Your Authorized Stepp Mfg Dealer
Brown Equipment Company is an authorized dealer for the complete line of Stepp Manufacturing asphalt hot boxes, pothole patchers, recyclers, and tack distributors. Since 1942, Stepp has been the standard for keeping asphalt at the perfect working temperature for efficient pothole repair.
Stop re-patching the same pothole every spring. Place hot mix that bonds and stays
Stepp Manufacturing has built hot boxes, hot patchers, tack coat distributors, and crack-sealing equipment out of North Branch, Minnesota since 1942. Eighty-plus years of engineering for the cold-climate duty cycle that defines Midwest, Great Lakes, and Northeast asphalt work: long winters, freeze-thaw potholes, short patching seasons, and crews that need to place hot material at the right temperature without burning it or letting it cold-spot.
The lineup spans four families. Hot boxes (SPHD, SPHD-3, SPHD-4) keep hot mix at working temperature for up to 48 hours with indirect-heat circulation, no burning, no cold spots, and consistent material across the box. Hot patchers integrate the hot box with truck-mounted dump capability so one chassis handles the full patching workflow from depot pickup through curbside placement. Tack coat distributors apply emulsified asphalt with heated spray bars for the bond-coat layer that keeps the patch in place across freeze-thaw cycles. Crack-sealing equipment fills the linear cracks that turn into potholes if they sit a winter, with melter geometry tuned for the rubberized sealant materials Midwest specs use.
Brown Equipment Company is the authorized Stepp dealer for the Midwest. We sell new units, stock the wear parts (burner nozzles, insulation panels, agitator components, distributor pump seals), and run factory-trained service across our seven Midwest locations. When a hot box loses heat in the middle of a patching shift, the same shop that delivered it handles the repair. Most stocked items ship same-day upon request from our Indianapolis distribution center.

Every Stepp Mfg model we sell
Browse the complete lineup, including inspection, components, and software solutions.
SPHD-4.0
4-ton dump-style pothole patcher with oil-jacketed heating. Keeps asphalt at working temperature for up to 48 hours and dumps material directly into the pothole.
SPHD-3.0
3-ton dump-style pothole patcher. Same oil-jacketed heating as the SPHD-4.0 in a mid-size package for crews that need dump-and-patch capability without full-size capacity.
SPH-4 Hot Box
4-ton asphalt hot box for crews that already have dump capability but need to keep material at working temperature all day. Oil-jacketed heating prevents degradation.
SPH-2 Hot Box
2-ton asphalt hot box in a compact tow-behind configuration. Load it at the plant in the morning and patch until it's gone, material stays workable all day.
SFB-2 Asphalt Recycler
2-ton asphalt recycler that heats and reconstitutes millings and reclaimed asphalt into usable patching material on-site. Saves material costs and landfill fees.
Tack Coat Distributor
Tack coat distributor for applying asphalt emulsion before overlay and patching operations. Ensures proper bonding between pavement layers.

Stepp Mfg: Common Buyer Questions
Answers to the questions municipal fleets and contractors ask most often before specifying Stepp Mfg equipment.
- Why does hot patching last longer than cold patching?
- Hot mix bonds to the existing pavement during compaction because the material is at working temperature when placed. The fresh asphalt fuses with the surrounding pavement edges and cures into a permanent patch. Cold patch is essentially loose aggregate held together with a weatherproofing binder. It fills the hole but doesn't bond to the surrounding pavement, so freeze-thaw cycles pop it back out within weeks. For permanent repairs, hot patching is the only durable option. Cold patch has its place as a temporary fix until hot weather, but it isn't a substitute for hot placement on lasting work.
- What is an indirect-heat hot box?
- An indirect-heat hot box circulates heated air or oil around the asphalt chamber rather than applying flame directly to the material. The result is consistent material temperature without burning, smoking, or cold-spotting. Direct-flame hot boxes overheat the material near the burner and cool it at the far end of the box, and the burned material loses its binder performance. Indirect heating is the standard for any crew that needs uniform hot mix across a long shift.
- What is an SPHD hot patcher?
- An SPHD is Stepp's combination unit that integrates an indirect-heat hot box with truck-mounted dump capability on a single chassis. The crew loads hot mix at the plant or the depot, drives to the patching site, keeps the material at temperature for the full shift, and dumps directly into the patch as needed. One chassis handles the full workflow instead of coordinating a separate hot box trailer with a dump truck.
- What is a tack coat and why does it matter for permanent patching?
- A tack coat is a thin layer of heated emulsified asphalt sprayed onto the existing pavement edges before the patch material goes in. The tack coat is the bond layer that fuses the patch to the existing road across freeze-thaw cycles. Without a tack coat, the patch sits as a discrete plug in the hole and pops out the first hard winter. Stepp tack coat distributors apply the heated emulsion uniformly so the bond layer is consistent across the patch edge.
- What materials do Stepp crack sealers work with?
- Rubberized asphalt sealants (the typical Midwest spec for centerline and longitudinal cracks), polymer-modified sealants, and standard emulsified asphalts. The melter geometry is tuned so the material reaches application temperature without overheating, and the application wand delivers consistent flow at the crack. Specific materials vary by state DOT spec; BEC can scope the right melter and application configuration to your typical crack-sealing program.
