    I have a 20 hp walker and when I engage the blades the engine seems to lug. The deck is 42in and the mower has 1300 hrs. Any ideas?

    Like you don't have enough rpm?

    When you activate the blades the mower lose power and then then regains power after 5-10 sec. It seems the rpms are lower. It's like the engine needs time to catch up. Thank you for any input.
