- Four ways to mulch make the disc mulcher a versatile and effective land-clearing attachment
Features & Benefits
Powerful Cutting and Mulching Action
Machined from high-strength one-inch-thick steel, the disc meets strict specifications for well-balanced rotation and high-speed cutting performance. The disc mulcher can cut trees up to 14 inches in diameter and turn trees up to 6 inches in diameter into beds of mulch. The disc mulcher can cut at ground level and supports an impressive vertical reach.
Hardened Steel Teeth
Case-hardened steel teeth are fixed to the inside of the deck shell, and they mulch material as the rotating disc carries trees and brush through the attachment. These four-point teeth can be easily sharpened and rotated to maximize efficiency. The planter knives in the center of the disc eliminate dead zones for effective, easy land clearing, regardless of the attachment’s position.
High-Torque Hydraulic Gear Motor
The hydraulic gear motors efficiently handle the bulk of tough land-clearing applications with ease. These gear motors generate high torque and collectively support three hydraulic flow ranges: standard, high and super flow. The gear motors also feature a relief valve to protect against overpressurization.
Push Bar
A push bar on the front of the disc mulcher helps operators direct the fall of trees and heavy brush for productive processing.
Simple Maintenance
The spindle bearings are lubricated with gear oil that should be replaced once every year or every 500 hours, whichever comes first. Operators have easy access to the disc teeth, the motor hardware and the spindle hardware, which should be inspected daily, or every 10 hours, to ensure optimum performance.
Protective Motor Cover
A steel covering shields the hydraulic motor, protecting it from contact and damage.
Two Intake Configurations
The disc mulcher features two intake configurations to optimize the intake flow of varying tree sizes and material densities.
Top Tasks
Clear trees and brush for:
- Utility line and right-of-way maintenance
- Site preparation
- Rural area and vegetation maintenance
How It Works
The disc mulcher functions like a flywheel, storing kinetic energy to slice through tough material and shred it into mulch. The stored energy minimizes the performance demands on your loader and helps reduce operating temperatures.
There are several techniques for operating the disc mulcher, making it a versatile and effective land-clearing attachment.
- When felling trees, drive the left side of the disc into the trunk and use the push bar to tip the tree away from your loader.
- For top-down mulching, use the bottom of the left side of the disc, and tilt back as you lower the mulcher on top of stumps and small trees to shred material to ground level.
- To pull trees into the mulching chamber from the bottom up, drive the right side of the mulching disc straight into the trunk to make the cut. Then tilt the mulcher back, feeding the tree into the intake chute.
- For backdragging, tilt the disc mulcher forward and work the material into the ground, leaving a clear surface as your machine moves back.
Required Components
The following components are required to operate this attachment and must be purchased separately:
Forestry Application Kit Is Required
Designed to help protect you and your investment in the toughest conditions, the forestry application kit must be installed on the loader to operate the disc mulcher attachment. The exclusive forestry door protects against flying debris and objects.
The Forestry Application Kit Includes:
- Fire extinguisher: Mounted in the cab for quick access in an emergency.
- Forestry door: The Bobcat ¾-inch laminated polycarbonate forestry door is required for operation of the disc mulcher. Emergency exit allows for removal of front door, if necessary.
- Front and rear light guards: Ensures branches and debris won't break lights.
- Hydraulic quick coupler guard: The guard, along with no exposed fittings on the hoses, helps protect the couplers, hoses and wire harness from falling trees and branches.
- Level II FOPS (Meets ISO 3449): Protects operator and cab from falling trees and objects.
- Lift cylinder debris shields (M-Series Only): Protects lift cylinders and reduces material buildup in the engine compartment.
- Muffler guard: Protects tailpipe from damage and reduces material buildup in the engine compartment.
- Polycarbonate top, rear and side windows: Adds operator protection and maximizes visibility (¼-inch or ½-inch polycarbonate).
Options & Accessories
- Optional piston motor (60-inch model only): The optional piston motor increases disc rotation to 1,290 rpm at full speed for more productivity. The piston motor also reduces the time required to bring the disc to full speed, as well as the disc's recovery speed during mulching. The piston motor is only available with the 60-inch disc mulcher and can be used with high-flow hydraulics and super-flow hydraulics.
- Optional chain guard: The disc mulcher's chain guard obstructs debris thrown toward the rear of the attachment.
- Optional carbide teeth: Upgrade to optional carbide teeth for extended service life and enhanced performance. Carbide teeth are designed to withstand abrasion and extreme ground contact. They're ideal for use on rocky terrain and in operation conditions with repetitive ground contact.
