Re: Help me choose
How is your property? Relatively flat?
The K46 is a fine lawn tractor transaxle, but it's biggest weakness is heat. Always run wide-open throttle when operating the lawn tractor, that keeps the cooling fan going faster. Keep debris cleared off the transaxle, that will help with airflow. You can do some towing with them, but use common sense. Don't be afraid to make more, smaller, trips. The K46 is also fine for pushing a snowblower, as it doesn't stress the transaxle- but on the same note I wouldn't plow snow with one.
The problem with the K46 is that while the oil can (and should) be changed, they're pushed as non-servicable, so people don't bother with it. Well, as the trasnaxle heats up the oil breaks down, and it just goes from there.
So, in short, the K46 works fine for most residential mowing.
Got hills? More than two acres? Or you know you have a history of pushing your equipment? Go for a garden tractor. You'll never regret buying more machine than you think you'll need.
