Overview

This document is the owner's manual for the Cobra Garden Tractor, models LT62MRL (TRM162-L224) and LT62HRL (TRM162H-L224). It provides comprehensive instructions for safe operation, maintenance, and troubleshooting of the ride-on mower.

Function Description:

The Cobra Garden Tractor is a ride-on lawnmower designed for mowing garden lawns. It features a cutting mechanism with a single blade and a grass catcher for collecting clippings. The tractor is available with two transmission types: manual (LT62MRL) and hydrostatic (LT62HRL), offering different driving experiences and speed control. The manual transmission model has four forward gears and one reverse gear, while the hydrostatic model provides stepless speed control via separate pedals for forward and reverse. The machine is equipped with various safety devices, including a brake system contact switch, a mower cutting mechanism contact switch, a seat contact switch, and a grass catcher contact switch, all designed to prevent operation under unsafe conditions.

Usage Features:

The tractor emphasizes safety, requiring users to wear sturdy footwear and long trousers, and to remove debris from the mowing area. Refueling must be done outdoors, away from ignition sources, and with a cool engine. The engine should not be started in confined spaces. Operation on slopes is restricted, with a maximum longitudinal gradient of 15° (27%) and lateral gradient of 10° (18%). Special care is advised on slopes, including maintaining low speeds and avoiding sudden stops or turns. The mower cutting mechanism should be disengaged before crossing non-grass surfaces.

Starting the engine requires the brake/clutch pedal to be fully pressed and the selector lever in neutral (for manual transmission) or the brake pedal depressed (for hydrostatic transmission). The mower cutting mechanism must be disengaged before starting. Cutting height is adjustable via a lever, and it's recommended to start mowing at the highest setting, especially in long or wet grass, then reduce it for a second pass if needed. The mower cutting mechanism should only be engaged after the engine has warmed up for about a minute and at the highest cutting position. Reverse mowing is possible but requires additional care and is speed-limited, especially when the cutting mechanism is engaged. The grass catcher has a fill-level sensor and can be emptied from the operator's seat.

Maintenance Features:

Regular maintenance is crucial for optimal function and longevity. The manual provides a maintenance schedule, detailing tasks to be performed before each use, after each use, after the first 5 hours, every 25 operating hours, every 50 operating hours, and before storage. Key maintenance tasks include:

  • Engine Oil: Checking the oil level before each use and changing it periodically. The engine is shipped without oil and must be filled before first use.
  • Fuel: Handling fuel with caution, ensuring proper filling and avoiding overfilling.
  • Tyre Pressure: Checking regularly to ensure a level cutting deck.
  • Mower Cutting Mechanism: Inspecting blades, securing bolts, and the mower deck for wear or damage. Blades should be replaced in sets to maintain balance.
  • Air Filter: Cleaning the air filter according to the schedule, ensuring no dirt enters the engine intake port during cleaning.
  • Spark Plug: Checking and replacing the spark plug as necessary, ensuring the correct electrode gap.
  • Bowden Cable Adjustment: Adjusting the Bowden cable for the mower cutting mechanism if it cannot be switched on or off correctly.
  • Cutting Height Adjustment: Adjusting the mower cutting mechanism if the cutting height is incorrect due to wear or tyre changes.
  • Starter Battery: Charging the battery before storage or if the machine will not be used for a long time. Instructions for safe handling and charging are provided, emphasizing polarity and current limits.
  • Cleaning: Cleaning the grass catcher, deck, engine, and transmission after each use. High-pressure cleaners should not be used on the engine, transmission, or electrical system. The mowing system can be cleaned by connecting a water hose to a dedicated fitting.

The manual also includes troubleshooting tips for common issues like the engine not starting, grass catcher not filling, or the ride-on mower vibrating excessively. For complex repairs or issues with safety devices, contacting a service dealer is recommended.
