I have a Toro 72" side discharge zero turn mower. It quit

Customer Question

I have a Toro 72" side discharge zero turn mower. It quit going forward and backwards but the engine starts up fine?
I checked the V-Belt, hydraulic levels and all was fine.
Could it be the hydraulic pump? Would that prevent forward/backwards?
JA: Do you have fuel in the tank? If so, is the shut-off valve open and the fuel clean?
Customer: Yes and Yes.
JA: Do you plan on doing the work yourself?
Customer: The mower is a bit noisier as well
JA: Anything else we should know to help you best?
Customer: Yes I do my own work

It is very rare for both pumps to fail at the same time.

Thanks for this I formation. Have you noticed any oil leaks in your hydraulic system?

I have not noticed any leaks.
Hydraulic level was down a quart.
Regular oil was full and clean

Are you saying that you added a quart of oil to your reservoir?

I filled through the hydraulic dipstick port.

Thanks. Can you give me a minute or two, to look up your mower?

Customer: replied 11 months ago.
Sure can
Expert:  Donald replied 11 months ago.

I am back now. I took a look at images of your hydraulic system. I am not familiar with your particular transmission. Have you checked to see if your transmission is in bypass/roll position.

Expert:  Donald replied 11 months ago.

If you like, I can opt out to give another expert who is familiar with your hydraulic system, an opportunity to work with you.

Expert:  JON replied 11 months ago.

Alright, the 30721 is the model of the cutting deck.

Customer: replied 11 months ago.
Correct
Expert:  JON replied 11 months ago.

What is the model of the machine itself? The deck info contains no pump info. How many pumps does this machine have 1 or 2?

Customer: replied 11 months ago.
Groundmaster 327I believe it to have just one pump.So I can't lift my deck, go forward, or go backwards
Expert:  JON replied 11 months ago.

Yes, you have just one motor. There is a chance that it has gone out, but you could also just have air in the lines also. If you were 1 qt low, that had to go somewhere.

Have you attempted to crack any of the lines to see if fluid is coming out? You could have a bad line. if so, I would start by checking the main lines that feeds everything

Customer: replied 11 months ago.
I have not attempted that. I will try that now and will report back
Expert:  JON replied 11 months ago.

Okay. I will be around computer in shop, but may take a minute to respond if I am arm deep
