Key Components of the John Deere 737 Zero Turn Deck
The deck assembly consists of several crucial components working together to deliver a clean cut. Let's break down some key areas:
1. Blades:
These are the cutting tools of the mower. Regular sharpening or replacement is vital for optimal cutting performance and preventing damage to the deck. Different blade designs are available, each suited to specific grass types and conditions. Check your owner's manual for recommended blade types for your 737.
2. Spindles:
Spindles are the rotating shafts that hold the blades. They are subjected to significant stress and require proper lubrication and occasional replacement if worn or damaged. Inspect spindles for wear and tear during regular maintenance checks.
3. Belt(s):
The belt(s) transfer power from the engine to the blades. A worn or broken belt will prevent the blades from rotating. Regular inspection for wear and fraying is crucial. Knowing the type and size of belt needed is essential when replacing.
4. Pulleys:
Pulleys work in conjunction with the belt(s) to transmit power. They should be inspected for wear and alignment. Misalignment can cause premature belt wear.
5. Deck Housing:
The deck housing protects the internal components and directs airflow. Check for damage such as dents or cracks.
6. Idler Pulleys:
These pulleys control the tension of the belt(s). Ensure they are properly adjusted and free from damage.
7. Deck Height Adjustment:
The 737 typically has a deck height adjustment mechanism. Understanding how to use this mechanism is crucial for setting the correct cutting height for your lawn conditions.
8. Anti-Scalping Wheels:
These small wheels prevent the deck from digging into the ground, especially on uneven terrain. They should be checked for wear and proper inflation.
