    If using a grass catcher, does the "blockage" or reduced amount of airflow out of the deck's discharge opening cut down on lift/vacuum?

    I haven't noticed a difference in vaccum when using an accelerator catcher but this question does spark some curiosity. I'll check more closely next time out.

    I haven't run an accelerator but those heavily perforated baskets they use shouldn't be that bad. When it gets close to full it's going to affect airflow.

    Now if you're talking rear bagging units with no belt driven vacuum then from my experience yes they affect airflow. The units with vacuum fans like the ultra vac don't affect it much at all if any that I have noticed. I can't say that it's a lift issue as much as it is a clipping/leaves discharge issue.

    When any bagger exhaust screen gets clogged or is dirty your performance drops.

    The belt driven blowers take away from the blade speed by slowing them down.

    Both lower your lift and create "back pressure" in the deck.
