Which 21" mower completes small residentials the quickest?

Of the Honda hydrostatic commericial, toro commercial proline, Lawnboy commericial or john deere JX 85, which unit seems to travel the fastest and complete small residential places the quickest?

Thanks.

 

I prefer a snapper with a 6 horse, it's fast and has a very large discharge chute, it clumps very little if you cut the chute in half. Not recommended from a liability/manufacturer standpoint, but functions well.

 

The metro 21 I just bought the other day sure does make quick work of small lawns.

 

Thanks for the information fellows. I appreciate it. Looks like the toro wins.
