The Cobbs 4x4 Weeks of Speed Gunnedah 2021 celebrations commenced with The Rural Museum tractor trek and official launch street parade on Saturday morning.

Tractors, utes, bikes, model aircraft and all sorts of cars from drag to street stockers and speedway cars flexed their way down Gunnedah's main drag.

Weeks of Speed Committee president Ray Darcey said the parade and tractor trek were one of the biggest they have had.

But he said Saturday night's speedway racing topped the parade, drawing a couple of thousand people.

"The speedway meeting on Saturday night was the biggest speedway meeting during Weeks of Speed ever," he said.

"It was a massive crowd out there Saturday night, with 94 cars nominated and it was absolutely fantastic."

He said last year's parade being cancelled due to COVID-19 made a big difference to the turnout, because people "were sick of sitting at home and wanted to get out and about".
