I doubt it, conspiracy theory notwithstanding

.....
If you were to take alook at most every Scut and L&G tractor that uses an
HST fan to directly cool the pump housing you'll find that every one of them has the cooling fan in harms way. It's an unfortunate nature of the beast since these fans are directly driven from the driveshaft. Even the units that utilize a vertical shaft engine and drive belt w/the fan on the top of the unit get their cooling fans damaged also.
Usually the MMM provides the protection for the vitals but in the case of a BX
TLB, Kubota should have provided additional protection since they recommend to remove the MMM when operating the BH on the BX24.
You may not have noticed but the
HST's fluid filter is lower than the fan, alot closer to the ground and all that would like to puncture it and it's right beside the mid
pto too..
Course the JD (2210 & 2305) & MF(GC2300/2310) SCUT's are in the same boat so it's not just a Kubota thing. Perhaps it's an industry wide conspiracy
I do agree that there should be an OEM skidplate option but then again, enterprising folks like Richard at Bro Tek offer a fine product to correct this OEM shortcoming.
