Help with honda mower

[Ryan Lightning]

I have a 6-7 yeat old Hnoda HRC216 with hydro drive. The left wheel quit working alot of the time, It will work a little after it gets a push start from the right side. I havent torn into yet. Anyone know what broke? And what parts I need. Thank s for any :help:

take the wheel off and clean things up and it may work again. dirt gets in and gums up the works
