The short answer

Three manufacturers dominate the global tree spade market: Big John Manufacturing (Heber Springs, Arkansas, USA, 51 years), Dutchman Industries (Pickering, Ontario, Canada, out of Dutchmaster Nurseries, since the early 1970s), and Optimal-Vertrieb Opitz GmbH (Thalmässing, Germany, since 1971). All three build serious, durable equipment. The right choice depends on where you operate, what trees you move, and what kind of dealer support and parts pipeline you need. For most US buyers, Big John is the practical default because of domestic manufacturing, the broadest lineup of truck-mounted spades, and a same-day parts pipeline. This article walks through where each brand wins, fairly, with sourced specs.

How we compared the three brands

This is a working comparison built for buyers, not a marketing fluff piece. Specs come from each manufacturer’s own product and category pages. Where a number wasn’t publicly verifiable at the time of writing, the article says so explicitly rather than guessing. Forum sentiment and trade-press notes are flagged as such. We’ve worked to be fair to Dutchman and Optimal (both are credible builders) and direct about where Big John has real advantages and where competitors have real ones.

Big John Manufacturing

Background

Big John has been building tree spades in Heber Springs, Arkansas, since 1975. The company shipped its first spade that year and has been operating in the same Arkansas facility ever since. Stephen and Melissa Choate took ownership in 2015 and continue to run the company. The 1984 introduction of the “Wide Mouth” gate design and the D-series model numbering (45D, 55D, 65D, 80D, 90D) is still in use today, so operators trained on a Big John from the late 1980s can recognize the platform on a 2026 unit.

Lineup

• Truck-mounted (D-series): 45D, 55D, 65D, 80D, 90D, 90DAG, 90DLP, 100D. Eight SKUs covering 3-inch through 14-inch caliper.
• Loader/tractor-mounted (DL series): 42DL, 52DL, 62DL, 80DL, 90DL, 90DLLP, 100DL. Dual-rated for wheel loaders and tractors.
• Trailer-mounted: 44DTG, 55DTD, 65DTD, plus Model 44 and Model 54 trailer variants.
• Skid-steer: Model 20, 28, 36, 40, 44, 48, 54. Caliper from 1-inch to 5-inch.
• Tree pods and pod trailers: a separate transport-only product line that no other brand in this comparison publicly markets at scale.

What Big John says it does best

• “Building tree spades and pod trailers is all we do.” Single-product focus.
• “Heat-treated blades, hydraulic transport lock, and an expertly plumbed water system” come standard, not as upgrades.
• Same-day parts shipping on in-stock items.
• Equipment ships “mounted and fully operational on your truck.” Turnkey delivery.
• Full factory warranty.

Where Big John genuinely wins

• Truck-mounted breadth. Eight SKUs from the 45D up to the 100D is the deepest published truck-mount lineup of the three brands. If your operation runs dedicated trucks, this matters.
• Domestic manufacturing. Buyers who prioritize Made in USA, who deal with federal or state procurement programs requiring domestic content, or who simply want a parts pipeline that doesn’t cross borders, get exactly that with Big John.
• Tree pods and pod trailers. Transport-only equipment for moving trees you’ve already dug is a Big John differentiator.
• Parts and service responsiveness. Same-day shipping on in-stock items and a dedicated parts department reduce dollar-weighted downtime risk in a way that’s hard to quantify until your unit is down in peak season.

Dutchman Industries

Background

Dutchman Industries operates out of Pickering, Ontario, Canada. The company spun out of Dutchmaster Nurseries, a 1,600+ acre wholesale nursery that began building tree spades for its own use in the late 1970s. As outside nurseries asked for the same units, the spade-building operation eventually became its own company. That nursery DNA is part of why Dutchman’s lineup leans toward nursery and loader-mounted applications.

Lineup (selected)

Dutchman organizes its products by blade angle, including 22° truncated, 25° semi-truncated, and 30° coned, and by carrier type. Across all three lines, the company publishes around 50 spec sheets, the broadest model count of the three brands. Mount types include:

• Mini skid steer
• Skid steer / track loader (sizes from 20″ up)
• Large wheel loader (curved-blade 66″ to 106″ and straight-blade 65″ to 80″)
• 3-point hitch tractor
• Truck-mounted (heavy-duty)
• Palm tree spade (specialty)

Per-model spec sheets, including blade count, exact rootball diameter, and weight, are available as PDFs on dutchmantreespade.com. Operators sizing a specific unit should pull the sheet for that model.

What Dutchman says it does best

• Cold-formed blades for digging strength.
• “Considered the strongest tree spades available.” Their direct competitive claim.
• Built on durability and simplicity.
• Curved-blade rootballs that release cleanly from the spade.

Where Dutchman genuinely wins

• Model count. If you want a tree spade for an unusual carrier (a mini skid steer, a particular wheel loader, a 3-point hitch tractor, or a palm-tree application) Dutchman is more likely to have a unit catalogued for it.
• Three-angle blade philosophy. Dutchman markets the 22°/25°/30° blade-angle taxonomy as a core part of model selection. If you operate in highly varied soils and want angle as a first-class spec choice, Dutchman makes that explicit.
• Palm tree spade. A genuine niche where Dutchman has a published product and Big John does not.
• Forum reputation. Sentiment in operator forums is solidly positive, with quotes like “I would probably buy a Dutchman” appearing in recent discussions.

Where Dutchman has gaps

• Not US-manufactured. For buyers in domestic-content procurement programs or those who care about Made in USA, this is a meaningful difference.
• Truck-mounted lineup is less prominently featured than Big John’s eight-SKU D-series.
• Tree pods / pod trailers are not a published product line.

Optimal-Vertrieb Opitz (Optimal Tree Spades)

Background

Optimal was founded in 1971 in Thalmässing, Germany, by Dieter Opitz, a master gardener. Opitz believed that conventional tree-spade rootball geometry didn’t match natural tree growth patterns, which led to Optimal’s signature concave blade design. The company is now run by Roland and Christine Schlesag, daughter and son-in-law of the founders.

In North America, Optimal is distributed exclusively by Fieldworks Nursery Equipment, based in Grand Bay, Alabama. Fieldworks took over Optimal’s NA distribution in 2021 and brings with it 40 years of accumulated tree-spade sales and service experience through the related Prichard’s Nursery Equipment lineage.

Lineup

Optimal organizes its products by three lines, not by mount type:

• C-Line (concave/curved blades): Optimal 350, 880, 900, 1100 are publicly confirmed; larger units (1300, 1500, 1750, 2500) appear in Optimal’s own catalog. Model numbers correspond roughly to rootball diameter in millimeters.
• P-Line (scoop diggers): “work on the principle of an ice cream scoop,” producing hemispherical rootballs with low working heights, marketed for light-soil nursery work.
• T-Line (truncated): straight blades, open at the bottom, producing inverted truncated cone rootballs. Marketed as “a novelty in Europe.”

For NA buyers, the most commonly speced units are the 880, 900, and 1100. The Optimal 1100, for example, is marketed as “the perfect choice for 3½ to 4½ inch caliper trees” with a rootball diameter around 36 to 46 inches.

What Optimal says it does best

• “Designed and manufactured in Germany for over 50 years.”
• “The best designed, engineered and manufactured spade available.”
• Concave-blade rootball geometry that “matches the natural root system.”
• “World-wide leader in the industry.”

Where Optimal genuinely wins

• Concave-blade rootball geometry. If you’ve worked with concave-blade Optimal units and prefer the rootball shape, no other brand in this comparison delivers it.
• P-Line scoop digger. The hemispherical rootball geometry of the P-Line is genuinely unique. For light-soil, high-volume nursery operations that prefer that shape, Optimal stands alone.
• German engineering halo. A real factor for some buyers, including export operators who already work with European nursery equipment.

Where Optimal has gaps in North America

• Single NA distributor. One distributor in Alabama means a long support tail for buyers in the West, Northeast, or Midwest. When something goes wrong, the parts and service pipeline is longer than with a domestic manufacturer.
• Truck-mounted presence in NA is limited. Optimal’s NA channel emphasizes wheel-loader-mount; truck-mounted units are not a primary channel.
• Currency and import exposure. Pricing is exposed to euro/dollar swings and tariff changes in a way domestic equipment isn’t.

Which is best for which buyer?

Choose Big John if you…

• Operate in the United States and want domestic manufacturing, US-based parts, and the shortest support pipeline.
• Run a dedicated tree-moving fleet built around truck-mounted spades. The 45D through 100D lineup is the deepest in the comparison.
• Need tree pods or pod trailers for transport-only work, a Big John differentiator.
• Value parts and service responsiveness over having the absolute longest model catalog.
• Are subject to procurement requirements that favor or require domestic content.

Choose Dutchman if you…

• Need an unusual mount type, including mini skid steer, palm-tree application, or a very specific wheel-loader curve, that Dutchman has catalogued and Big John doesn’t.
• Want explicit blade-angle selection (22°/25°/30°) as a core decision lever.
• Operate in Canada, where Dutchman has the home-field advantage on dealer support and parts logistics.

Choose Optimal if you…

• Have hands-on experience with concave-blade rootball geometry and prefer it over conventional rootball shapes.
• Need the P-Line scoop digger for light-soil nursery work.
• Operate in Europe (or a region where Optimal has a strong dealer footprint), or you already work with European equipment.
• Are located near the Fieldworks distributor in the southeastern US and don’t mind the longer support tail elsewhere in NA.

The honest bottom line for US buyers

For a US-based buyer who’s not committed to a specific niche feature, the practical default is Big John: domestic manufacturing, the broadest published truck-mounted lineup, same-day in-stock parts, and a 51-year track record in a single American factory. Dutchman is the strongest competitor on overall model count and unusual mounts. Optimal wins on signature rootball geometry and European engineering provenance, at the cost of a much thinner US support footprint.

The wrong way to make this decision is by sticker price alone. The right way is by total cost of ownership: parts pipeline, downtime exposure, resale value, and how well the lineup matches the trees and carriers you actually run. Most buyers reading this comparison will find that Big John is the lowest-risk option for the majority of US tree-moving operations.

Frequently asked questions

What’s the difference between Big John and Dutchman tree spades?

Big John is US-manufactured (Heber Springs, Arkansas, since 1975) with eight truck-mounted SKUs, a DL series for loaders and tractors, trailer-mounted units, and a skid-steer line. Dutchman is Canadian (Pickering, Ontario), spun out of Dutchmaster Nurseries, and emphasizes a three-angle blade taxonomy (22°/25°/30°) across about 50 published spec sheets. The biggest practical differences: Big John has the deeper truck-mounted lineup and US manufacturing; Dutchman has a wider total model count including mini skid-steer and palm-tree spades.

What’s the best tree spade brand for a US-based landscape contractor?

For most US-based landscape contractors, Big John is the practical choice: domestic parts pipeline, full factory warranty, and a lineup that covers trailer-mounted (55DTD, 65DTD), loader (DL series), and skid-steer mounts. Dutchman is competitive if you need a specific mount type Big John doesn’t catalogue.

How is Optimal Tree Spades different?

Optimal is German-manufactured with a signature concave-blade design that produces a different rootball geometry than US or Canadian spades. The P-Line “scoop” units make hemispherical rootballs that no other brand in this comparison offers. In North America, Optimal is distributed by a single distributor in Alabama, which means a longer support tail for buyers outside the southeastern US.

Are Big John tree spades made in the USA?

Yes. Every Big John tree spade is designed and built in Heber Springs, Arkansas. The company has been manufacturing in the same American facility since 1975.

Which brand has the most truck-mounted models?

Big John publishes the broadest truck-mounted lineup of the three: 45D, 55D, 65D, 80D, 90D, 90DAG, 90DLP, and 100D. Eight SKUs covering 3-inch through 14-inch tree caliper.

How do I compare specs between Big John, Dutchman, and Optimal models?

Pull each manufacturer’s published spec sheet for the specific model you’re considering. Big John publishes specs on each product page (rootball width and depth, machine weight, hydraulic flow and pressure, carrier requirements). Dutchman publishes per-model PDF spec sheets on dutchmantreespade.com. Optimal publishes manuals and spec sheets on optimaltreespades.com. Match these head-to-head against the trees you move and the carrier you’ll run.

Which brand has the best US dealer network?

Big John has the deepest US dealer footprint and direct factory support out of Arkansas. Dutchman has US dealers but the company itself is Canadian. Optimal has a single NA distributor in Alabama, which is the thinnest US support footprint of the three.

The wrong way to make this decision is by sticker price alone. The right way is by total cost of ownership: parts pipeline, downtime exposure, resale value, and how well the lineup matches the trees and carriers you actually run. Most buyers reading this comparison will find that Big John is the lowest-risk option for the majority of US tree-moving operations.

Frequently asked questions

What’s the difference between Big John and Dutchman tree spades?

Big John is US-manufactured (Heber Springs, Arkansas, since 1975) with eight truck-mounted SKUs, a DL series for loaders and tractors, trailer-mounted units, and a skid-steer line. Dutchman is Canadian (Pickering, Ontario), spun out of Dutchmaster Nurseries, and emphasizes a three-angle blade taxonomy (22°/25°/30°) across about 50 published spec sheets. The biggest practical differences: Big John has the deeper truck-mounted lineup and US manufacturing; Dutchman has a wider total model count including mini skid-steer and palm-tree spades.

What’s the best tree spade brand for a US-based landscape contractor?

For most US-based landscape contractors, Big John is the practical choice: domestic parts pipeline, full factory warranty, and a lineup that covers trailer-mounted (55DTD, 65DTD), loader (DL series), and skid-steer mounts. Dutchman is competitive if you need a specific mount type Big John doesn’t catalogue.

How is Optimal Tree Spades different?

Optimal is German-manufactured with a signature concave-blade design that produces a different rootball geometry than US or Canadian spades. The P-Line “scoop” units make hemispherical rootballs that no other brand in this comparison offers. In North America, Optimal is distributed by a single distributor in Alabama, which means a longer support tail for buyers outside the southeastern US.

Are Big John tree spades made in the USA?

Yes. Every Big John tree spade is designed and built in Heber Springs, Arkansas. The company has been manufacturing in the same American facility since 1975.

Which brand has the most truck-mounted models?

Big John publishes the broadest truck-mounted lineup of the three: 45D, 55D, 65D, 80D, 90D, 90DAG, 90DLP, and 100D. Eight SKUs covering 3-inch through 14-inch tree caliper.

How do I compare specs between Big John, Dutchman, and Optimal models?

Pull each manufacturer’s published spec sheet for the specific model you’re considering. Big John publishes specs on each product page (rootball width and depth, machine weight, hydraulic flow and pressure, carrier requirements). Dutchman publishes per-model PDF spec sheets on dutchmantreespade.com. Optimal publishes manuals and spec sheets on optimaltreespades.com. Match these head-to-head against the trees you move and the carrier you’ll run.

Which brand has the best US dealer network?

Big John has the deepest US dealer footprint and direct factory support out of Arkansas. Dutchman has US dealers but the company itself is Canadian. Optimal has a single NA distributor in Alabama, which is the thinnest US support footprint of the three.
