GY21106 Pto Control Cable for John Deere 100, L100, L110, L111, LA105, LA120 Series Riding Mowers Parts, Replaces John Deere GY21106, GY20156

What It Is

The GY21106 PTO control cable engages and disengages the mower deck’s electric clutch on select John Deere 100 Series and LA Series riding mowers. It’s a direct replacement for a worn or broken cable that won’t pull or release the PTO switch.

Fitment & Compatibility

This cable fits John Deere models: 100, L100, L110, L111, LA105, and LA120. It replaces OEM part numbers GY21106 and GY20156. Before buying, measure your existing cable’s total length (including ends) – it should be approximately 42-44 inches. Check that your mower uses a push-pull PTO engagement (not a lever-style or electric switch). Verify deck size doesn’t matter – this cable is for the dash control, not the deck itself. If your mower has a GY20156 cable currently, this will swap directly.

Key Things to Know

• Quality: Aftermarket cable; reviews note it works well but plastic end fittings may feel less durable than OEM. Lubricate the cable core with light oil before installation to reduce stiffness.
• Installation difficulty: Moderate. You’ll need to remove the dash panel and possibly the battery tray on some models. Allow 30-60 minutes. A small flathead screwdriver helps release the cable from the PTO switch.
• Common gotcha: The cable housing is slightly longer than OEM on some units – you may need to zip-tie excess slack near the clutch or bracket to prevent rubbing against the engine or frame.
• Fitment nuance: Won’t work on L120 or LA130/LA140 models without verifying cable length – those often use a different routing.

Should You Buy It

Buy this if your John Deere 100/LA100 series PTO cable is stretched, kinked, or snapped and you want a budget fix. It’s fine for homeowners who don’t mind basic hand tools and a little patience. Skip it if you need a heavy-duty cable for commercial use or if your model isn’t listed – you’ll likely want OEM for guaranteed fit and longer life.
