Designed and manufactured in Germany for over 50 years, Optimal is the world-wide leader in the industry with spades ranging in size from 14 – 98 inches. About Fieldworks Nursery Equipment Our Story Serving you since 2021. Fieldworks Nursery Equipment was built from the ground up — not from a sales office, but from a working nursery. For more than 30 years, Jason White and Palms Unlimited have been growing, digging, and transplanting trees and palms across the Gulf Coast. That hands-on experience shaped everything: an understanding of what professional growers need, what equipment holds up in the field, and what it takes to keep operations moving day after day. Through years of real-world use, Optimal Tree Spades became an essential part of that process — trusted for their durability, reliability, and performance when it matters most. Before Fieldworks, Optimal Tree Spades were represented in the United States by Phil and Pritchard’s Nursery Equipment, where Phil spent more than 15 years building relationships, supporting customers, and helping establish Optimal’s reputation in the industry. When it came time for the next chapter, Phil entrusted Jason and Fieldworks to carry that legacy forward. Together, they traveled to Germany to meet with the manufacturer and ensure a smooth transition — one built on the same values that have always mattered most: quality equipment, dependable parts, and honest, knowledgeable customer support. Today, Fieldworks continues that tradition with a perspective few others can offer: we don’t just sell tree spades — we use them ourselves. That means when you call us, you’re talking to people who understand the work because we do it too. We know the questions that come up, the problems that can happen, and the urgency behind getting answers quickly. We believe customer support should be personal. When growers and landscapers reach out, they deserve more than a sales pitch — they deserve real conversations, honest advice, and someone who genuinely cares about helping them find what they need. Whether it’s choosing the right machine, troubleshooting in the field, or finding the right parts, we’re here to help because we understand how important your equipment is to your business. Every machine we represent is backed by decades of nursery experience, field-tested knowledge, and a commitment to serving our customers the same way we’d want to be served ourselves. Our mission is simple: honor the foundation built before us, support the people who keep this industry moving, and equip the next generation with tools they can trust.
