440934 532440934 Lawn Mower Zone Control Cable for Murray Lawn Mower Craftsman Engine Poulan PO500S PO550R PO550S PO550SH PR450 PR550 PR550H

What It Is

This zone control cable (part 440934 / 532440934) connects the control handle to the mower deck’s engagement mechanism, allowing you to start and stop the blades from the operator position. It’s designed specifically for Murray, Craftsman, and Poulan walk-behind mowers with engines like the PO500S, PO550R, PO550S, PO550SH, PR450, PR550, and PR550H.

Fitment & Compatibility

Before buying, check these three things:

• Model number, not just brand: This cable fits specific Murray, Craftsman, and Poulan models (e.g., PO550S, PR550H). Look for a model tag under the seat or on the frame—don’t rely on the engine brand alone.
• Deck size: Works with 42-inch to 54-inch cutting decks, but measure the cable route on your mower. The cable is roughly 60 inches long (housing + inner wire). If your deck is larger or the routing is indirect, it may be too short.
• OEM vs. aftermarket: This is an OEM replacement part (Craftsman/MTD), not a generic. It matches the original fit, so no adapters or modifications needed if your mower is listed.

Key Things to Know

• Quality: Durable steel inner cable with a corrosion-resistant coating. Housing is reinforced plastic—holds up to normal use but can kink if bent sharply during installation.
• Installation difficulty: Moderate. You’ll need a 3/8-inch wrench and pliers. Takes about 20-30 minutes. The trickiest part is routing the cable without pinching it against the frame.
• Common gotchas: The cable ends are pre-swaged (no adjustment barrel). If your old cable had an adjustable barrel, you may need to buy a separate adjustment kit. Also, check that the mounting bracket on your deck isn’t bent—if it is, the cable won’t engage fully.
• Fitment check: If your mower has a “zone control” system (two levers for blade and drive), this is the blade cable only. It will not work for drive control cables.

Should You Buy It

If you have a compatible Murray, Craftsman, or Poulan mower with a faulty blade engagement cable, this is a direct fit at a fair price. The high rating (4.6 stars, 1,875 reviews) reflects consistent reliability. Skip it if your mower isn’t on the fitment list or if you need an adjustable cable—this one is fixed length. For the money, it’s a solid OEM replacement that avoids the guesswork of generic cables.
