1. Product Introduction
Engineered for demanding agricultural operations and intensive tillage systems, the Tine Holder LH (Part No. 34069810) and Tine Holder RH (Part No. 34069710) deliver unparalleled durability and dimensional stability. These components feature a highly engineered curved structure designed for optimal load distribution and seamless integration with complex tillage assemblies.
Manufactured from high-grade 52CrMnMoV alloy steel (or equivalent) through advanced investment casting and 5-axis CNC machining, these holders provide exceptional resistance to soil abrasion and high-impact field loads.
The Tine Holder RH design features a precisely mirrored 45° angled bracket compared to the LH model, ensuring perfectly balanced stress distribution in symmetrical tillage systems.

3. Tine Holder Key Features
- Exceptional Load Bearing: Designed to withstand severe soil abrasion and immense impact loads up to 8,000 lbs, making them ideal for heavy-duty plowing and tillage.
- Precision Engineering: 5-axis CNC machining guarantees bolt hole alignment within ±0.05mm, ensuring frictionless assembly and reducing shear stress on fasteners.
- Optimized Geometry: Incorporates reinforced flanges and uniquely tapered bolt channels designed specifically to prevent soil buildup during wet field conditions.
- Symmetrical Balance: The Tine Holder RH model features a precisely calculated 45° angled bracket that mirrors the LH model, preventing unilateral wear and tear on the machinery’s chassis.
- Rigorous Quality Control: Every production batch undergoes 150% load testing, magnetic particle inspection for micro-cracks, and highly accurate CMM dimensional verification.
4. Manufacturing Process
Our IATF 16949-certified production process ensures absolute metallurgical consistency:
| Investment Casting: | Forms the complex curved geometries and tapered channels with a tight geometric accuracy of ±0.1mm. |
| 5-Axis CNC Machining: | Refines critical load-bearing surfaces and pivot points to a flawless Ra 3.2μm smoothness. |
| Comprehensive Thermal Cycle: | Normalizing: Heated to 900-920°C to refine the grain structure. Annealing: To relieve internal casting stresses. Oil Quenching: Rapid cooling at 850°C to harden the alloy. Tempering: Sustained heating at 540-600°C to achieve the precise HRC 32-36 core hardness with a uniform microstructure. |
| Surface Preparation: | MIL-SPEC shot blasting (SAE J444) cleans the surface and provides the ideal texture for optimal coating adhesion. |
| Surface Treatment: | Application of black baking varnish, electro-galvanizing, or coating. |
5. Applications
These tine holders are critical structural components for:
| Tillage Machinery: | Cultivators, subsoilers, and heavy-duty plows. |
| Agricultural Equipment: | Large-scale seeders and soil preparation implements. |
| Custom Agricultural Rigs: | Systems requiring robust, balanced, symmetrical suspension and tine mounting capabilities. |
6. Mating/Matching Parts
| Fasteners: | Fully compatible with standard ISO 4017 heavy-duty hex head bolts (M16-M24). |
| Tillage Tools: | Mounts seamlessly with high-tensile cultivator tines and sweeps. |
| Washers & Nuts: | Compatible with hardened steel lock nuts and heavy-duty flat washers to maintain torque specifications under extreme vibration. |
7. Important Notes for Bulk Purchasing
- Custom Coatings: While a black baked finish is standard, for customers operating in high-humidity environments, we strongly recommend special coatings that provide over 800 hours of salt spray resistance.
- Symmetrical Ordering: For initial builds and major overhauls, LH (34069810) and RH (34069710) should be ordered in matched pairs to maintain structural balance.
- Documentation: Material test reports (MTRs), CMM inspection logs, and magnetic particle inspection certificates can be provided alongside bulk shipments upon request.
8. Frequently Asked Questions (FAQ)
Q: What is the primary difference between the LH (34069810) and RH (34069710) models besides orientation?
A: Mechanically, the RH model features a mirrored 45° angled bracket designed to complement the LH model. Additionally, there is a slight variance in maximum rated impact load capacity (8,000 lbs for LH vs. 7,500 lbs for RH) due to the specific stress distribution dynamics of symmetrical tillage assemblies.
Q: Are these components suitable for highly abrasive, rocky soil?
A: Yes. The 52CrMnMoV alloy steel construction paired with our rigorous 4-step heat treatment cycle (resulting in HRC 32-36 hardness) provides exceptional resistance to both blunt impact and continuous abrasion in rocky or densely packed soil.
Q: Can you accommodate custom surface treatments for high-corrosion environments?
A: Absolutely. Aside from our standard finishes, we offer electro-galvanizing (ISO 1461 compliant) and coatings, which are specifically engineered to withstand wet field conditions and prevent long-term rust accumulation.
Q: How do you guarantee the absence of internal casting defects?
A: Under our IATF 16949 certification, 100% of critical batches undergo magnetic particle inspection to detect any micro-cracks or subsurface anomalies, coupled with 150% physical load testing.
