Barrie, that post was a bit tongue in cheek to be honest, seen so many people complaining about this problem on the new Hayter Harrier's. Thought I'd just show that's it's not unique to one machine.
I've always said, cutting in the wet, or even really damp conditions will always be a compromise. "Lawn" Mowers are not designed to cut in the wet. Seems a fairly new craze these days, complaining about the machine not handling wet conditions. It's pretty obvious some can work better than others in these conditions, more by luck than by design methinks, though they won't admit this.
I don't think it's fair to complain to the manufacturers when things clog up, when the machine is being used incorrectly. That said, the Harrier has had some clogging / collecting issues which Hayter are working very hard to resolve.
Double whammy here is the Pro's want to cut in the wet, and then they say that the machine is too slow, so the manufacturers listen and the machines get faster. Something has to give.
As for customers sending machines in for servicing in a right state, yes I'm in total agreement with you. We turn up to collect Ride on machines and the customer hasn't even bothered to empty the grass box, the machine has been put away like that. Mower deck when you take it off you can hardly lift due to the weight of all the crud underneath. Then they question why the deck rotted through. Some even bring their mowers in with full grassboxes, which we politely hand back to them. I don't know what they expect us to do with all that stuff tbh, It costs us money to get rid of it.
