You can get a chute to attach to victa mowers to make them a side thrower, they are not that expensive,,,,
Do not cut or weld the blade disc, there are 4 blade discs available, cytting and welding wiull weaken it and you do not want it to fail at 3500rpm..

Good point about not wanting it to come apart but I doubt if decent welding would weaken it. I will investigate the 4 blade disc from Victa though thanks.
