Mighty Max Battery ML-U1 200CCA Battery for Toro Time Cutter SS5060 Zero-Turn Lawn Mower

What It Is

The Mighty Max Battery ML-U1 is a 12V, 200 Cold Cranking Amps (CCA) replacement battery designed for zero-turn mowers like the Toro Time Cutter SS5060. It powers the starter and electrical system, replacing a dead or weak OEM battery.

Fitment & Compatibility

Before buying, confirm:

• Dimensions: 7.68" L x 5.16" W x 6.14" H – fits the SS5060 battery tray, but measure your existing battery to be sure.
• Terminal layout: U1 group size with standard SAE posts (positive left, negative right when facing terminals). Check your cable orientation.
• OEM part: Replaces Toro OEM battery (part #121-7170). Mighty Max is an aftermarket brand, not Toro-branded.
• Model check: Designed for Toro Time Cutter SS5060 (deck sizes 50" or 60"). Also fits many other zero-turn mowers with U1 battery trays (e.g., some Husqvarna, Craftsman, Troy-Bilt) – verify your model.

Key Things to Know

• Quality: 200 CCA is sufficient for the Toro SS5060’s single-cylinder or V-twin engine (stock is often 180-220 CCA). Good for moderate climates; may struggle in extreme cold.
• Installation: Simple swap – disconnect negative terminal first, then positive, remove hold-down, replace, reconnect positive then negative. No special tools needed.
• Common gotchas: Terminal posts are slightly shorter than some OEM batteries – your cables may need slight adjustment or a terminal shim. Check hold-down bracket alignment; it may not fit perfectly.
• Life expectancy: Typically 2-4 years depending on usage and charging habits. Keep terminals clean and charge after long storage.

Should You Buy It

Buy this if you need a budget-friendly, drop-in replacement for your Toro Time Cutter SS5060’s dead battery and are comfortable with a basic DIY swap. Avoid it if you live in a very cold climate (need higher CCA) or want a sealed AGM battery for vibration resistance – this is a flooded lead-acid unit.
