067-8090-00 Mower Hydraulic Reservoir Tank Compatible with Bad Boy CZT/ZT Elite and Maverick Mower Fluid Expansion Tank Replacement ZT2-60 KW Fab ZT2-50 KW Fab ZT2-54 KW Fab ZTX4-48 KH Fab

What It Is

This is a replacement hydraulic reservoir tank (part 067-8090-00) for Bad Boy CZT, ZT Elite, and Maverick zero-turn mowers. It stores and supplies hydraulic fluid to the mower’s drive system; when the original tank cracks or leaks, this part restores proper fluid levels and prevents overheating or pump damage.

Fitment & Compatibility

• Exact fit for: Bad Boy CZT/ZT Elite models with 48, 50, 54, and 60-inch decks, plus Maverick models with 48, 54, and 60-inch decks. Also fits ZT2-60 KW Fab, ZT2-50 KW Fab, ZT2-54 KW Fab, and ZTX4-48 KH Fab.
• OEM equivalent: Replaces OEM part numbers 067-8090-00 and 067809000. It is an aftermarket part, not Bad Boy branded.
• Check before buying: Measure your original tank’s mounting bracket spacing (center-to-center of bolt holes) and the tank’s overall height. This tank is designed for side-mount brackets; if your mower uses a top-mount or strap-style tank, it won’t fit. Also verify your deck size and model year—older CZT models (pre-2010) may use a different tank shape.
• Fluid capacity: ~1.5 quarts. Confirm your system’s recommended fluid type (typically 20W-50 or 10W-30 hydraulic oil) and capacity.

Key Things to Know

• Quality: Made from high-density polyethylene (HDPE) — durable against UV and impacts, but not as thick as OEM tanks. Inspect for flash or thin spots around the fill neck before installing.
• Installation difficulty: Moderate (2/5). You’ll need to drain hydraulic fluid, disconnect hoses (use hose clamp pliers), unbolt the old tank, and transfer the cap and fittings. Expect 30–60 minutes.
• Common gotchas: The cap and dipstick from your old tank may not seal perfectly—use the included cap if provided. Also, the tank’s mounting ears can be slightly off; you may need to enlarge bolt holes with a file. Always prime the hydraulic pump after installation (crank engine, engage PTO, and cycle the drives slowly to purge air).
• Warranty: Typically 30-day return window; no manufacturer warranty. Check seller’s return policy.

Should You Buy It

If your Bad Boy CZT, ZT Elite, or Maverick has a cracked or leaking hydraulic reservoir, and you’re comfortable with a basic DIY swap, this $16.99 aftermarket tank is a solid budget fix. It’s not as heavy-duty as OEM, but for the price it works reliably for most homeowners and light commercial use. Skip it if you have a pre-2010 model or require a thicker, OEM-only part.
