Valery, that just means you're healthy. How is the Russian phrase used, in what context?

“Да на нём пахать можно” — о сильном, здоровом, обычно, не работающем физически человеке.
У него здоровья столько, что можно пахать на нём как на лошади.

Спасибо!!

Valery, your definition doesn’t quite express this. The only we sometimes use is SOUND AS A BELL, but that’s usually said by someone who recovering from an illness (mental or physical) and is starting to feel better.

yes, and it’s what we say in this context

Уже глянул. Для мултитрана нет надежды.

They do the same thing you do - they copy and paste from dictionaries without giving any thought to context or usage.

You did it here and it can mislead a lot of learners.
