Honda HRX timing belt issues?

    I have been using hrx lawn mowers for most of 10 years now, no serious issues, normal maintenance. I run them to 6-700 hours and sell them and replace. Last fall when preparing my mower for storage, oil change and cleanup, I hit an issue. After finishing up I decided to stat the engine one last time. Engine started for maybe 2 seconds then I could not restart. Checked everything I could think of and found nothing. So I take it to the dealer. Im told the timing belt needs to be replaced.... at a cost of +$350. estimated. Wow this engine has only 140 hours on it. (I put hour meters on all my gear) This is virtually a new mower. I have yet to get the mower back so Im not sure of the exact cost of this repair. Is anyone else having trouble with honda timing belts? I really like honda mowers on my 6th HRX but this may move me to change over to another brand.

    Where is the timing belt? the only belt I see is the one that is above the blades, and is turned by the mower engine and goes to the transmission.
    I could never get transmissions on these to last much more than a year and the dealer wanted about $350 to replace the trans. ( I do not know why font has changed either)

    Sounds like a new engine price not a repair price.

    I think what happened is it came off at the top. The engine didnt really start. It fired a couple times and quit. Seems it fired as the belt was rolling off. Had it broke while running it probably would not be repairable.

    Trannys have never been an issue. I change the oil in them at about 300 hours.

    Mower is back from the dealer. Replaced timing belt $357. Nasty. Apparently due to the design the engine it has to be removed and tore down to replaced the belt and re time. about 5 hrs labor so im told. Had the mower been any older a repair would not have made any sense at all. Hopefully I get another 600+ hours from the mower.
