Hello all! I have owned the Honda HRC216HXA commercial mower for 2 years now and swear it is one of the sweetest mowers I've used to date. Recently I bought a new Toro commercial with the new Kawi KAI engine. The new engine was redesigned to address issues that arose with the original FJ180V. This new mower is pretty sweet but I will concentrate on engines only since you can buy the toro with either and I am almost positive that honda quit making commercial 21's. Honda: Mechanical > extremely well made, I've been around full blown pro mod engines for some time and for this engine to impress me says a lot! >air cleaner...small part but absolutely essential to engine performance and longevity. They didn't take "dual element" lightly at honda with both parts designed for maximum efficiency in both air flow and extent of clean air. >No oil filter but if you are serious about your equipment running for season after season you will change the oil before filtration becomes an issue ;-) >The engine itself is cleaner. I have 2 full seasons on the honda and the engine itself still looks new, with absolutely no grease or oil buildup! The engine runs like a champ starting on the first pull requiring 2 pulls only in the winter time...and even then it starts on the first pull 99.9% of the time. It has a completely different sound from most other mowers, being quieter and...forgive me but I must...better made =) I know I know that sounds stupid but...this whole comparison is objective so why the heck not! I can honestly say that I can see this engine lasting as long as my beloved toro 2 cycle...and that says a lot! Kawi >Air cleaner is "dual element" but they went with the cheap stuff with the outer element being tissue paper thin, not oiled and the paper filter being pretty weak too. It still does the job, but considering its competition its pretty flimsy. >Has oil filter like previous Kawi FJ180V engine. I change the oil before it ever needs filtration like every other crew I know. But if it stops one detrimental piece of debris then it was worth it! ;-) >Louder than honda engine >Already had mechanical issues with the carb. The week that I bought it...it started stalling. I took it to the mechanic who by the way put more scratches on my machine then the most careless crew...it was warranty work but now the engine smokes. You can't see the smoke with your eyes but I coat the muffler with WD-40 to prevent rust and I always wipe carbon build up off after each use. The dealer says that is normal. I say he is full of SHI...quiet thoughts... >Power...this thing is a beast! My honda has balls...but not like this! Last week I took a one hitter against my best judgment. It hadn't been mowed in at least a month and the grass was maybe 8 inches tall or taller. The Kawi only bogged twice but never died. My honda would of died every 10 feet! Kudos to the power dept. >Kawi is already dirty where trace amounts of oil collect dirt at the main engine gasket. I know it's a lawn mower...but the honda has it beat there. Clean equipment gets compliments and makes you look more professional against a crew that uses red equipment...at least you know in the beginning it was red but now it looks like they pulled it out of a fire or something. Overall I would say hands down if you are in the market for a commercial 21 go with the honda engine. I have yet to have the dealer up the rpms on my honda so I really don't know what I'm missing. Everyone here goes ape poop for the suzuki 2 cycle and I know why. In 10 years the honda engine will earn that kind of respect too because each one is consistently made with quality being #1 on the list of priority. The kawi is cheaper but I just bought a brand friggin new one and I already see the superiority of honda engineering. Right on!
