Compatibility
Fits Toro 51870 Polesaw as a direct replacement for the factory chain. Always confirm your saw’s model number and bar length before ordering to ensure proper fit.
Installation notes
Before installing, retract the pole saw to a manageable length and disconnect the power source. Loosen the bar-mounting nuts or knob, remove the side cover, and slide the old chain off the bar. Seat the new chain around the bar nose and into the guide groove, making sure the cutting teeth face forward on the top of the bar. Reinstall the cover and adjust tension until the chain is snug but can still be pulled around the bar by hand.
Common questions
Q: Will this 2-pack 10-inch pole saw chain fit my Toro 51870 pole saw, or do I need to match anything else besides the bar length?
Yes, this chain is made for the Toro 51870 polesaw with a 10-inch bar, so it’s the correct replacement for that model. It’s still a good idea to confirm your saw is using the original 10-inch setup and compare the old chain before installation if your bar or chain has been changed previously.
Q: How do I know if this 10-inch chain needs to be replaced on my Toro 51870 instead of just sharpened?
If the chain is cutting slowly after sharpening, pulling to one side, or has damaged, cracked, or missing cutters, it’s time to replace it. A stretched chain that won’t hold proper tension well on the Toro 51870 is also a strong sign replacement is the better option.
Q: Any tips for installing and maintaining these replacement chains on a Toro 51870 polesaw?
When installing, make sure the cutting edges on the top of the bar face forward in the direction of chain travel, then set the tension so the chain is snug but still pulls around the bar by hand. Keep the chain lubricated, check tension frequently during the first few cuts, and clean debris from the bar groove to help the new chain last longer.
