1. 951-12428 Fuel Gas Cap with Tether, 2.25" Vented, Compatible with MTD Cub Cadet, Troy-Bilt, Craftsman, Murray Zero Turn Mowers
This replacement earns its ranking by being the ultimate low-cost insurance policy for your fuel system. A cracked or missing cap lets debris enter your tank, which can cause significant engine trouble later on.
In my view, this is the most practical item for any owner to keep on a shelf. It fits a wide range of models, providing a secure seal that keeps your fuel clean. Just be aware that the plastic tether is a basic component, so avoid yanking it too hard during refueling.
Owners consistently appreciate that this part matches the original equipment specifications.
The vented design is critical for preventing vacuum locks in your fuel line.
Buyers note this is a simple, plug-and-play solution for lost caps.

2. 42" Deck Spindle Belt 2135600002A Fit for Murray Cruz 42 MYZ4219000
This belt is the perfect match for the DIY owner who wants to handle deck maintenance without a professional mechanic. If your mower has stopped throwing clippings correctly or the blades feel sluggish, replacing a stretched belt is usually the first fix you should attempt.
I consider this an essential item to have in your garage before the season begins. It provides the proper tension required for a clean cut, though you should verify your specific model number twice before ordering. Installation can be a tight squeeze, so having a basic set of tools ready is wise.
Users report this belt restores the power transfer needed for consistent blade speed.
The reinforced construction is intended to hold up against the heat of summer operation.
Most buyers find the fit is accurate for the specified Murray Cruz series.

3. Greenworks 60V 42" CrossoverZ Zero Turn Mower, (6) 8.0Ah Batts&600W Chgr
The most unexpected feature here is the integrated battery management system that allows you to swap batteries between your mower and other outdoor tools. Moving away from gas power means you no longer have to store volatile fuel or worry about carburetor gumming during the off-season.
In my judgment, this is the superior choice if you are tired of internal combustion maintenance. It delivers instant torque and a remarkably quiet operation that won't wake the neighborhood. You must check that your property size is within the range of these batteries, as total runtime is the only real constraint you will face.
Buyers appreciate the lack of oil changes and filter replacements compared to gas mowers.
The dual-motor system provides enough power to handle hills and thick grass.
Many users highlight the convenience of the included rapid charging system.

Choosing Between Them
I recommend the Greenworks 60V CrossoverZ as the best path forward for anyone seeking a full machine replacement. It is the most forward-thinking option, pairing perfectly with homeowners who want quiet, battery-operated efficiency. If you are simply looking to maintain your existing fleet, the Murray Gas Cap and Deck Spindle Belt are the high-value, essential parts that will keep your current mower running smoothly.
Before you invest in the Greenworks model, ensure your property size aligns with the total battery runtime to avoid mid-mow delays. While these components and machines are reliable, always double-check your specific model numbers against the compatibility charts to ensure you receive the exact fit for your gear.
