All the implements which farmers use, planters cultivators, etc have gotten larger over the years as the scale of farms have grown. A 40 year old tractor likely isn’t going to have the horsepower to work with these new implements. Also, the old tractor is likely to lack a cab which could mean no climate control for you.
Both of these would be serious issues for operating a modern, large scale farming operation.
