I just bought a new to me 2006 Takeuchi tb175. I'm having a problem with the Dozer blade lever sticking in the down position and creeping the machine up slowly while you're digging or walking. It kind of sucks when you're walking and the blade is behind you and it starts dragging. If you move the lever back to the neutral position it will stay put until the machine starts bouncing a little. I was wondering if anybody has had a similar problem to this whether it be the cable that goes from a lever to the valve body or if it's something in the valve body. I know it's not on the lever side I've already had that apart. Where the cable goes into the valve body it's not a very accessible place. Any input would be great I appreciate it thank you in advance.
