Can anyone tell me how to remove the cutter blades for this mower.  I cannot remove the cutter chain wheel assembly that has two bolts (set pins) underneath that I need to remove in order to remove the cutter blades.  Any assistance is appreciated.

Will help if you can be a bit more specific about the age of the machine  Atco have made a 14" machine from the year dot until present times! -an image could be useful. Can't immediately visualise your "boats". Never heard the term!

Sorry Wristpin, I misspelled "bolts". I tried to paste an image of the area that I'm trying to remove without any luck.  The model is B23 1967/8.  I don't know if the 1967/8 was the year this model was manufactured.

Also if you can direct me as to how I can include an image in the comment section of a forum message, please advise.

OK, think that I know what you have - let's hope that I've guessed correctly!.

The sprocket is screwed to the cylinder shaft with a left hand thread.

Remove the throw/deflector plate, two screws and pull it upward.

Jam the cylinder with a piece of wood and devise a way to grip the sprocket without damaging the teeth and turn it clockwise - it will probably be tight. You can use a chain wrench for that or if you have the facility a two foot length of steel bar drilled to take two 8mm bolts spaced to drop into the teeth 180 degrees apart.

With the  sprocket out of the way you will see the heads of three hex head set screws (bolts!) . There will be another three on the opposite side of the mower. Remove all six and the cutter unit will drop out with a bit of a wiggle. (On edit) it will come out easier if remove the front roller assy. And slacken the hex head screws holding thr engine mounting platform to the RH side plate and spring it slightly out wards - gives more wiggle room !

You will then have the cylinder in its bearing carriers fixed to the sole plate (bottom blade carrier) by two hex head screws at each end. These are likely to be tight/corroded so lots of releasing fluid such as Plus Gas and a moderated approach is the order of the day to avoid shearing them.If luck is against you the captive nuts that they screw into may come adrift and make life difficult - crossed fingers!

Earlier machines have Imperial (BSF/Whit) threads and spanner sizes; later ones UNF/AF

I'm a bit pushed for time this morning but will try and find some images and post later.
