Flat Idler Pulley Replace 07351200 Compatible with Ariens 60 52 Apex 60 52 48 / Gravely ZT HD Z-Stance Pro-Walk Pro-Turn Pro-Stance Compact-Pro, 5" x 0.75"

What It Is

This is a replacement flat idler pulley (5" diameter, 0.75" wide) that routes and tensions the deck belt on select Ariens and Gravely zero-turn mowers. It’s designed for decks on models like the Ariens Apex 60/52/48 and Gravely ZT HD, Z-Stance, Pro-Walk, Pro-Turn, Pro-Stance, and Compact-Pro.

Fitment & Compatibility

Before buying, confirm your mower has a 5" x 0.75" pulley and uses a flat (not grooved) idler. This part replaces OEM number 07351200 and fits Ariens and Gravely decks in 48", 52", and 60" widths. Double-check your model and serial number against the OEM spec—some Pro-Turn and ZT HD variants may use a different bearing or offset. Measure your existing pulley’s center hole diameter (typically 5/8" or 3/4") and bolt pattern if applicable; this pulley uses a single center bolt. Not for stamped-steel decks or older Craftsman/MTD decks.

Key Things to Know

• Quality: Aftermarket steel pulley with sealed bearings—comparable to OEM, but check bearing smoothness before install (spin by hand).
• Installation: Easy swap—remove deck belt, unbolt old pulley, bolt on new one (typically 9/16" or 5/8" socket). Torque to 20-25 ft-lbs; overtightening can warp the pulley.
• Gotcha: The 0.75" width is critical—if your belt is 1/2" or 5/8", this pulley may not align. Verify belt width on your deck diagram.
• Common issue: Worn bearings cause belt squeal or wobble; replace in pairs if both idlers are worn.

Should You Buy It

Buy this if you need a direct-fit, budget-friendly replacement for a worn or noisy idler pulley on a compatible Ariens or Gravely zero-turn—just verify your deck size and belt width first. At $27.99 with strong reviews, it’s a solid value for DIY maintenance.
