Colton owned two pieces of land. He had a chicken farm on one land and a rubber plantation on the other. Colton had been selling chickens and processed rubber for 40 years. Recently, he has entered into several agreements in preparation for his retirement.

Colton agreed to sell 90% of his stock to Adam for RM80,000. The stock comprised of fairly new rubber-processing machineries and industrial chemicals, which Colton assured Adam that it would be useful for processing high grade rubber. Colton told Adam that the purchase was "truly value for money" and it was below the market price. Colton also agreed to sell all the rubber trees on his plantation to Ashley, a sawmill owner, for RM100,000. Colton agreed to deliver to Matt all his chickens worth RM60,000 in exchange for Matt's motorcar. Besides that, the land on which the chicken farm was located would be sold to Jojo for RM900,000.

Discuss whether the above agreements fall within the contract of sale of goods under the Sale of Goods Act 1957 ("SOGA").
