  1. Since AgPro (John Deere) retail store cannot help me in solving the issue of front tires coming off while mowing, I thought I would ask you.

    I have a 2006 John Deere 190C mower. I have replaced the wheels that should hold the bushings which almost worked mowing a 3 acre lawn. Then coming down a short hill the wheel came off losing the washer and snap ring. I also noticed my tires are not perfectly in line.

    What is your recommendation?


    • Hey Ed Southeard. Thank you for your query. Here are some things that you should check first-
      i. is the bushing alright
      ii. check the bearing
      iii. is the spindle good
      iv. level the deck mount

      Please update me. If needed, please mail me at lawntractorfixed @ with necessary videos and pics. I will be happy to solve your issue.

      • I hate the starting system on my 190-C John Deere. It’s a 2006 model I think, anyway I hate how you have to depress the break to engage the starter. I would like to bypass this altogether. Any suggestions? And don’t tell me not to do it. I have removed the mower deck and am tossing it, it’s no good. I just want to use my old mower to pull around a small trailor.
