Not sure what you are specifically trying to shield but hose protectors are like insurance. Especially smart if you have moving parts and hoses that can potentially rub and you depend on said hoses for income! They indeed are cheap insurance. Here is a good website for hose protection. I know the owners of this distributor personally and they are a top notch company.
Here’s an example of what I did to protect & hold up the hoses for the grapple. The hoses are wrapped with a cloth wrap supplied by a hydraulic hose fitting company in Spokane and the clamps are in place to secure the hoses to the grapple bucket and at the end of the support arm. It is well protected & out of the way.
I generally follow Kubota practice on the B21, where I have added hoses. So, I use metal spiral hose protectors on the backhoe, thumb, and backhoe aux hydraulic lines. I use metal or plastic spiral protectors where hoses lay against the transmission and other hard parts of the tractor. I use the plastic spiral protectors on the lines going out to the loader and quick attach. I use the soft woven sleeves to keep multiple hoses together neatly. The only place I have unprotected hydraulic hoses is tucked in close against the loader arms and the short factory loader hoses.
