Different people have different preferences. I've had three tractors with loaders since 2002. Loaders are usually on between the last mowing in the Fall and the first mowing in the Spring. During mowing season, the loaders and frames have always been removed except when using the loader. The frame is just something to get in the way. It only takes a couple minutes to get the whole loader and frame on and off.
Access under the hood is a lot easier without the frame, and since I don't have the safety props I won't work under a raised loader. Your loader frame has a bar that crosses the hood. If you do remove your loader, be careful you don't miss the pins when taking it on and off.
