When Diggs, Carrie, and Scooch dig a trench in the wrong place they think they’ve struck oil.

Diggs is jealous when Scooch chooses to work with Carrie instead of him.

Carrie chooses to horse around when the machines are clearing out an old dock, and has to be rescued by Carl.

The machines must clear an old dumpsite to make way for a new car park in just one day.

One day as the younger machines play by the docks, Carl and Lug reflect on their own carefree youth.

Bozer tells the machines that it's "out with the old and in with the new," to Carl and Lug's chagrin.

Carl and Lug have had a bit of a falling out and have even stopped talking to each other.

A new dump truck has come to the site – Skatch. He’s so exciting and so much fun that Diggs and Carrie seem to be ignoring their old pal, Scooch.

It’s very cold today and Bozer reminds the machines to put in their anti-freeze - but then forgets to put some in himself!

When Diggs overhears Bozer talking to himself, it seems that their beloved boss is going to be leaving.

Carrie thinks she’d make just as good a boss as Bozer and when he gives her the chance she’s determined to prove it.

Bozer gives Scooch the morning off so he’ll be rested for a big job in the afternoon but then the other machines start asking for help..

Diggs’ job doesn’t seem as much fun as Carrie’s and Scooch’s.

When Lug tells Scooch that grading a road on your own is what every dumper dreams of, the little truck decides to do a bit of solo grading himself.

When Diggs discovers that Bozer has accidentally dozed a load of gravel over some important bridge rods he faces a dilemma.

Diggs and Scooch think they are helping Bozer save time by starting work on their own, but dig in the wrong place.

Carl is preoccupied because he is missing the site where he was made.

Diggs has a shiny new attachment and is very proud of it - but doesn’t know what it does!

Scooch would like to find something he can do that Diggs can’t.

Carrie is a little jealous when the bigger machines get to landscape a new park so she decides to invent her own fork-lifting style.

When Bozer tells Diggs that he’s full of good ideas, he shares them with Scooch and Carrie. But Carrie’s got a few good ideas of her own!

Everybody’s reversing warning is clear and impressive – everyone’s except Scooch that is.

Lug scoffs when he sees the newer machines playing at being Big Rig – the superhero truck – everybody knows there is no such thing as “extra vroom”!

When there’s cement mix to be moved and Carrie’s feeling fired up, nothing can stop her – nothing except a flat battery that is!
