Ok, since the grass has been so tall lately, it has forced me to double cut because my catcher sucks. My question is, since I have an older model 1996 SWZ 52", my mower came with a 14hp Kaw. Now I want to do doubles but I don't know if this engine will turn them fast enough because there would probably be a chance that the spindle would break. Do you think it would be ok to run doubles even though i'm running this small of an engine on this large mower. I also have added weights on the front to keep the deck from bouncing; do you suggest I take these off so that the mower is lighter and I can save more power for the blades?
