The NEW Towmaster T-30D Delivers True 13,608 kg Payload Capacity

As underground utility work expands across the country, from urban fiber optic installations to remote oil and gas pipelines, contractors are demanding more from their trailers. The days of squeezing oversized drills, water tanks, and mixing systems onto tandem axle trailers are over. From Towmaster headquarters in Litchfield, Minnesota (USA) comes the new Towmaster T-30D, a triple-axle drop-deck trailer that redefines what’s possible when it comes to hauling heavy, wide, and fully outfitted directional drilling systems.

The Why Behind the T-30D

«We saw a growing need across the country for a trailer that could carry everything,» explains Mike Banken, Engineering Manager for Towmaster. «Many contractors want everything in one place drill, water tank, mixing system, extra rods, all of it. The only way to do that was with a third axle.» Everything about this trailer is designed with real-world durability in mind, from its cold-formed I-beam main frame, junior I-beam crossmembers to optional «stuff holders» and drill-ready customization packages.

Traditionally, contractors using tandem-axle trailers have faced limits when trying to load larger equipment like the Ditch Witch JT-20 or the Vermeer D-24x40 HDD drill. These machines weigh nearly 5443 kg before you even add 1893 litre of water, a mixing system, or drill rods. With that kind of load, it’s easy to exceed the capacity of most standard trailers, and many trucks aren’t set up to carry water tanks in the bed. That’s where the T-30D steps in.

Adjustable full-width ramp rods let you position ramps left or right, exactly where you need them, depending on the machine you’re hauling. This feature is standard on the T-30D, learned from Towmaster’s experience with drill trailers, where flexible ramp setups are crucial.

Engineered for the Equipment You Actually Haul

Towmaster built the T-30D trailer to solve a real problem: how to safely, legally, and efficiently move the full loadout of a modern underground utility setup. It’s not just about hauling the drill anymore; it’s about moving the entire drill system. The T-30D boasts a TRUE 13,608 kg payload capacity, making it the biggest in the business. Compare that to some competitor’s 12,247 kg maximum payload capacity and the Towmaster clearly comes out on top for hauling capability.

Custom Options for Drill-Ready Convenience

Towmaster understands that not every jobsite is the same. That’s why the T-30D can be customized to meet specific mounting specs for water tanks, rod holders, and mixing systems. Customers can even drive off the lot with a trailer that’s completely drill-ready, no welding, no mods, no wasted time.

Three 5443 kg spring axles deliver a 16,329 kg GAWR (Gross Axle Weight Rating) — perfect for hauling everything from directional drills to any heavy-duty equipment you need on the job.

In a market where utility contractors are pushing the limits of their equipment every day, the Towmaster T-30D steps up with the strength, versatility, and smart design needed to meet those demands. Whether you're hauling a full-size directional drill, a water tank, mixing system, or extra rods, this trailer is purpose-built to carry it all. As Bob Pace, Sales Manager for Towmaster’s Trailer Division explains, «With the T-30D, you can finally put all your equipment on one trailer. It’s built to handle the whole load—drill, tank, and mix system, without any compromises.»

Towmaster built the T-30D to meet the needs of utility contractors, municipalities, and telecom providers who are moving larger equipment more frequently. From fiber crews to public works departments, the demand for higher-capacity, full-featured trailers continues to grow. If you're hauling a heavy, wide, or fully outfitted directional drill system, you need more than just a trailer — you need the Towmaster T-30D. For crews done making trade-offs, the T-30D isn’t just a trailer, it’s the answer they’ve been waiting for.

Towmaster’s new T-30D trailer delivers a TRUE 13,608 kg payload capacity with a triple-axle design and full-width drop deck that extends in front of the fenders—perfect for wider directional drills and mini excavators that need more space and better balance.
