Need to make sure that there is clearance for the hood to open. Because the grill slopes outward the Kubota guard folds forward for this purpose. Just thought I would mention that if you are going eBay which might be an aftermarket item. Mine came as part of the LA 844 FEL package. I looked to see if it was listed as a separate price on the bill of sale. It wasn't.
The guard part has a spring loaded release pin that allows the dealer supplied unit to fold forward giving clearance for the hood to open.
