ZD 331 Zero Turn Towing

[cptcrnch1]

Hi Kubota Newbie here. I've tried searching this exact question and I'm not finding exactly what I'm looking for, so hoping someone can shed some light on it for me.
I have a 2012 ZD 331 Zero Turn mower (diesel - pretty sure that's the D in zD). It has a hydrostatic transmission.
I just bought a property that this mower came with. The mower has been dealer serviced up to this point. I cut about 6 acres per week. I'm concerned that if I have any issues with the mower and have to get it back to the barn, how can I safely tow it back? I've read that some kubota models have a lever that releases the transmission so it can be towed and free wheel, however I can not locate this type of lever on my model. I have looked in my owners manual and it does not mention a level nor does not give specifics on releasing the transmission to free wheel.
I have noticed that on a hill, pointing down, if I shut the motor off, push both steering handles out laterally into a "neutral" position (position that they'd have to be in to start the motor), and take my foot off the brake, the mower will moved down the hill because of gravity. I'm not sure if this is considered 'neutral' for this transmission but it does move. I'm not sure if in this position, the transmission is or isn't in gear, but it will drift down. Is this 'neutral'?
That being said, is that the appropriate position in case it ever has to be towed? As in, if engine is off, brake is released and handles are in 'start'/lateral position - can it be towed in this position? I'm just thinking ahead in case I have issues and don't want to damage transmission. thanks for any input on this. Cheers! - JR

Welcome to the Kubota family! Unfortunately, on the zero turns like the ZD 331, there's no lever to bypass the hydro system. What you're describing when it rolls on the hill is exactly what you'd do to get it back to the barn. With the engine off and the handles pushed out to the neutral or park position, the hydrostatic drive motors are free to turn. You'll feel a good bit of resistance from them, but it won't hurt a thing to pull it slowly. Just don't try to tow it at 20 MPH down the road. A slow, steady pull is fine. It's a heavy mower, so be sure you have something with a good amount of pulling power and don't try to pull it with a small ATV or something. Hope that helps!

Putting the steering handles all the way out laterally does put the hydro in neutral, so it'll roll. That's generally safe for short moves, but for longer towing, a trailer is better to avoid stressing the trans
