This might help.

The wiring diagram shows the reverse switch is normally closed until activated. This would mean forward travel requires switch closed else PTO disengages... same as your experience.

From your description of progressive failure I suspect the switch has failed or has come loose and moved from it's normal position.

Go to the JD website below and search "reverse switch". A parts diagram should display. Look for item 15, part number LVA13307

The reverse pedal or linkage must somehow activate the switch.

There could be a problem with the PTO switch or safety interlock module or electrical interconnections so if the reverse switch checks out, further troubleshooting will be necessary. Start at the reverse switch and work your way to the PTO switch then the interlockmodule.

try this link... Ariens snowblower the wheels won go forward or backwards Google Search

Possibly the friction wheel or drive belt need to be replaced

Check your drive belt that it has not slipped off the drive cog under the motor. Also check the alignment of the motor with the handle on the right side (speed, reverse, and neutral lever).. This lever tilts the engine to engage the drive belt.. there is no transmission in this machine.. just how the belt engages by its angle when you push the lever forward and backward.. If the engine is running, it must be either the belt to drive the unit or the angle has been messed up somehow..

Here is a link that may help,ihttp://www.partstree.com/parts/?lc=lawn_boy&mn=28232. Adjust and lube the cables for drive engagement, and the other cables and Hiem joints. This usually will rectify the problem.

After I press the brake pedal my Kubota does move backwards or forward what can be the cause

Try lubing the linkage where it shifts from forward and to reverse the linkage is most likely freezing up or has snow or ice build up causing it not to shift, My thought is your shoving it hard enough that it finally engages when you get the snow or ice to break off.
