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.
