Trying to figure out what went wrong, I've only put about 30 hrs on my I3040 using a 5ft BB, 5ft woods rotary cutter, 6ft rock rake and most recently a 6ft finish mower made by Bushhog. I was using the finish mower on somewhat uneven ground, looked back and noticed the mower over to one side, stopped the tractor and took a look, one TSB was broke completely in two and the other bend badly. I'm not sure if I was just being too careless slinging the mower around on the hilly ground or maybe the finish mower is to heavy (700 lbs) for the 3040. I will say the tractor had no problems handling the mower other than this issue, I really like the TSB's but was thinking I may need to go with heavy chains. Can anyone give me some advice on this?
