I've used the HRT216 for 4 years now but the engine does not go to full throttle anymore I am looking into purchasing a new small mower which would only be used on 3-5 lawns per week. Has anyone used the metro 26" it looks like it could save some time yet get through all the small gates. Also I hear some people talking about toro proline 6.5 HP but the toro website only shows a 6 hp max. and the metro is only 25 lbs heavier. How about the durability differences between these machines?
