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.

Definitely a pressure drop. Probably need to add an oil cooler. Probably be good idea to change the transmission oil too

I found a nice oil cooler with its own fan on amazon that would make an easy install. Look up pit66 oil cooler. Add it to the low pressure return and mount it somewhere.

Thanks Art - will look it up. I am not real handy with hydraulics but have been researching one of those Samurai cutters for my tractor. It will require some plumbing so I will need to learn.

Have you tried driving without using the spinner to see if the noise is still there?

Just find the return line and make it loop through the oil cooler and back into the return. Place the cooler out of the way and wire the fan into a switch and relay. If your running an x model the oil cooler under the seat in front of the water pump fan might need blown out?
