Having a lawn is a blessing, for sure, but I do not want it to turn into a curse. While I much prefer to do my own yar dwork, because I am reassured the work is performed to my exacting standards, I am always reading up on the tools of the yard care trade.
There are 3 types of handwheels. Handwheels allow the precision I want with the help of a mechanical adjustment. The solid disk, whether with 2, 3 or more spokes are where I looked for the right type of handwheel. While they are sold also without any handle, and also without the retractable handles, I prefer my 3-spoke handwheel (and I also like my newly acquired toggle clamps).
They are made out of steel, cast iron, aluminum, stainless steel, and plastic. Cast iron can be brittle and involves work to keep it working, while some plastics are just shoddy. I stick with aluminum or steel. Aluminum is lighter weight, durable, and requires almost no maintenance. Stainless steel is great, but it costs more.
Mine has a clutch to keep me safe. The built-in indicator is a must-have for the precision I want. That’s the basic idea of the types of handwheels and my personal preferences.
