Backhoe boom won't lower it will go up fine but it doesn't go only over time you can hear it try a little but then it stops
Need a little more information like did the problem happen suddenly, while you were digging or after the machine sat for a while, etc. Is the boom lock malfunctioning? Is the valve spool moving full travel? Check the linkage to make sure it's not getting hung up or has dirt preventing it from moving. Also if it's broken.
