Large displacement high efficiency pump
Large displacement hydraulic implement pumps provide high flow output at lower engine RPM, operation at the most efficient engine speed.
|
|
Easy access
Engine oil check and filter locations integrated into one side to allow easier maintenance access.
|
|
Designed for durability
Large heavy-duty revolving frame guards and swivel guard help protect vital components from damage and debris build-up.
|
|
|
Ease of maintenance and serviceability
Provide a convenient and more secure work area in front of the engine. A new step provides easier access for filling the AdBlue/DEF tank. |
