How do you fit a drive belt to bosch rotak 34 rotary mower please?

Answer 1

Firstly, make sure the power is disconnected. Remove the blades. Remove the 4 screws on the underside of the mower that are behind the blades (they might take some locating if they are coated in grass, just scratch the grass off until you find all 4). Now pull the motor out of the mower. Both of the belt wheels should come off.

Now boil a load of water. Find a bowl large enough to totally submerge the belt in water. Using some of the water from the kettle, submerge the belt in boiling water. Use the remaining water to make a cup of tea.

Make sure both belt wheels are in position as you won't be taking them off again (also make sure the weird chalk block thing is still behind the larger wheel).

Let the belt sit in the hot water for a minute or two and then remove it with a screwdriver. Put the belt fully on the small, grooved wheel and as far around the large wheel as you can. Use the screwdriver to lever the belt around the rest of the large wheel and slide it down using the end of the screwdriver until you are happy that it is in place. Now just put everything back together and enjoy your cuppa.

you don't. I've just thrown mine in the bin. The belt goes on so tight, I couldn't get the new one on
