4.0 gpm machine doesn't draw well from a tank

Nope, I didn’t spend the money to get a Cat… AAA direct drive for me. Still no buffer tank or fancy unloader to make wash life better, lol

Here’s a look at the difference between direct drive and gear drive. The gear drive uses two shafts connected to each other by two gears which make up a reduced drive. You’ll be able to easily spot the offset configuration that this creates.


oh yeah ok gotta look again

We need to pass around the hat or something. I love my puny buffer tank but the flow unloader is the biggest game changer so far. This job will get much, much easier whenever you are ready.

Edit: don’t think of it as double the GPM, instead cut the square footage & time in half.

Builds character! I did the elevated buffer tank with my 4 gallon washer and truck ramps to unload and load each time I used it for two years.
