This zero-turn mower is known for its efficiency and performance, but I quickly realized that understanding the deck was crucial for getting the most out of my investment. Here’s my comprehensive buying guide to help you navigate your options for the Cub Cadet RZT 50 deck.
Understanding the Deck Size and Design
The first thing I considered was the deck size. The RZT 50 features a 50-inch cutting deck, which strikes the perfect balance between maneuverability and cutting efficiency. This size allows me to cover more ground without sacrificing control, especially in tight spaces. I recommend measuring my yard to ensure this size fits your needs.

I’ve experienced less wear and tear over time, which means fewer repairs and a longer lifespan for my mower. It’s essential to choose a deck that can withstand the elements and the rigors of mowing.
Cutting Height Adjustability
One feature that I absolutely love is the cutting height adjustability. The RZT 50 deck allows me to easily adjust the cutting height from 1.5 to 4 inches. This flexibility is perfect for my lawn, as I can adapt to different grass types and seasonal changes. Make sure to check how easy it is to adjust the height on the model you’re considering.
Maintenance and Cleaning
I can’t stress enough how important it is to maintain the deck for optimal performance. The RZT 50 deck has a wash port, which makes cleaning a breeze. After mowing, I simply attach my hose to the port, and it cleans the underside of the deck. I highly recommend looking for this feature, as it helps prevent grass buildup and rust.
Blades and Cutting Performance
When I first used the Cub Cadet RZT 50, I was impressed by the cutting performance. It comes equipped with high-lift blades designed for superior grass cutting and bagging. I’ve noticed cleaner cuts and healthier grass. Before buying, I suggest checking the type of blades included and considering whether you might want to upgrade for specific needs, like mulching or bagging.
Compatibility and Replacement Parts
If you’re like me and want to ensure longevity, consider the availability of replacement parts. I found that Cub Cadet has a good reputation for offering compatible parts, which makes maintenance easier. Always verify that the parts you might need down the line are readily available.

Finally, I looked at the price and warranty options. The Cub Cadet RZT 50 deck is a bit of an investment, but I believe it’s worth every penny for the quality and performance it offers. Additionally, I was pleased to find that it comes with a limited warranty, which gives me peace of mind. I recommend checking the warranty terms to understand what is covered.
