non functionning hydrolics

I have a t135 Thomas and have had recent problems with the sensors from the ignition the seat and bar sensors. need to know how to bypass the entire system so as to not have problems anymore. just frustrating to deal with this. Im no mechanic but do understand instructions. Please help me snow has been around a few times and this is my only means of cleaning snow. Thank you all in advance. PS. this site is awesome.

Have you tried changing the sensors?
Just remember that the sensors are there to keep you safe, it's not recommended to remove or by-pass them. If you still want to by-pass the sensors, you will need to see if they are simply switches that you can install a switch on the dash to by-pass them.
