I agree it doesn’t look steep but ZD1511 will not climb it with my 195lbs in seat all the way back & no weights up front.that does not look steep
I wouldn't rule out an older model. I was able to pick up a F2560E with 2000 hours for $5,000 in good shape last year. So far it has been great. Previous owner even threw in the 2 new tires and 4 anti-scalp rollers with the deal that he had not changed out yet. I use it for cutting rough ground such as horse turnouts. It handles rough ground better than the ZD1211.
Speaking of, was your used F that had to be split apart : cost a war pension to fix ?
