You are going to need a serial number to get the correct free manual but here's the link to the Lawnboy website....you have 3 choices based on the serial number
Open the link ...enter your model number, put in any serial number from the ranges indicated and click on the english manual....for a 1994 lawnboy. Oops ...it will only give you a parts manual or a non english operator manual. My mistake. Sorry.
The following link to another mower website may help you. There are 2 screens full of different lawnboy mower manuals including Duraforce
