This document is a service manual for New Holland ProTed™ rotary tedders, specifically models 3417, 3625, and 3836. It provides essential information for qualified dealership personnel to perform repair and maintenance work, emphasizing strict compliance with instructions and the use of special tools. The manual was first published in English in March 2013, with part number 47477424.
Function Description:
The ProTed™ series are rotary tedders, agricultural implements designed to spread and aerate cut forage crops (like hay) to accelerate drying. This process helps prevent spoilage and ensures high-quality feed. The manual covers various aspects of these machines, including their main gearbox and drive, power take-off (PTO) systems, hydraulic systems, hitches, drawbars, implement couplings, electrical systems, and attachment/header frames.
Important Technical Specifications:
- Models Covered: ProTed™ 3417, ProTed™ 3625, ProTed™ 3836.
- Gearbox Oil (All Models): TUTELA HYPOIDE EP GEAR LUBE SAE 80W-90.
- Capacities:
- ProTed™ 3417 Main Gearbox: 0.75 L (0.8 US qt).
- ProTed™ 3625 Main Gearbox: 1.2 L (1.3 US qt).
- ProTed™ 3625 Rotor Gearbox: 0.2 L (0.2 US qt).
- (Capacities for ProTed™ 3836 are listed in the table of contents but not detailed in the provided pages, suggesting they would be similar to the 3625 or larger).
- Fastener Torque Specifications: The manual provides detailed tables for minimum tightening torques for both metric non-flanged and metric flanged hardware (Class 8.8 and 10.9 bolts and nuts). Torque locknuts require 10% above standard hardware torque value.
- Hydraulic Fittings: All hydraulic fittings on these machines are British Standard Pipe thread (BSP) and are NOT interchangeable with National Pipe Thread (NPT). Specific Loctite sealants (567 PST, 565 PST, 545 for high filtration/zero contamination systems) are recommended for installation.
- Product Identification: Each model has a PIN plate located on the right-hand side of the main frame. The PIN plate includes information such as Model, Country of origin, Model year, Year of construction, Weight (kg), and the Product Identification Number (PIN). This information is crucial for ordering spare parts.
Usage Features:
While primarily a service manual, it implicitly highlights usage features through its maintenance guidelines. The tedders are designed for agricultural use, specifically for spreading and aerating forage. The presence of PTO, hydraulic, and electrical systems indicates that these machines are powered by a tractor and likely feature hydraulic controls for various functions (e.g., folding, height adjustment) and electrical components for lighting or sensors. The different models (3417, 3625, 3836) likely correspond to varying working widths or number of rotors, catering to different operational scales. The emphasis on proper torque for fasteners and hydraulic fittings ensures safe and efficient operation of the machinery.
Maintenance Features:
- Qualified Personnel: All repair and maintenance work must be carried out by qualified dealership personnel.
- Special Tools: The use of special tools, specifically researched and designed by NEW HOLLAND AGRICULTURE, is essential for reliable, efficient, and safe repair operations.
- Shimming: For adjustments, individual shims must be measured with a micrometer, and their values added up, rather than relying on measuring the entire set or rated values.
- Rotating Shaft Seals: Specific installation procedures are outlined, including soaking seals in oil, thorough cleaning of the shaft, correct sealing lip orientation (considering hydrodynamic lips and shaft rotation), lubricating the lip, filling the gap between lips on double lip seals with grease, and using a flat punch or seal installation tool for insertion. Protective guards are recommended to prevent damage during installation.
- O-ring Seals: Must be lubricated before insertion to prevent overturning and twisting, which could compromise sealing efficiency.
- Sealing Compounds: Apply as specified, preparing surfaces according to product container directions.
- Spare Parts: Only CNH Original Parts or NEW HOLLAND AGRICULTURE Original Parts are to be used to guarantee quality, duration, and safety. When ordering, the machine model, PIN, and part number are required.
- Electronic/Electrical System Protection: Strict guidelines are provided for protecting these systems during charging and welding, including disconnecting battery ground cables, avoiding short circuits, and proper placement of welding clamps.
- Hydraulic Contamination: Identified as a major cause of malfunction. The manual details how contamination can enter the system (e.g., during oil changes, component disassembly) and lists common problems caused by both microscopic (e.g., leaking cylinder rod seals, difficult control valve spools, high operating temperature) and visible contamination (e.g., metal/dirt particles, air, dark/thick oil, burned oil odor, water). A portable filter is recommended to clean the hydraulic system if contamination is found.
- Ecology and Environment: Emphasizes responsible handling and disposal of chemical and petrochemical products (oils, fuels, antifreeze, cleaning agents, batteries) in accordance with legislation and environmental best practices. It advises against skin contact with these substances, burning contaminated fuels/oils, mixing drained fluids, and releasing air-conditioning gases into the atmosphere. Prompt repair of leaks in cooling or hydraulic systems is also stressed.
- Safety Rules: Highlights personal safety with DANGER, WARNING, and CAUTION messages, and machine safety with NOTICE messages. Users are instructed to read and understand all safety messages.
