We have varous mowers including an older hayter 56 wide bag (roller), hayter harrier 41(roller), Toro 21 heavy duty, Husqavana mulcher, Kaas Danarm 19" (roller) and some other rough cut mowers.
I find none of them are great at this time of year with damp grass, especially in the morning with heavy dew.
I've looked in the archives here and Etesia have been mentioned several times for being good in the wet, and others have started to mention the new Weibang roller machines, plus Viking gets a rare nod.
Ideally 20" plus, self propelled, roller is a bonus, or at least a rear skirt. Must have robust body parts and engine.
So what do people find as the best commercial damp mower.
