This is a high-pressure inflator for use on everything from car tires to semi tires. I would use a low pressure one for tractor, lawn mower, or ATV tires, or get a separate gauge for them, as this one loses accuracy under 20 PSI. From 20 PSI up to 120, it seems to be dead on.It is easy to read, you look through a little window that magnifies the numbers making them easier to read. I got this to replace one I had for years, that saw lots of use but was getting hard to read. They make rebuild kits, but I found this one marked down to about the same price as a rebuild kit, so this way I got a new hose and chuck for only an extra dollar or two. Top quality, and USA made. Will rebuild or replace with one just like it when the time comes, if I'm still doing wheel/tire work.
