This is where I would like to see improvement on this mower. For what we do it is only barely adequate. We mow mostly flat smaller properties and the trans needs a push to get it moving. I believe there is a way toro/exmark can make a better trans and this would be a simple no brainer to buy mower. You can adjust the cable to help but is only a little help. None the less we will never go back to a 21, just doesn't make sense.
