This document is a product manual for the TMG Industrial ATV Tow-behind Finish Mower, specifically models TMG-AFN48 and TMG-AFN60.

The TMG Industrial ATV Tow-behind Finish Mower is designed for efficient and versatile lawn and field maintenance, particularly suited for use with an ATV, UTV, or other utility vehicles. Its tow-behind design allows for easy attachment and operation, making it ideal for large areas such as lawns, fields, parks, and golf courses. The mower is equipped with a gasoline engine, providing independent power for cutting, which allows it to be used with a variety of tow vehicles without relying on their PTO systems.

Function Description:

The primary function of this device is to cut grass and vegetation in large areas. It operates as a finish mower, meaning it is designed to provide a clean, even cut, similar to a lawnmower, rather than a rough cut like a brush hog. The mower features multiple blades (the exact number is not specified but implied by the "finish mower" designation and typical designs) that rotate horizontally to cut grass. The cutting height is adjustable, allowing users to customize the lawn finish according to their needs. The tow bar offset is also adjustable, which enables the mower to cut areas that are difficult to reach directly with the tow vehicle, such as under trees or along fences, without the tow vehicle needing to drive over the area. This feature helps prevent compaction of the soil and damage to the grass.

Important Technical Specifications:

While specific engine horsepower, cutting width, or weight are not detailed in the provided excerpts, the model numbers TMG-AFN48 and TMG-AFN60 typically indicate cutting widths of 48 inches and 60 inches, respectively. The manual includes detailed torque specifications for various bolts and cap screws, indicating a robust construction. For example, SAE 2 bolts range from 0.5 N.m (0.4 lb-ft) for M3 to 2600 N.m (1917 lb-ft) for M36. SAE 5 and SAE 8 bolts also have corresponding torque values, emphasizing the importance of proper fastening for safety and performance. The inclusion of metric torque specifications (M3 to M36) further suggests a design that accommodates various fastener types and ensures structural integrity. The engine is gasoline-powered, and the manual details procedures for changing engine oil, tensioning and replacing belts, and troubleshooting engine-related issues.

Usage Features:

The mower is designed for ease of use and maneuverability.

Starting and Stopping: The manual provides clear instructions for starting the mower using a choke control and a key switch, and for stopping it by turning the key to the STOP position.
Cutting Height Adjustment: The cutter deck height is adjustable, allowing users to raise or lower the deck to achieve the desired cutting height. This is typically done by adjusting the wheels or a central mechanism.
Tow Bar Offset Adjustment: This feature allows the mower to be offset from the tow vehicle, which is particularly useful for mowing close to obstacles or in areas where the tow vehicle cannot safely drive.
Tow Vehicle Recommendations: The manual recommends using a tow vehicle with a minimum of two or four-wheel drive, such as a compact or sub-compact tractor, utility vehicle (UTV), all-terrain vehicle (ATV), or lawn/garden tractor with sufficient horsepower (e.g., 17 HP and above for a 500 lbs. mower, 30 HP and above for a 700 lbs. mower). It explicitly states that riding lawn mowers with engines under 17 HP and weighing less than 500 lbs. are not suitable for use on slopes greater than 5 degrees.
Safety Features: The manual emphasizes safety with warnings about keeping hands and feet away from moving parts, avoiding contact with spinning blades, and maintaining a safe distance from the mower during operation. It also includes warnings about operating on slopes, avoiding obstacles, and wearing appropriate safety gear.

Maintenance Features:

The manual provides comprehensive guidelines for routine maintenance and troubleshooting to ensure the longevity and optimal performance of the mower.

Engine Oil Change: Detailed steps are provided for draining old oil and refilling with new engine oil, along with instructions for checking the oil level.
Belt Tension and Replacement: Instructions are given for checking and adjusting belt tension, as well as for replacing worn or damaged belts, including the starting wire harness plug, pulley cover, and various bolts and nuts.
Storage: Recommendations for proper storage during the off-season or when not in use are included, such as cleaning the mower, inspecting for wear, and repairing any damage.
Troubleshooting Guide: A detailed table lists common problems, their causes, and corresponding corrections. This includes issues like the engine not starting (due to disconnected wiring harness, no prime, bad spark plug, empty fuel tank, dirty carburetor, dirty air filter, engine flooded, incorrect throttle control, stale gasoline, or defective throttle control lever), defective ignition, battery no charge, engine running poorly, engine overheating, engine not stopping, poor mower performance (dull blades), and mower vibrations (loose nuts/bolts, broken mower head).
Ordering Replacement Parts: The manual outlines the process for ordering replacement parts, requiring the material code, part description, quantity, and model/serial number.
Illustrated Parts Breakdown: Detailed exploded diagrams with numbered parts and corresponding part lists are provided for various assemblies, including the ATV Finish Mower, Wheel Frame Mount, Tow Bar, Spindle, Engine Mount, and Battery Box. This facilitates easy identification and ordering of specific components.

The manual stresses the importance of reading and understanding all instructions before operating the mower to ensure safe and effective use. It also highlights the need for regular inspections and maintenance to prevent breakdowns and extend the life of the equipment.
