Seco ATI-991364-02 Apache Bullseye Magnetic Mount DMM2 for Flat-Back Bulldozer Blade

Overview

The Spectra ATI-991364-02 Apache Bullseye Magnetic Mount DMM2 is a heavy-duty magnetic mounting solution engineered specifically for flat-back bulldozer blades and grading equipment in light-to-mid-duty earthwork operations. Delivering an impressive 900 lbs of magnetic holding force, this professional-grade mount securely positions Spectra LR-series and Apache Bullseye laser receivers without requiring drilling, welding, or permanent modifications to your blade.

Designed for contractors who demand reliability and efficiency, the ATI-991364-02 eliminates downtime associated with traditional mounting methods. Simply position the magnetic mount on your flat-back dozer blade, attach your machine control receiver, and you're ready for precision grading within minutes. The robust construction withstands the harsh vibration, shock, and environmental conditions typical of earthmoving jobsites, while the quick-release design allows you to transfer receivers between machines or remove them for secure overnight storage.

This mount is particularly valued by grading contractors, site developers, and municipal operators running flat-back blade configurations who need a non-permanent, highly secure mounting solution that won't compromise blade integrity or require specialized installation skills. Compatible with Spectra's complete ecosystem of Apache and Bullseye laser receivers, the ATI-991364-02 represents a cost-effective alternative to fabricated brackets while maintaining the precision positioning required for grade control work.

Job Applications

• Residential Site Development: Perfect for subdivision grading where operators need to maintain precise elevations across multiple lots without permanently modifying equipment. The magnetic mount allows quick receiver repositioning as grade requirements change throughout the project, while the non-permanent installation preserves equipment resale value.
• Municipal Road Construction: Ideal for city and county road departments running flat-back blade configurations on grading work. The 900-lb holding force ensures receiver stability through pothole patching, shoulder work, and finish grading operations, while the tool-free installation means operators can mount and remove receivers without specialized maintenance staff.
• Agricultural Land Leveling: Excellent for farm contractors performing field grading and drainage work where precision is critical but equipment often transitions between laser-guided and conventional work. The magnetic mount enables farmers to quickly install laser receivers for land plane operations and remove them for standard tillage work without compromising blade integrity.
• Small Commercial Pads: Well-suited for building pad preparation on light commercial projects where finish grade tolerances must be tight. The secure mounting prevents receiver drift during compaction passes and fine grading, ensuring consistent elevation control that meets architectural specifications without the need for permanent bracket fabrication.
• Parking Lot Grading: Outstanding for asphalt paving contractors performing subgrade preparation on parking areas and access roads. The quick-release design allows crews to transfer the receiver between multiple machines on large projects, maximizing equipment utilization while maintaining the grade accuracy required for proper drainage and ADA compliance.
• Trench Backfilling and Finish Work: Highly effective for utility contractors using dozers for trench backfill and restoration to existing grade. The magnetic mount provides secure receiver positioning during vibration-intensive compaction work, while the non-permanent installation means the same blade can be used for rough dozing without laser equipment in place.

FAQ

Will this magnetic mount work on curved or C-frame dozer blades?

No, the ATI-991364-02 is specifically engineered for flat-back bulldozer blades and grading blades. Curved blades, C-frame configurations, and six-way blades require different mounting solutions. The flat contact surface is essential for achieving the full 900-lb magnetic holding force. For curved blade applications, consider bolt-on universal brackets or blade-specific mounting kits designed for your equipment configuration.

How do I know if my blade surface is clean enough for proper magnetic contact?

The blade mounting surface should be free of thick mud, loose rust, paint buildup, or debris. Light surface rust is acceptable and won't significantly reduce holding force. Before each use, wipe the blade contact area and the magnetic mount surfaces with a rag to remove loose material. You'll know the mount is properly seated when you feel strong resistance when positioning it and cannot easily slide it once placed. If the mount slides too easily, further surface cleaning is required.

Can I leave the magnetic mount attached to the blade overnight or during transport?

While the 900-lb holding force is substantial, best practice is to remove the receiver and mount assembly during transport and overnight storage. This prevents theft, protects the equipment from unnecessary weathering, and eliminates the small risk of mount displacement during trailer loading or rough transport. The tool-free installation takes only minutes, making daily mounting and removal practical for most operations.

What's the difference between DMM2 and other Apache mount configurations?

DMM2 refers to the specific receiver bracket configuration and mounting pattern used with this magnetic mount. It's designed for dual-mast machine control receivers commonly used on dozer applications. This differs from single-mast configurations (DMM1) used on smaller receivers and excavator applications. Always verify your laser receiver's mounting configuration matches the DMM2 specification before purchasing to ensure proper fit and function.
