You stated the TimeMaster was a homeowner model. I'm guessing, you think that because Toro has it listed in their homeowner section. What I wanted for you to do is actually investigate the three available 30" mowers. I wanted you to read the 30" threads and find the facts. The reality is all three mowers are homeowner models. The two "commercial" options are just tarted up homeowner models. One has more HP, while the other has more torque. They both have transmission/drive issues. They have different controls. They all have sealed bearing wheels, though, the eXmark has a little more aggressive tread on the tires. The height adjusters are different, but, the TimeMaster seems more convenient. They both have the same deck (I currently have an eXmark baffle bolted in my TimeMaster). The commercial versions have bigger fuel tanks, canister filters, and supposedly more durable engines. There's a 35lb difference, too. One owner, who owns both machines, actually prefers the TimeMaster over the other two. But, overall, preference seems to be influenced by what features one desires. The bottom line is there are no true commercial 30" mowers that have the durability and reliability of, either, your WB or Honda. Toro/eXmark can label the 30" machines however they want, but, none are really commercial quality.
