This document provides assembly instructions for the Vicon Extra 224, 228, and 232 models, which appear to be agricultural machinery, specifically mowers or similar implements, given the references to a cutterbar, P.T.O. (Power Take-Off) shaft, and tarpaulin. The manual is a translation of the original assembly instructions, dated November 2012, with a print date of April 2012. It is published by Kverneland Group Kerteminde AS, a company specializing in agricultural machinery.

Function Description

The primary function of the device is to perform agricultural tasks, likely mowing or conditioning, as indicated by the presence of a cutterbar and a P.T.O. shaft for connection to a tractor. The assembly instructions detail the process of reassembling the machine after it has been dismantled for transport from the factory to the user. This involves attaching various components such as the three-point hitch, transmission, support legs, guards, tarpaulin, and lifting pins. The machine is designed to be robust, with specific torque settings for bolts to ensure secure and safe operation. The inclusion of a tarpaulin suggests a need to protect internal components or harvested material during operation or storage. The hydraulic cylinder and stabilizer spring indicate mechanisms for adjusting the machine's position or tension during use.

Important Technical Specifications

The manual provides critical technical specifications, primarily focusing on bolt quality and torque moments, which are essential for safe and correct assembly.

Bolt Quality and Torque Moments: A detailed table specifies torque values (in Nm and ft lbs) for various bolt dimensions (M5 to M24) across different bolt qualities (4.6, 5.8, 8.8, 10.9, 12.9). These values are for black and/or galvanized, ungreased bolts tightened on a smooth surface or a plain washer. For example, an M16 bolt of quality 8.8 requires 197 Nm (141 ft lbs) of torque, while an M24 bolt of quality 12.9 requires 1120 Nm (800 ft lbs). This precision is crucial for structural integrity and preventing loosening during operation.
Specific Fasteners: The instructions list specific fasteners used for different components, including:
- M8 x 20 bolts for the protection cap.
- M16 x 55 bolts for the bracket.
- M8 x 30 bolts and M8 lock nuts for securing the hydraulic cylinder.
- M12 x 40 bolts and M12 lock nuts for the support leg and tarpaulin frames.
- M10 x 25, M10 x 30, M10 x 19 bolts, and M10 lock nuts for various guards and tarpaulin fastenings.
- M16 x 110 bolts and M16 lock nuts for lifting pins, with a specified torque of 225 Nm (165 ft lbs).
Washer Dimensions: Various washers are specified, such as Ø30 x Ø16.5 x 15, Ø30 x Ø16.5 x 10, Ø35 x Ø21 x 21, Ø13-Ø24x2.5, Ø10.5-Ø20x2, Ø10.5-Ø30x2.5, and Ø17-Ø30x3, indicating precise fitting requirements.
Pin Dimensions: Pins of different sizes are used, including Ø20 x 90, Ø6 x 30, Ø3.5 x 30, Ø6 x 30, and Ø20 x 70.
Spring Pre-tension: For the stabilizer spring, specific pre-tension lengths are given for each model:
- Model 224: 80 mm (3").
- Model 228: 150 mm (6").
- Model 232: 120 mm (4 3/4").

Usage Features

The assembly process itself highlights several usage features:

Modular Design: The machine is designed to be dismantled into main components for transport, indicating a modular construction that facilitates shipping and potentially field repairs.
Tractor Compatibility: The mention of a three-point hitch and P.T.O. shaft confirms that the device is designed to be attached to and powered by a standard agricultural tractor.
Hydraulic Operation: The presence of a hydraulic cylinder and hydraulic hose indicates that certain functions of the machine, likely lifting or adjusting, are hydraulically controlled, offering ease of operation from the tractor cabin.
Adjustability: The stabilizer spring with adjustable pre-tension suggests that the machine's ground pressure or cutting height can be adjusted to suit different field conditions or desired outcomes.
Protection: The inclusion of guards and a tarpaulin implies a design consideration for protecting both the machine's internal components from debris and potentially protecting harvested material.
Safety Features: The manual emphasizes safety with warning symbols and instructions, indicating that the machine is designed with safety in mind, requiring proper assembly and operation to prevent accidents.

Maintenance Features

While primarily an assembly manual, some aspects hint at maintenance considerations:

Lubrication: The instruction to "Lubricate the spindle thoroughly" suggests that regular lubrication of moving parts, such as the spindle, is a key maintenance requirement to ensure smooth operation and longevity.
Component Replacement: The detailed listing of fasteners and components implies that individual parts can be replaced if damaged or worn, facilitating repairs rather than requiring full machine replacement. The emphasis on using "only original parts" for safety reasons further supports this.
Inspection Points: Instructions like "Check that the pawl is in the position shown" and "Make sure that the transmission is properly supported" during assembly suggest critical inspection points that would also be relevant during routine maintenance checks.
Protection of P.T.O. Outlet: Mounting a protection cap at the P.T.O. outlet indicates a design feature to protect this critical interface from dirt and damage when not in use, contributing to its maintenance and lifespan.
Access for Assembly/Maintenance: The sequential steps for assembly, including lifting and swinging components, suggest that the machine's design allows for reasonable access to various parts for both initial assembly and subsequent maintenance.
