    I'm trying to figure out the costs that I incurr while mowing. My main unit is a 21" Exmark with the Kawasaki engine and a I have an 06 commercial Lawnboy. Does anyone know the amount of hours each unit should last? My guess is about 1 000. Is that correct or not? Thanks

    I have Honda HRC 216's 21"s that are 7+ yrs old. Well over 1000 hrs I suspect.

    "Lifespan" to too ambigous of a measure. The question is rather when do you stop putting money into repairs and/or replacement parts. The mowing deck may last a very long time, many thousands of hours. But, the engine may not last that long, so you may wish to repower with a new engine, or put a short-block on the old one. Transmissions may show signs of wear and need parts to be replaced. Drive cables, wheels, height adjustment levers, ... (the list goes on, on).

    I have an old model LawnBoy. The deck has probably seen well over 2,000 service hours. But, it has been short-blocked, many sets of replacement wheels, many ground drive cables, transmission bushing changes, pinion gear replacement, rebuild of the rear wheel drive assembly (keyed gear). I keep it as a spare. We used it all day recently when the ignition module failed on my newer LawnBoy (Duraforce engine).

    My point is there is no definition of "lifespan," only when you choose not to do more replacements and repairs.

    My dura force 6.5 2-stroke lawnboy went 700hrs before it needed major repairs. I use it ruthlessly, but very carefully. Never go into tall grass without having been there before etc. I clean it every few days, and always did general maint. weekly. It still looks like new. :weightlifter:

    I used to have only toros, they went about 500hrs before they needed major repairs. No matter how I cleaned and maint. them they always looked tired and beat.

    i have (2) commercial lawnboys that are on their 8th year, used all day, every day (march-mid december)
    original engines, decks. some repairs occasionally, but never anything major.

    i have no experience with the new 4 stroke though... other then they bolt right on my decks when i need them down the road.... some day:weightlifter:

    I used to have an old Honda HR214 that was 20 years old when I got rid of it. The engine smoked a little at startup, but it did the job it was designed for.
