That is not overworking a Victa 2 stroke, they are easily capable of that work, be a bit better if it had the fan shroud to get some cooling over the motor. Also the motor does not have a lot of compression because as you can see when starting it shows little resistance on when he pulls on it without a decomp valve in it. The other thing that will kill it is the use of a pod filter down there, they are only good for keeping out rocks and quails. Another thing that makes it a lot easier on the motor when chewing through that sort of grass is having the rear flap lifted a bit so the grass can be ejected out, not getting bound up inside the mower. Then the will really get through that stuff easily
