Question about Garden
The blade on my bosch rotak 43 lawn mower is bent and blunted and I would like to replace it. It appears to be held on with a single bolt. I tried undoing this bolt with a wrench but it wont move at all. Is there a trick to removing the blade?
Follow directions. See if this works;
Warning! Switch off, remove the isolator
key, battery and grassbox before adjusting
Always wear gardening gloves when handling
or working near the sharp blades.
Turn the machine on its right side and inspect
the blade; if blunt or damaged, replace.
Use the following procedure to remove and replace
Insert a screwdriver into hole 26 to lock the
drive. Hold the blade 30 using gardening gloves
(not provided) and use a spanner (not provided)
to remove the blade bolt 29, blade washer 28
and blade 30.
Fit the blade 30, blade washer 28 and the blade
bolt 29. Ensure that the blade is the correct way
up (so that this symbol can be seen located
as in figure I) and tighten the bolt 29 firmly.
Ensure the screwdriver is removed before attempting
to turn the machine on.
If this procedure does not work then try the following;
It is not uncommon for the blade bolt to become seized onto the shaft due to all the gunk and moisture on the underside of the deck. Try to soak the bolt several times over with penetrating oil ( WD 40, PB Blaster, etc). Spray the bolt head, the top of the blade where it contacts the shaft, etc. Do this several times and let the penetrating oil soak in. Hit the bolt head gently several times with a hammer to loosen up the corrosion. Then try to remove the bolt per directions.
Hope this helps, if so Please rate, Thanks, and Good Luck!
