Good morning. Now is the time to have your equipment ready to go for spring. I would check some of the following. It is cost effective to service now versus downtime and sending out a road mechanic,
Battery-Check charge and connections
Fluids-Check Coolants and all oils.
Complete walk-around to look for hydraulic and oil leaks. Also any loose wires or worn parts that need to be replaced.
Couplers-Check all quick couplers and extra hydraulics.
Good luck and have a great year!
