I recently put a few posts on here about changing hydro sensitivity because its easy to tear the yard with the setup. Well What I did was bought some better tires and it is so much better. I bought the Carlisle Multitrac c/s tires. I bought them 1" wider than the original. They dont make a 21" so went with a 20". So the size is a 20-8.00-10. I cant tell a diiference in height between the tires side by side. GO figure! Anyways the ride is better, Handles better, doesnt tear anything unless going just too fast and also looks meaner with these wider tires! This is only my opinion/advise so you guys dont pick this paragraph apart, if you dont want to try then dont. anyways I am very happy with this mower now, feels like a whole new ride.
