1120D With Steering Noise While Mowing Field

[Ohio_Pawpaw_Grower]

One of my RTV's uses is pulling a motorized bush hog. While mowing, I have never had any strange noises from the steering.

I recently added a spinner for the steering wheel, a gift from my Brother after he watched me negotiate my orchards.

After about an hour on the spinner's maiden voyage, on right turn only, I noticed a noise and what felt like a pulsation coming from the steering wheel.

I checked the engine oil and both hydraulic dipsticks before I got started - all full.

I will check it again tomorrow when it has time to cool down.

I wasn't whipping it - just normal turning speed made a lot easier on my wrists. But I am still suspecting that spinner has something to so with this.

Any ideas?

I can't imagine a spinner causing that noise.
I bought my 2015 RTV used and it already had the spinner on it. I planned to remove it but it is still on the steering wheel today. I don't use it that often but it is not in the way so it's still there.
I've been pulling a yard sweeper bi weekly with my RTV and making turns similar to what you make when mowing. I've never noticed the issue you mentioned.

I did not mean to suggest the spinner itself is causing the noise. I wondered if is was possible to over-heat the fluid or the steering valve by turning it a little faster. Either way, I am headed out in a few minutes to finish up. Will know more later.
