Important Technical Specifications:
While specific numerical technical specifications like engine horsepower or mower deck width are not explicitly stated in the provided text, the manual implies several key technical aspects through its parts lists and diagrams:
- Electrical System: Includes a 12 Volt 25 AMP battery, a 30 AMP auto green fuse, a 3 AMP DC @ 3600 RPM charging system output, and a 5 AMP AC @ 3600 RPM lighting system output. The ignition switch has positions for OFF, RUN/LIGHT, RUN, and START. The system supports both single and twin-cylinder engines (indicated by "2 PLUGS ON TWIN CYL. ENGINES" for spark plug gap).
- Chassis and Enclosures: Features a chassis LT stamping 98, a drawbar, and various panels for the hood, fender, and grille. The design includes a bumper for protection.
- Drive System: Utilizes a transmission assembly, a drive V-belt, pulleys (transmission, idler, engine), and a clutch/brake pedal mechanism. The transaxle is a Hydro Model Number 0319-0500.
- Steering System: Comprises a steering wheel, front axle assembly, spindles, drag links, and a gear sector for directional control.
- Engine: The manual references a Briggs Model No. 287707 engine, indicating a gasoline-powered internal combustion engine. It includes components like a muffler, fuel tank, and spark arrestor (optional).
- Mower Deck: A 42-inch mower deck is referenced (e.g., "Housing Asm MWR 42" HL MCH T-Path," "Blade Mower 42" High Lift," "Baffle Vortex 42"). It includes mandrels, blades, pulleys, and a mower lift lever mechanism for height adjustment.
- Transaxle: Specifically identified as a Hydro Model Number 0319-0500, indicating a hydrostatic transmission for smooth, variable speed control. It contains housing, gears, bearings, seals, and an oil filter element.
- Tires and Wheels: Features front and rear rims, tires (e.g., "Tire, Rear TS. 18 x 9.5 - 9 C. Service"), tubes (not furnished), and axle caps.
Usage Features:
- Identification of Parts: The primary usage feature of this manual is to enable customers to accurately identify specific parts for their WEX145H42B lawn tractor. Each part is assigned a key number and part number, accompanied by a description.
- Ordering Repair Parts: The manual explicitly states that when ordering parts, customers should provide the product ("Tractor"), model number ("WEX145H42B"), part number, and part description to ensure correct ordering.
- Electrical Schematic: A detailed schematic is provided for the electrical system, which is crucial for troubleshooting and understanding the wiring of components like the battery, fuse, solenoid, starter, ignition switch, hour meter, fuel shut-off solenoid, ignition unit, charging system, alternator, and headlights.
- Component Brightness: The manual notes that the tractor's lights are connected to their own electrical source, causing their brightness to change with engine speed (dim at idle, brighter when speeded up). This is an operational characteristic rather than a defect.
- Model Number Location: The model number for the tractor can be found on the fender under the seat, a useful piece of information for owners.
Maintenance Features:
- Assembly/Disassembly Guidance (Limited): While the manual is not recommended as a primary guide for assembling or disassembling the tractor, its detailed illustrations and parts lists indirectly aid in understanding how components fit together, which can be beneficial during repair.
- Wiring Security: A note advises that if wiring insulated clips are removed for servicing, they should be replaced to properly secure the wiring, highlighting a specific maintenance best practice.
- Component Dimensions: All component dimensions are given in U.S. inches, with a conversion note (1 inch = 25.4 mm), which is helpful for mechanics and parts suppliers.
- Limited Warranty: The manual includes a "LIMITED WARRANTY" section, outlining the manufacturer's warranty for one year from the date of purchase, covering defects in materials and workmanship. It specifies exclusions (e.g., engine, battery after 90 days, normal wear, belts, blades, standard hardware) and conditions (proper assembly, operation, and maintenance). It also provides contact information for warranty claims and service departments in the U.S. and Canada.
- Battery Maintenance: The warranty section mentions that the battery must be maintained in accordance with furnished instructions, indicating a user-responsibility aspect of maintenance.
- No Disassembly Guide: The manual explicitly states it should not be used as a guide to assemble or disassemble the tractor, implying that actual repair procedures might require more specialized service information or professional assistance. Its purpose is solely for part identification.
