Cub cadet, first Cub I used/owned was a 135-hope I got the number correct. After moving into new area in 2015 , neighbor offered me, in 2016, to go 1/2 on his already owned cub with original cost-$600. First yr was great, but due to my failure of PROPERLY checking oil, engine failed in 2019. I replaced the cub for $600, it quickly had problems. First, the weld between the wheel shaft and the wheel cracked, making the wheel wobble. After mfg replacement, the other wheel did same. Mfg replaced both wheels & hubs. Next the tire went flat.
Based on the original neighbors cub, mfg reduced the size of the weld from about 1/4 inch to about 1/16-1/8 inch thick. Also, they started using tube tires--original was tubeless--I fixed with flat tire repair spray purchased at auto parts store. All 3 problems cost me about a total of 2.5 months use. After all repairs, have used the cub frequently with no problems.
