My Dad bought an AMF lawnmower in the 1960's, that has a small lever that raises and lowers the blade. It takes a whopping 2 seconds to change the blade height. Yet I can't seem to find this technology in any of the new lawnmowers. Does anyone know of a push mower that can quickly change cutting height?
Hi K,
What you describe is exactly how my nearly 30 year old LawnBoy self propelled mower works. There is a lever on the rear frame of it that adjusts the blade height. It also has 6 adjustment notches for each of the 4 wheels. It's as adjustable as you get.
Funny thing is that shortly after we purchased it, my older brother was not aware that 2-stroke engines require you to mix oil in the fuel. He ran it with straight gas until it overheated and stalled. 
I was able to get it running, but the compression was very bad. The interesting thing is that it's been running with almost no compression all these years. It still amazes me that I don't recall ever replacing the spark plug in it, and it has never fouled it. 
I really only use it these days in tight spaces where my Sears 17 hp lawn tractor can't get to.
