I haven't seen that brand in the USA.

Thanks Tomplum, I've searched around the machine including jacking it up and going underneaththe rear, and I cannot find a lever. Thanks also Ggoyeneche, that is a good logical suggestion. I will search further although I'm struggling to picture exactly where you mean. Much of the drive mechanism which contains belts and a chain is shielded by body-work. I imagine that is deliberate to keep grass and sticks away from the drive and blade belts. Purely as a matter of interest, I also have a 16yr old Viking (Stihl) rider which is manually geared and side discharge only. It is a dream to work on compared to this rear-discharge hydro Castelgarden. Everything on the Viking is open and easy to see - and reach. I bought the hydro from a friend because of its grass-catcher. Frankly its been more trouble than its worth but in fairness thats probabably because my friend didn't look after it. Interesting learning curve...

g'day tony, the best self propelled mower is the snapper mate for me nothing comes near them. yes apparently b&s getting a bad name but me i'm usually wary of bad hype as lots comes from lack of understanding by the regular user. i had the b&s on my greenfield shredder it worked just as well as the 20+ year old motor on my mower but then after years of fixing mowers i do give them good servicing oil is cheaper than motors. masport of course are new zealand mowers. the honda motor is getting good market share most professionals use honda motors. and of course victa no longer aussie owned sunbeam (usa) took them over when i was still repairing mowers over 20 years agao and i saw of late that sunbeam has been taken over by someone else. as far as i know rover and greenfield are true aussie machines but they don't use aussie motors there just isn't one good enough that was ever made here, they use b&s and honda at the very least. and the demise of the 2 stroke motor is well under way as per EPA regulations rules and sunbeam/victa knew all this when i was still repairing mowers so it is nothing new in the usa their home grown 2 stroke mower manufacturer has stopped production of its 2 strokes. len

Looks like a stryping (striping) Mower. Popular in the UK not in the USA. Although all the professional baseball game stadiums strype the fields. Honda and Harrier Hayter make them. I have a Hayter 22 inch and it does a great job of striping. I modified mine to cut higher.
