Promac HSM60 Heavy Duty Skid Steer Mulcher 

Description

The Promac HSM Skid Steer Drum Mulcher is powered by a hydraulic variable torque bent axis piston motor, for drum speed control and industry leading productivity. The mulcher incorporates high strength steel and wear resistant parts that are easily replaceable, so your operation can run smoothly for years. 

The Automatic Torque Controller (ATC) increases productivity through less drum speed decay and greater drum acceleration. The Promac ATC keeps the motor at the optimum torque setting for the available hydraulic power available.

The drum accepts multiple tooling options for any ground condition. The drum itself has a Chip Production Rotor tooling system, also known as a "bite limiter" design, that makes sure you don't bite off more than you can chew, and controls discharge particle size. The drum also features easily replaceable hardened steel wire cutters that prevent wire from winding around the drive shaft between the end of the drum and frame, damaging the bearing seals. All of the holders and plates on the drum are manufactured from high strength steel for superior impact resistance and longevity.

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 HSM to stay under 2,500 lbs and maintain great machine strength and stability when operating. The frame is also low profile, resulting in outstanding operator visibility and control, and the smooth, natural, lines of the attachment make it hard for material to get hung up on the machine. The leading edge of the attachment, where it makes contact with the ground, has a flat profile that allows 1" of controlled ground contact with minimal tilt. This makes it easy to ensure you leave a nice, well mulched finish without excessive ground contact that risks damaging the cutter teeth. This also limits material from ejecting under the machine during back dragging since the chain bar and frame still impede the material at this angle.

A bolt in rear anvil provides additional performance and utility. The anvil is crucial to prevent too large of material in between the liner and the drum, which could reduce the speed of the drum or even cause jamming. The anvil is made up of  machined AR400 plate in bolted 12" sections to allow selective replacement where it is the most worn. These features give the HSM outstanding durability and longevity.

Discharge Control keeps the trajectory of the front discharge within 5' feet of the machine when operating level vs. 20-50' on other open face mulcher machines. 

Motor Case Overpressure Protection eliminates motor case failure due to inadvertent overpressure. In the event that the case drain line from the mulcher back to the carrier is blocked, or there is an over pressure of the motor case beyond the rating of the motor, a complete failure of the mulcher drive motor is a common result.  An overpressure relief valve in the case drain line will protect the motor case from overpressure.  The operator is signaled of the situation via a small amount of oil discharge through a relief port located in the operators view from the cab. Avoiding a major common expensive major failure mode.

Tooling Options

Beaver (Quad Style) Teeth: This the most economical tooling option, as the beaver teeth are cheaper to replace. These teeth can be rotated to get the most life out of them, and are seen commonly throughout the industry. These teeth also take less of a bite than the chipper teeth and are therefore slightly less productive but great for maintaining drum speed on lower flow machines.

Chipper Teeth: These can be sharpened, reversed, and replaced easily. They are extremely efficient at mulching wood and last between 40-100 hours per side depending on conditions (They deteriorate quickly in rocky conditions). 

Double Carbide Teeth: These teeth are not efficient at mulching and cannot be sharpened, but they are extremely tough, lasting up to 500 hrs and holding up much better in rocky conditions. 

Combo Configurations: The outer teeth on the drum are generally more exposed to rocks and dirt, and do less actual mulching than the center of the drum. For this reason it is recommended that you choose a combo tooth configuration. You can choose either Chipper or Beaver teeth, and the outer 3 rows (12 total teeth) will be replaced with Double Carbide teeth for improved durability. 

Hydraulic brake: A hydraulic delay that engages the brake after a 5 second delay.  The drum comes to a full stop in about 20 seconds (5 second delay + 10-15 seconds to stop).
