Light on Weight. Heavy on Performance.
Enhanced, innovative design with new optional features
The upgraded LDM Series features two new optional features to enhance performance and safety. First, a chain with a fixed rear bar has been added to increase efficiency while reducing material discharge from the rear, resulting in a safer working experience. Second, a custom-engineered pin mount is now available, perfectly suited to your carrier, ensuring seamless integration with your equipment.
Designed and manufactured in North America, the LDM Series mulcher attachment has been rigorously tested and approved on the rugged west coast, by the very people it was designed for. You can trust its durability and performance in the toughest conditions.
With the LDM Series, you have the flexibility to configure your hydraulic flow as low as 15 GPM @ 5000 PSI, making it adaptable to a wide range of applications. It can efficiently tackle brush and trees. Available in 30" and 50" large cut widths, and with a choice of three different cutter teeth to suit your working conditions, you can tailor it to your specific requirements.
The mulcher is driven by a variable-tension hydraulic bent-axis piston motor, paired with our Promac Automated Torque Control (ATC) for optimal efficiency and performance. Additionally, Promac uses high-strength steel and wear-resistant components that are easily replaceable, ensuring smooth operation for years to come.
Upgrade to the improved LDM Series mulcher attachment and experience enhanced performance, safety, and durability for your forestry operations. Trust Promac for top-quality equipment that meets your needs and exceeds your expectations.

Standard Features at a Glance
The Drum
The drum has the Promac “Chip Production Rotor” tooling system known in the industry as a “bite limiter”. This feature helps control discharge size while maintaining RPM. All holders and plates on the drum are manufactured from high strength steel for superior impact resistance and longevity.
The Teeth
The drum accepts multiple tooling options to suit any budget, performance and ground condition, including: Proprietary rotatable knives for the best mulching performance in sand or soil, double carbides for longevity in rock and economically priced beaver teeth for good performance in most conditions.
The Frame
The frame is made of fully welded high strength steel and a boxed in design, which provides better rigidity than other open-end designs. This allows the LDM Series to be light weight and maintain great machine strength and stability when operating. The frame incorporates a large ‘pusher pad’ to permit the operator to ‘push’ on the heal of the mulcher without damaging the machine.
The Add-ons
Optional Chain Bar: The optional chain bar was developed based on customer feedback and launched in early 2021. This is a simple and effective way to minimize the discharge of material out the rear of the mulcher while providing a sloped surface to guide the standing trees into the drum.
The Motor
The hydraulic motor is directly coupled to the drum via an isolation coupler. This efficient system provides shock load protection for the drive motor. The motor also includes the Promac Automatic Torque Controller (ATC) as standard.
Versatile Tooling Options
The LDM series can be fitted with tools specifically tailored to the job requirements and the desired final product. The machine is equipped with standard rotatable knives which can easily be sharpened, reversed, or changed. Double carbides are suggested to get the best results in harsh or difficult conditions. The teeth of a Beaver are an excellent alternative for most of your operational needs.
