Got 1 in my service run.
Owner is on 10 acres of very hilly ground.
He has it serviced every year without any problems. Nothing has needed to be done other than scheduled service items.
It is fitted with a 48" pressed deck and he is now running Gator blades and throwing the clippings
He is very happy with it.
My only problem is the rear steel guard is very close to the engine and needs to be removed to check the valve lash.
And the oil filter is impossible to pull off clean apart from that it is a pleasure to work on.
All bolts are either 10mm or 12mm and JD provide a 12mm spannar in the height adjustment pin with has a keyhole pinch in it so it does not fall out.
The "edge" series decks were prone to cracking around the deck hangers but his has been fine.
I have 3 customers with the smaller Z225 fitted with 18Hp inteks.
Again none of them has given any problems except for the 1 which was used commercially where the lifting arm on the deck lift rod cracked through and needed to be welded .
All of these customers are very happy with their mowers.
Down here we get a McCulloch & Craftsman which are so close to being identical they would have to be coming out of the same factory.
They are both fitted with the AYP decks and give no end of grief, eat spindle housings, crack decks & drive like a drunk shopping trolley but they are 2/3 the JD price and you only get what you pay for.
