What this is
Two replacement chains for Toro’s 60V 10” pole saw, the 51870 (kit) and 51870T (tool only). Toro’s operator’s manual and parts catalogue give the chain as 10”, 1/4” pitch, .050” gauge, 58 drive links, Toro part 88621. This pack is the same size.
Toro’s own pages disagree on pitch
Toro’s product page for the 51870 lists a 3/8” pitch. Its operator’s manual and parts catalogue both say 1/4” with 58 drive links. We follow the manual. A 3/8” chain for a 10” bar would have far fewer links — so if your old chain has 58 drive links, it is the 1/4” chain, and this is the right replacement.
Kobalt’s 80V KPS 1081-06 and KPS 2081-06 pole saws take a chain of the same size; see our Kobalt 80V pole saw chain.
Fitting it
The 51870 is tensioned with a chain tensioning screw, using the tool supplied with the saw. Toro’s manual gives the correct tension as being able to pull the chain 1/8 to 1/4 inch away from the bar.
