I have 2 walkers currently one is an mt model with the high lift option. It is so tail heavy that it does not like hills much and tends to want to tear turf when driving along them across the face of the hill(several it is not an option to go up and down the hill). I was looking at walkers tail wheel lock kit. Does anyone use this? How has it performed? Were you happy with it? Is it complicated to use? Also do you have to be going straight to turn it on or can you flip and switch and it maked the tail wheel go straight. I guess i just do not understand how this system. Id like to know more about it but doesnt seem to be much information out there about it.
