    I have a 5 year old Club Cadet zero turn with steering wheel. When you turn left, the left rear wheel locks up just before the front wheels are straight again. I thought it was the hydro gear box so I put a brand new one on it however backing it out of the garage was fine but going forward the left rear wheel is still locking up. you can turn right and go in circles you can turn left and go in circles but right before the tires are back straight that is when the left rear wheel starts locking up. I don't know if there is a air purge problem, no place on this particular model to do it or if its a linkage or what. The unit model is zc-dmbb-cagb-24px

    Your left hydro is probably not in true neutral when the steering wheel is centered. It could be a linkage adjustment or due to worn parts. Post up the info and I, as well as other members, will be able to look at the parts diagram, manual etc and possibly offer some suggestions.

    Model 17arcbda010, ser #1j204h10062, with rtz s54 fab under all that. Ok, another guy said definitely not the gear box, probably a broken bolt in steering sector, not allowing rod to fully engage thing on gear box.

    I went on the CubCadet website and cannot get any info on checking or adjusting the linkage. Look at the illustrated parts list, page 18. I would look for loose or missing bolts on part #5 and how it bolts to #29. I would look at page 16 and look at part #15 and #39. Obviously, look for any broken bolts, sloppy linkages etc and post back.
