Our bump feed nylon line cutter heads are very popular. Of course they come free with our brushcutters, but they also fit many other machines. The inner nut thread has a 1.25 pitch and comes in either 8mm, 10mm or 12mm. Part numbers 71037-182, 71037-181 and 71037-225 respectively.
For orders of 10 or more heads we can supply at reduced prices.
