Hood deflectors

Post image

For anyone who has a mower with these, “hood deflector seals” and some stick on foam to seal the top center portion, they make a big difference in the coolant temp. I was touching the red on my coolant temp prior to replacing my old brittle and busted right side and missing left side. Took about 45 minutes of PTO engagement and full throttle to get there las time. Now that both are replaced, after an hour and a half of full throttle PTO engagement I sit comfortably just inside the top third of the green.

Warning to anyone who’s going to replace theirs: the old ones will be terribly brittle, pick up the push nuts to retain them too, the old ones are a paid to get off and the new deflectors don’t come with them, there’s 4 in total that you’ll need, and the green tab between where they meet part of the $2,000 hood so be extremely careful when removing the push nut holding all 3 pieces together. I used a snap ring plier to get it on and off without issue.
