Here is a pair of 1950's era, hard plastic Farm Toys  from IDEAL TOY CO..

A red Farm Tractor , I see no cracks or breaks , but the separate piece steering wheel has gone missing.

Also by IDEAL a neat  'JOGGING' LAWN MOWER. A wavy Washer causes the blades to jog.

Lastly only 1/2 of a cast iron cultivator toy.Might be Arcade.

Perhaps you see some items listed here     for your vintage Farm Toy collection.

Thanks for looking !
