Check out a TRX 766 from Altoz. They are designed for wet, hilly, soft ground. They are a little pricey but might work for your situation.Because we never stop thinking about new machines... I started pondering a zero turn to replace my X350. Why? I don't know... but I was wondering if a ZT would handle some pretty wet spots in my yard better. I have some natural springs, and other drainage issues, so even when it is super dry, there are some iffy spots. I swung by the JD dealer just to look at ZT's (never considered one originally, my wife said she would use the tractor, but would never use a ZT, turns out she won't use either...), and the sales guy noted that ZT's can have better traction, since the tires that need to bite have all the weight over them, whereas my X350's engine weight is all over the little front tires. Never thought about it but had me thinking that Z530R could... maybe handle things better? Maybe I am just dreaming of something new... Let me know which is correct!
