Although not an excavator driver, I’ve worked around them and have gained an understanding….
I hired one for a weekend a few years back. The only thing I underestimated was the total lack of power of a 1 tonne machine compared to the 20 +tonne ones I’m more used to being around.
Put about 2 cube of topsoil into me 8 yard skip from the front with the intention of dragging it around the side but the excavator simply wasn’t man enough. Only option was empty it or drag everything from the back to the skip at the front.
I chose to drag about 4 cube of soil to the front, after I’d dug it up.
There’s no way I’d have taken on an excavator without a knowledge of how they move, operate, behave etc. or you will spend the first few hours working out how they move.
