40c 6v-12v

I have a 53 40c, my experience with it at 6v is all positive and my experience with using 12v without changing the starter to 12v is all negative, My opinion is fix the 6 v generator, as previous poster stated, not likely too much involved to fix it my 2 cents

zerks vs button heads

To eliminate dirt problems if a zerk breaks, use one zerk and install hex head plugs, then use the one zerk and remove the plugs when greasing, takes a little longer and time is money if you are working by the hr, but for hobbyist???

MC winch

as Lavoy says I have a Ramsey winch mounted on my 40c and chain driven from pto, very strong , just have to make your own mounting brackets, I welded a big nut unto the drive sprocket so that in a pinch it could be turned backwards

40c hydraulic

my 40c has a float option, it is explained how to enable it in the manual. at least in my manual. There is a hex cap on side of control valve and if I remember rightly you take it off and tske the plunger out and reverse it for float?? Going from memory not manual. Try it.

polarizing generator

I too have a 6v new gen from this site that wont charge unless it is polarized, I have taken it apart and ensured the brushes were well seated and cleaned and tightened all electrical connections and now have a pushbutton across the cutout to give it a shot to start it generating???
