I want to share this with all you Jinma owners re transmissions. I have only seen two (that was enough) but if you ever feel the shifting fork break....ie it won't move the gears.....stop immediately, don't roll the tractor forward or backward and take off the top plate with the shifter and inspect and remove any broken parts else they will fall down and chip teeth off gears (not enough room for pieces to fall clear) and you will have to dismantle entire transmission and rear end to replace.
