Our tractors today are fitted with FEL's and hoses that older units didn't have. We don't use them strictly for tillage like our grandfathers did. They are exposed to many more inherent dangers to hydraulic lines, filters, hoses, etc...than ever. Even in the best design where a manufacturer tucks those filters and hoses above the drive line a stray stick can cause grief sometimes creating serious damage. I would think that some type of forestry protection such as a simple belly pans, filter guards, added hose protection, etc... will be offered in the future from companies that see the need for them. Until then we are left up to our own devices. The market may be too small for such an effort. It would be nice to be able to go to your dealer and order a belly pan and filter protection kit as an option.
