Custom Post Type – Calling up content

I am new to php and have tried various means of calling up my custom posts to display on a page with a cut off of 150 words before the read more kicks in. However, I am getting the entire post to display, which i guess is better than nothing.

I am using the code below and could someone please help tweak it so it does what I want.

echo ‘<h3>’ . get_the_title() . ‘</h3>’;
echo ‘<p class=”pad10″>’ . wp_trim_words( the_content(), 150 ) . ‘</p>’;
echo ‘<p class=”farmer-more” style=”display:inline”>ID) . ‘”>’ . ‘Read More &raquo‘ . ‘</p>’;

Thank you.
