About this file
This is a Statement of Objectives for the acquisition of a stump grinder attachment under federal contract W50S9H26QA022. The contracting agency is Volk Field Civil Engineering, which seeks to remove stumps obstructing drivable paths essential for security checks and base operations.
The stump grinder attachment must be compatible with Bobcat T250 and Bobcat 770 skid-steer loaders currently owned by the government. Key performance specifications include a minimum cutting wheel diameter of 32 inches, hydraulic flow operating range of 20–42 GPM, system pressure capability up to 4,250 PSI, cutting depth up to 20 inches in a single pass, and stump grinding capacity of 8–28 inches in diameter. The attachment must operate at approximately 7–16 RPM to provide controlled, high-torque cutting. Physical requirements specify a minimum operating weight of 1,350 lbs and a Universal Skid Steer/Compact Track Loader quick-attach mounting interface integrated into the attachment body without requiring modifications to the carrier equipment. The attachment must be equipped with a 2-speed hydraulic motor and staggered AR500 steel cutting blades designed for low maintenance and extended service life. The unit must effectively cut through feeder roots and operate in rocky or compacted soil conditions while minimizing debris throw and reducing kickback, flying debris, and operator risk through low-RPM, high-torque operation.

W50S9H26QA022 – STUMP GRINDER ATTACHMENT
ACQUISITION OBJECTIVE
To acquire a high-torque, low-RPM stump grinder attachment capable of ef�iciently removing the large number of stumps currently obstructing drivable paths essential for security checks and base operations. This capability will signi�icantly increase the speed and effectiveness of stump-clearing efforts compared to the existing equipment, while also enhancing overall safety for operators and bystanders during on-base stump-grinding activities.
MINIMUM SPECIFICATIONS REQUIREMENTS
Stump Grinder Attachment Must be compatible with Bobcat T250 and Bobcat 770 models currently owned and operated by Volk Field Civil Engineering
PERFORMANCE REQUIREMENTS
• Bit Diameter - Minimum cutting wheel diameter of 32 inches.
• Hydraulic Flow - Must operate within a hydraulic �low range of 20–42 GPM, fully compatible with the hydraulic output of Bobcat T250 and 770 skid-steer models.
• Operating Pressure - Capable of handling system pressures up to 4,250 PSI.
• Boring Depth - Able to achieve up to 20 inches of cutting depth in a single pass.
• Stump Capacity - Must grind stumps 8–28 inches in diameter in one pass.
• RPM Range - Operates at approximately 7–16 RPM to provide controlled, high-torque cutting.
PHYSICAL REQUIREMENTS
• Operating Weight - Attachment weight shall be no less than 1,350 lbs. to ensure stability and cutting force.
• Mounting Interface - Must include a Universal Skid Steer / Compact Track Loader (SSL/CTL) quick-attach interface integrated into the attachment body.
• Compatibility - Attachment must be fully compatible with Bobcat T250 and Bobcat 770 skid-steer loaders without requiring modi�ication to the carrier equipment.
COMPONENT REQUIREMENTS
• Hydraulic Motor - Equipped with a 2-speed hydraulic motor to support variable torque and speed operations.
• Cutting Blades - Cutting system shall use staggered AR500 steel blades, designed for low maintenance and extended service life.
• Root and Soil Capability - Must effectively cut through feeder roots and operate in rocky or compacted soil conditions.
SAFETY REQUIREMENTS
• Operational Safety - Must minimize debris throw and ensure safe operation for personnel and bystanders during stump-grinding activities.
• Low-RPM Safety - Low-RPM, high-torque operation required to reduce kickback, �lying debris, and operator risk.
COMPATIBILITY REQUIREMENTS
• Must be fully compatible with Government-owned SSL/CTL platforms meeting the hydraulic and mounting speci�ications listed above, including Bobcat T250 and Bobcat 770 models.
