thanks for that info. the xtx 185 at work has gone to the garage for the second time in two weeks it is to do with the gears in her it seems like the sensor is gone in our one two from what you are saying. the back end in the 185 also gives us trouble from time to time. she has being all over ireland in different garages and they all do little modifations to the brakes at last a short while then go again. we had a 175 that gave a pull of trouble it was always in the garage then that was swapped for the 185. it must be a a thing with big mc cormicks because our small ones never give any trouble ad they are the 2 mtx 140 and the mtx 135. plus their is a lot of small mc cormicks up to mtx 140 around me and they always are going fine. we have the only big one around the place and it is the only on the dealer has sold.
