The subsoil mulching industry is still in its early stages, but a handful of manufacturers have already developed purpose-built attachments and machines capable of performing true below-grade mulching. As demand for this land clearing method grows worldwide, the number of manufacturers entering the space is expected to increase significantly. Below is a guide to the current known manufacturers producing subsoil mulching attachments and dedicated machines, along with key specs and what each product is best suited for.
Current Subsoil Mulching Manufacturers
Coneteks — USA
Website: coneteks.com
Coneteks is the first manufacturer to design and produce a subsoil mulching attachment built and supported entirely in the United States. Engineered for skid steer and track loader carriers, the Coneteks attachment is a true all-in-one land clearing solution that mulches, grinds, and buries debris below grade in a single pass.
Available Models (3 sizes: 76″ to 103″ working width)
| Spec | Smaller Units | Larger Units |
| Working Width | 76″ | 88″–103″ |
| Weight | 2,160 lbs | 2,420 lbs |
| Min. Hydraulic Flow | 28 GPM | 30 GPM |
| Recommended HP | 75 HP (minimum) | Higher HP required |
| Mulching Depth | Up to 6″ (universal rotor) | Up to 8″ (forestry rotor) |
| Warranty | 2 years | 2years |
Rotor Options:
- Universal Rotor — Fixed-tooth, non-replaceable blades. Best for brush, small trees, and general vegetation. Leaves a finer finish and can mulch up to 8″ below grade.
- Forestry Rotor — Replaceable teeth designed for heavy-duty mulching of thick vegetation and stumps. Built for durability in demanding forestry environments.
Best For: Contractors using skid steers or track loaders looking for a versatile, US-built attachment with strong dealer and parts support.
Production Rate: 1.5–2 acres per day from moderate brush to finished soil condition.
TMC Cancela / MulchTech — Spain (Global)

| Mulching Depth | Up to 350mm (13.7″) |
| Construction | Hardox® Steel with Carbide Hammers |
| Power Requirement | 280–400 HP |
| Working Width | 225–250 cm |
| Carrier Type | High-horsepower tractor |
MPK — Mulcher Sub-Soiler
| Spec | Details |
| Material Diameter | Up to 450mm (17.7″) |
| Power Requirement | 180–280 HP |
| Working Width | 225–250 cm |
| Carrier Type | Mid to high-horsepower tractor |
Best For: Large-scale agricultural and forestry operations requiring deep root and stump elimination across wide working widths. Ideal for farm reclamation and reforestation projects.
Seppi M. — Italy (Global)
Website: seppi.com
Founded in 1939, Seppi M. is one of the most established names in forestry and agricultural mulching equipment. Their MULTIFORST model functions as a combined forestry mulcher, stone crusher, and soil tiller — making it one of the most versatile subsoil-capable attachments on the market.
MULTIFORST
| Spec | Details |
| Nominal Power | 140–180 HP |
| Working Width | 200 cm (78″) |
| PTO Speeds | 1,000 RPM (mulching) / 540 RPM (stone crushing & soil tilling) |
| Carrier Type | PTO-driven tractor |
| Rotor | High-performance with tungsten carbide inserts |
Key Feature: Dual PTO speed allows operators to switch between surface mulching at 1,000 RPM and below-grade soil tilling and stone crushing at 540 RPM — giving it true subsoil capability alongside traditional mulching functions.
Seppi also produces the MiniSoil CL is a heavy-duty, hydraulically driven attachment designed for skid steer type tractors (SAE Standard). Despite its compact, low-profile design, it’s powerful enough to handle demanding land clearing, forestry mulching, brush removal, and deep soil conditioning, all in one operation.
| Specification | Details |
| Working Width | 59″ (150 cm) |
| Weight | 2,560 lbs (1,160 kg) |
| Hydraulic Flow Range | 28 – 66 GPM (105 – 250 L/min) |
| Working Depth | Up to 4″ below grade |
| Max Stone Diameter | Up to 6″ (15 cm) |
| Max Wood Diameter | Up to 8″ (20 cm) |
Of the four subsoil mulchers on the market, only the Coneteks is engineered and rated to handle standing trees and brush, giving them a distinct operational advantage.
A Growing Industry — More Manufacturers Coming
The machines listed above represent the current known manufacturers producing equipment with genuine subsoil mulching capability. However, this is a rapidly evolving space. As awareness of subsoil mulching grows globally and demand increases from contractors, farmers, and land managers, more manufacturers are expected to enter the market with new designs, improved specifications, and broader carrier compatibility.
What to Look for When Comparing Equipment
When evaluating subsoil mulching attachments or machines, consider the following:
- Carrier Compatibility — Does the attachment match your existing skid steer, track loader, or tractor in terms of horsepower and hydraulic flow?
- Mulching Depth — How deep does the rotor penetrate? Deeper capability means more thorough root elimination.
- Working Width — Wider units cover more ground per pass but require significantly more power.
- Rotor/Tooth Type — Fixed teeth vs. replaceable teeth affects maintenance cost and suitability for heavy vegetation.
- Material Diameter Capacity — Can the machine handle the stump and root sizes present on your site?
- Production Rate — How many acres per day can the machine realistically clear?
