Trainer Peter Moody is putting his stable equipment up for sale in the wake of his decision to walk away from racing.

Equipment, ponies and other goods are set to go under the hammer, with Moody Racing announcing the sale via Twitter on Wednesday.

"Stable Auction Wednesday 9:30am- Stable Equipment, Tack, Truck, Ponies & miscellaneous stable goods suitable for 150-200 horse stable," Moody Racing said.

Moody, who trained the unbeaten champion Black Caviar, decided to call it quits this week after the 18-month saga over cobalt became too financially and personally draining.

He begins a six-month suspension on Friday for presenting Lidari to race with a higher than allowed level of cobalt in the 2014 Turnbull Stakes.

He was found not guilty of administering cobalt for the purpose of affecting performance, but guilty to two lesser charges.

He won't appeal the conviction, saying he's "over it".

"I will never be a large public trainer again," Moody said.

Moody was training around 300 horses and employed more than 50 staff.
