Understanding the Legacy of Van Brunt Drills

The Van Brunt Manufacturing Company originally built its reputation on precision and durability before being acquired by John Deere in the early 20th century. These drills became the gold standard for small-scale farmers and are now prized by DIY land managers.

Most homeowners today use the Model B or the Model FB, which are famous for their “fluted feed” mechanism. This design allows for a wide variety of seed sizes, from tiny clover to large beans, to pass through without damage.

Because these machines were built to last decades, many are still sitting in barns waiting for a second life. A few key replacements can turn a rusty relic into a high-precision planting tool for your property.

Essential John Deere Van Brunt Grain Drill Parts for Routine Maintenance

When you begin a restoration or a seasonal tune-up, you must focus on the parts that directly contact the soil or move the seed. These components experience the most friction and environmental stress over time.

The disc openers are perhaps the most critical part of the assembly. These circular blades cut the furrow where the seed will rest, and if they are dull or rusted, your planting depth will be inconsistent.

Next, inspect the seed tubes, which are often made of rubber or flexible steel ribbon. Over time, rubber tubes can dry rot and crack, leading to seed loss before it ever reaches the ground.

  • Scrapers: These metal plates keep the discs clean of mud and debris.
  • Pressure Springs: These provide the “down force” needed to penetrate hard soil.
  • Seed Cups: These hold the fluted rolls that meter out your seeds.
  • Bearings: Essential for the smooth rotation of the main drive shaft and the discs.

Replacing these john deere van brunt grain drill parts early prevents a total mechanical failure in the middle of your planting window. A well-maintained drill ensures that every seed you buy has the best possible chance to germinate.

Identifying Your Specific Model and Series

Before you order any components, you must identify whether you have a Model B, BB, FB, or the later B-A series. Look for the serial number plate, usually located on the rear frame or near the tongue of the drill.

The “FB” models often feature a fertilizer box in addition to the grain box, which requires additional maintenance for the auger system. Fertilizer is highly corrosive, so these parts often need more frequent replacement than standard grain components.

If the plate is missing, count the number of seed openers and measure the spacing between them. Common configurations include 7-inch or 8-inch spacing, which helps narrow down which parts will fit your specific frame.

The Importance of the Fluted Feed Roll

The fluted feed roll is the heart of the metering system. As the drive wheel turns, these rolls rotate to pull seed from the hopper and drop it into the tubes.

Check these for pitting or rust, which can catch seeds and cause “grinding.” If the flutes are worn down, your calibration will be off, and you may end up over-seeding or under-seeding your plot.

Replacing these rolls is a straightforward DIY task that involves sliding the square feed shaft out of the seed cups. Always apply a light coat of dry graphite lubricant to these parts rather than grease, as grease can attract dust and clog the mechanism.

Step-by-Step Restoration: Replacing Worn Seed Tubes and Discs

To begin your repair, park the drill on a flat, level surface and use heavy-duty jack stands to support the frame. Safety is paramount when working under heavy agricultural equipment.

Start by removing the old seed tubes. If they are the ribbon-steel type, check for kinks or rust holes; if they are rubber, look for any signs of brittleness or cracking at the attachment points.

When replacing the discs, you will likely need a large breaker bar and penetrating oil. The bolts holding the disc bearings are often seized from years of contact with damp soil and fertilizer.

  1. Spray all bolts with penetrating oil 24 hours before you plan to work.
  2. Remove the hubcap and the cotter pin holding the disc in place.
  3. Inspect the inner bearing race for signs of pitting or uneven wear.
  4. Install the new disc and tighten the nut until the disc spins freely without wobbling.
  5. Reattach the scrapers, ensuring they sit about 1/16th of an inch away from the disc surface.

By taking the time to source high-quality john deere van brunt grain drill parts, you ensure that the discs will stay sharp for several seasons. This allows for better soil-to-seed contact, which is the most important factor in successful germination.

Calibrating Your Drill for Modern Seed Varieties

Modern seeds are often treated with coatings or have different densities than the seeds used when these drills were first manufactured. You cannot always rely on the original acreage charts inside the lid.

To calibrate manually, jack up the drive wheel and place a tarp or several buckets under the seed openers. Turn the wheel a specific number of times to simulate 1/10th of an acre.

Collect the seed, weigh it, and multiply by ten. This gives you the actual seeding rate per acre. Adjust the feed gates on the back of the seed cups until you hit your target weight for your specific crop.

Ensure that all feed gates are set to the same notch. If one gate is wider than the others, your rows will be uneven, leading to patchy growth and increased weed competition in the thinner areas.

Managing Soil Health and Compaction

When using a grain drill, soil conditions matter just as much as the machinery. If your soil is too compacted, even new john deere van brunt grain drill parts won’t be able to penetrate to the correct depth.

Consider aerating the soil or using a light disk harrow before planting if the ground is hard-packed. This reduces the strain on your drill’s pressure springs and helps the seed tubes deposit the grain into a loose, nutrient-rich environment.

Properly adjusted down-pressure ensures that the seed is buried at the ideal depth—usually twice the diameter of the seed itself. For most grasses, this is about 1/4 to 1/2 inch deep.

Troubleshooting Common Planting Issues

If you notice “skips” in your field where nothing is growing, the first place to look is the seed cup assembly. Debris like straw or old seed hulls can clog the opening, preventing the fluted roll from grabbing new seeds.

If the drill is making a clicking or grinding noise, check the drive chains and sprockets. These chains often stretch over time and can jump teeth, which disrupts the timing of the seed delivery.

Check the tension of the drive chains regularly. You should have about half an inch of play in the longest span of the chain. Use a dedicated chain lube that dries to a waxy finish to avoid attracting dirt and grit.

  • Uneven depth: Check for broken pressure springs or bent opener arms.
  • Seed on the surface: Ensure the discs are sharp and the scrapers aren’t clogged with mud.
  • Wobbly wheels: Inspect the main axle bearings and tighten the lug nuts.

Keeping a small kit of spare john deere van brunt grain drill parts, like extra cotter pins and a few seed tube clamps, can save you a trip back to the shop during the busy planting season.

Safety First: Handling Vintage Machinery

Working on older equipment requires a “safety-first” mindset. Always wear heavy leather gloves when handling discs, as the edges can be surprisingly sharp even when worn.

If you are cleaning out an old fertilizer box, wear a dust mask and eye protection. Old fertilizer dust can be irritating to the lungs and skin, and it often contains concentrated minerals that shouldn’t be inhaled.

Never attempt to adjust the seed gates or chains while the tractor is running or the drill is in motion. Always disengage the power take-off (PTO) or the ground drive before performing any maintenance or clearing a clog.

Where to Buy Quality Replacement Parts

While your local John Deere dealer might still carry some basic items, many john deere van brunt grain drill parts are now classified as “vintage.” However, the aftermarket industry is robust.

Look for suppliers that specialize in “Planter and Drill Parts.” These companies often manufacture heavy-duty versions of the original components using modern alloys that resist rust better than the original 1950s steel.

Online forums and agricultural auctions are also excellent places to find “donor” machines. Sometimes buying a second, non-functional drill for a few hundred dollars is the cheapest way to acquire a full set of original gears and shafts.

FAQ: Common Questions About Van Brunt Drills

How Do I Know If My Seed Tubes Need Replacing?

Inspect the tubes for any light passing through cracks or holes. If you see seed spilling out of the sides of the tube rather than the bottom, or if the tube feels brittle and stiff, it is time for a replacement.

Can I Use a Van Brunt Drill for No-Till Planting?

Generally, no. These drills were designed for prepared seedbeds. While they have pressure springs, they usually lack the extreme weight and heavy-duty coulters required to cut through thick sod or heavy crop residue without prior tillage.

What Is the Best Way to Prevent Rust During the Off-Season?

The best method is to completely empty the seed and fertilizer boxes. Use a shop vac to remove every grain, then spray the interior and all moving parts with a thin layer of fluid film or light oil to create a moisture barrier.

Are the Parts for a Model B and Model FB Interchangeable?

Many parts, like the discs and seed tubes, are interchangeable. However, the drive mechanisms and the frame components often differ because the FB model includes the fertilizer drive system. Always verify the part number before purchasing.

Conclusion: Bringing New Life to Your Land

Restoring a vintage seeder is a rewarding project that connects you to the history of the land while providing a practical tool for your modern gardening or landscaping needs. By focusing on high-quality john deere van brunt grain drill parts, you ensure that your equipment remains a reliable partner in your outdoor projects.

Take the time to inspect your discs, lubricate your bearings, and calibrate your metering system before the first sign of spring. With a little patience and the right components, your Van Brunt drill will continue to lay the foundation for lush, healthy growth for years to come.
