I have 2013 Toro MX5060. Drive belt came off and took it into the shop. As we unloaded it off the trailer they noticed the trans was not disengaged, even with the levers pushed in. It had always been like this....and I just thought it was heavy and hard to push. The guy said no way should it be this hard to roll. The right side lever had always been hard to stay in. So, they will be checking this out along with replacing the drive belt. Does anyone have any experience with this issue? Mower runs fine for 9 years no trouble. But the thing has always had this issue with the levers as far as I know. I don't ever recall being anything but a beast to push. Is this an expensive issue or a minor thing?
