I see three problems with this broom. Hopper door is too small. Makes it difficult to dump in a truck. The hopper window is tiny. Why? How much would it cost to add a bigger plexiglass window for the operator to be able to see his load better? My third gripe is the gutter brooms adjustability. How long before you make them go further out? All those designs are fare behind your competition. Ive been in a sweeper for 10 years now and ran multiple brooms cleaning by behind mills. I live right down the street from your factory. If you would like some advice from an experienced broom operator let me know.
