Rode over hose and now it won't go into gear, forward or back

Above is the manual for you mower. This answer assumes that “won’t go into gear” means you can move the control lever into reverse, neutral and forward but the mower doesn’t actually move in those directions. If this assumption is wrong, and you can’t move the control lever itself, then you have a problem in the lever linkage or the transmission.

Most likely your drive belt has either broken or come off the pulley. Pages 24-25 in the above manual shows the installation of the belt (“To Replace Motion Drive Belt”). In layman’s terms… Look under the mower right below the engine (It helps to drop the mower deck to its lowest position). You should see a shaft coming down with two pulleys attached (see Page 24, Item “M” in the Figure). There will be a small pulley towards the top of the shaft, and a larger pulley at the bottom of the shaft. You want to inspect the belt that goes around the top pulley - it should be tight. If the belt is broken, you will need to replace it. If it is loose, then you need to check the belt routing on Page 25, and make sure it didn’t come off one of the other pulleys. If the belt is routed correctly and still loose, that means the belt has stretched and will need to be replaced. Hope this helps.
