I bought a set of Meg-Mo's to go with my new mower, a Redhawk 36" cut dual hydro. I got them a couple of weeks ago (which was ~3 weeks after I ordered them). When I tried to install them I found that my bolts would not fit through the hole, Roy offered to take them back and drill bigger holes but I found a metal worker friend to do it using an end mill. I typically need to cut every 3~4 days this time of the year but I've been very busy this spring and have been cutting every 6~7 days. So I've been cutting some heavy growth. With mower set at ~3-1/4" cut and I have been taking 3~4" off in many spots. The last time I cut was exactly 1 week ago. A great test for the Meg-Mos... I installed them last night and tried them today. First, with the regular high lift blades + side discharge shield on, I had been getting quite bit of clumping is spots cutting every 6~7 days. So off I go with the Meg-Mo's today... First, when the blades are engaged with the throttle low, there is a bit of a metal banging sound as the blades come up to speed (should I be concerned about this?), as the throttle is moved to high, the blades speed up and start making a helicopter/vacuum sound. The mower vibrates slightly more (vs High Lifts). I'm happy to report that with the Meg-Mo's there is virtually no clumping (just a little bit in the really heavy areas. With the discharge shield down, the clippings still disperse quite well (2~3 rows over). Overall a much cleaner cut with the Meg-Mo's. The grass was for the most part dry but high in moisture content as it rained quite a bit last night here. I did notice that some clippings were longer than what I've seen other members report (posted pics), but there were clippings left on the lawn from the last time I cut that I didn't completely disperse with the blower. I'm wondering if it's not these that the Meg-Mo's are throwing around... After I cut I jacked up the deck and checked it out. There was little/no build up under the deck. So overall, the first cut went well. Keep in mind that I'm a homeowner and I can cut pretty much under favorable conditions (not while it's raining or when the grass is excessively wet). For me the Meg-Mo's seem to be operating as advertised. The next several cuts should tell for sure.
