that has been previously worked. For the serious vegetable gardener, this is the definitive choice for maintaining consistent row depth and soil aeration.

Allis-Chalmers No. 62 Snap-Coupler: Top Two-Bottom

The No. 62 Snap-Coupler plow is the gold standard for versatility when working with D-series tractors or any AC machine equipped with the Snap-Coupler hitch system. The “Snap-Coupler” design allows for incredibly fast attachment and detachment, which is vital when switching between plowing and cultivating in a single afternoon.

Two-bottom plows provide the ideal width for small to mid-sized hobby plots, balancing the weight against the tractor’s traction. A two-bottom setup is often more stable than a single-bottom, as it keeps the tractor centered and level while traveling down the furrow. It allows for a more efficient turnover of the earth, covering more ground without needing to shift gears constantly.

Operators should choose the No. 62 when time is the limiting factor in the farm plan. It represents the perfect equilibrium between the light touch required for a home garden and the power output of a standard vintage AC tractor. It is a robust, reliable workhorse that will handle moderate cover crops with ease.

Allis-Chalmers No. 81 Snap-Coupler: Best Single-Bottom

For those working with smaller plots or tighter turnarounds, the No. 81 Snap-Coupler single-bottom plow is a masterclass in simplicity. Single-bottom plows reduce the “side draft” on the tractor, making it easier to steer and manage in spaces where maneuverability is at a premium.

The No. 81 is ideal for the farmer who values precision over volume. Because it only has one moldboard, it places significantly less strain on the tractor’s hitch and hydraulic lift system. This extends the longevity of the tractor’s components, which is a major factor for those maintaining older equipment.

Consider this plow if the garden layout includes frequent obstacles like fruit trees or raised beds. Its compact footprint allows for navigating tricky corners that would cause larger multi-bottom plows to strike nearby vegetation. It is the preferred choice for finesse, not force.

Allis-Chalmers No. 1 Plow: For The B, C, and CA

The No. 1 plow is the classic companion for the B, C, and CA series tractors. These tractors are arguably the most popular platforms for hobby farmers, and the No. 1 plow matches their power band perfectly. It is a balanced, lightweight implement that doesn’t overwhelm the tractor’s front end, preventing the front wheels from lifting during challenging pulls.

When utilizing a B or C model, matching the plow weight is crucial for safety and steering control. The No. 1 is designed to track straight, reducing the need for constant steering corrections. It is a straightforward, no-nonsense tool that turns soil effectively without requiring an advanced degree in hydraulics.

For farmers operating in lighter, loam-based soils, this plow is sufficient for primary tillage. It represents a period of engineering where equipment was built to be repaired in the field with basic tools. It remains a top choice for those who value mechanical simplicity and long-term durability.

Allis-Chalmers Disc Plow: Handles Tough, Sticky Soil

Standard moldboard plows often struggle in clay-heavy or exceptionally sticky soil, as the earth tends to cling to the steel surface. The Allis-Chalmers disc plow solves this by using rotating discs to slice through the ground, forcing the soil to invert and crumble. It is the “nuclear option” for difficult terrain.

This implement is the right selection when the soil moisture is unpredictable. If the plot tends to stay wet or contains high concentrations of heavy clay, a moldboard plow will “gum up,” leading to frustration and poor tillage results. The disc plow maintains its performance by shedding soil through centrifugal force as the blades rotate.

While it requires slightly more adjustment to get a uniform furrow, the trade-off is superior performance in less-than-ideal conditions. It is the specialized tool for the farmer working against the elements. If the plot feels like concrete in August or a swamp in April, the disc plow is the only answer.

Allis-Chalmers Subsoiler: Perfect for Hardpan Busting

Deep tillage is often overlooked, but the Allis-Chalmers subsoiler is essential for long-term soil health. It is designed to penetrate well below the layer reached by a regular plow, breaking up the “hardpan”—a compacted layer of soil that prevents root development and water drainage.

Use this tool once every few years as a corrective measure for compacted garden beds. It does not turn the soil like a moldboard plow, but instead shatters it, allowing air and water to penetrate deep into the subsoil. This is vital for deep-rooted crops like carrots, parsnips, or potatoes.

A subsoiler is not for routine annual preparation, but for structural soil improvement. It requires significant traction, so ensure the tractor has the weight to pull it effectively. For the hobby farmer looking for high-quality, long-term soil architecture, this is the most important implement to keep in the shed.

Allis-Chalmers One-Bottom Trip Plow: Simple & Reliable

The One-Bottom Trip Plow is a favorite for those working in rocky or stump-filled ground. It features a “trip” mechanism that allows the plow to swing upward if it strikes an obstruction, preventing damage to the plow frame or the tractor’s hitch. It essentially saves the operator from the common catastrophe of hitting a hidden rock at full speed.

Reliability is the hallmark of this design. The mechanical trip is robust and rarely fails, providing peace of mind when working on older, unimproved land. It is the ideal plow for the beginner or for anyone working ground that hasn’t been thoroughly cleared of debris.

This is a “set it and forget it” tool that prioritizes durability above all else. While it may not offer the precision of more modern implements, it offers the ultimate insurance policy for the tractor. If the soil contains hidden obstacles, do not choose anything else.

Matching Your Plow to Your AC Tractor’s Power

The success of any plowing endeavor rests on the horsepower-to-tillage ratio. Overloading a smaller tractor like a Model G with a multi-bottom plow leads to excessive clutch wear and engine strain. Conversely, using a single-bottom plow on a larger D-17 is a waste of fuel and efficiency.

Consult the manufacturer’s original specifications for the “drawbar horsepower” of the tractor. As a general rule, provide at least 10 to 12 horsepower per bottom for moldboard plowing. If the soil is heavy clay, increase that margin to ensure the engine doesn’t lug down or overheat.

Always account for tire traction and ballasting. Even the most powerful tractor is useless if the rear wheels spin in place. Add liquid ballast or suitcase weights to the rear to ensure the plow can reach its intended depth without the tractor sliding sideways in the furrow.

How to Set Your Plow for a Perfect Furrow

The “perfect furrow” is a product of proper hitch and coulter adjustments. Start by ensuring the tractor is positioned squarely with the rear tire running snugly against the furrow wall. The plow should be leveled side-to-side using the leveling crank on the lift arm to ensure the shares engage the soil at the same angle across the width of the cut.

The coulter—the circular blade in front of the share—must be set to cut cleanly through the sod or cover crop before the share turns the soil. A dull or improperly set coulter results in a ragged, uneven turnover. Set the depth of the coulter to be slightly shallower than the plow share itself for the best results.

Finally, adjust the “landside” pressure to prevent the plow from pulling toward the unplowed ground. The plow should track true behind the tractor with minimal steering input. If the tractor is constantly fighting to stay straight, adjust the horizontal angle of the plow attachment point until the pull feels neutral and balanced.

Maintaining Your Vintage Plow for Years of Service

Plow maintenance is largely focused on protecting the steel from rust and ensuring the moving parts remain lubricated. After every season, clean the moldboards and shares thoroughly, then apply a light coating of oil or specialized plow grease. Exposed, rusted steel creates friction, forcing the tractor to work harder and creating a poor finish.

Sharpen the shares periodically using a heavy-duty grinder, maintaining the original bevel angle. A dull share significantly increases the drawbar pull required, draining fuel and stressing the hydraulic system. If a share is worn down to the point where the mounting bolts are exposed, replace it immediately to prevent damaging the frog of the plow.

Check all trip mechanisms and hinges for debris buildup or seized pivot points. A spray of penetrating oil applied to these areas before storage will ensure they function correctly when the spring thaw arrives. These simple habits transform a 70-year-old piece of equipment into a modern farming asset.

By selecting the right Allis-Chalmers plow for your specific soil and tractor, you turn labor into a manageable, productive task. Investing in the correct gear—and maintaining it with care—ensures that every row you turn is a step toward a more successful harvest.
