8. MOUNTING THE LOADER 

 

CAUTION: Do not stand, walk, or work under a raised loader or attachment unless it is securely 
blocked or held in position. Accidental movement of valve handle/handles or leaks in the 
hydraulic system could cause the loader to drop, or attachment to dump, causing severe injury. 

 

CAUTION: Do not allow bystanders in loader work area. 

IMPORTANT: Never allow weight of tractor to be placed on parking stand when mounting or dismounting 
loader. 

 
 

8.1.1. To aid in mounting and dismounting loader, 
apply a small amount of grease, if needed, to each 
tower in areas of tower bottom receiver (A), tower top 
receiver (B), and inside handle pin hole (C).

8.1.2. Slowly drive tractor forward to a position where 
the hoses can be connected to the loader quick 
couplers. 

8.1.3. Stop the engine. Connect the loader hydraulic 
hoses to the correct quick couplers by matching 
colored nylon ties. 

8.1.4. Remove handle pins and snap pins from 
bearing boxes.
