I have had this machine a few months and used it for about 8-10 hours around the house, it already had this problem when I got it... in forward it seems to track basically straight... in reverse like back dragging it veers to the left pretty bad... if you skid to the right it seems fine... if you skid to the left it moans and wont do much... I checked the linkages and everything seems fine there... the brake doesnt seem to work I adjusted the nut on the linkage and didnt seem to matter either way the plate is tipped(I dont know which way is even suppose to be brake applied) the machine seems the same and it doesnt seem to apply the brakes at all.... Im not worried about the brake working, but I dont know if it has anything to do with the weak left side , I doubt it but I'm just throwing it out there.... I need to drain the "hydraulic" fluid because like a dummy I topped it off with actual hydraulic fluid,, instead of the motor oil it suggests in the engine compartment. is there a actual drain plug? where should I start on the weak left side. Thanks
