Loader 4600 w460 loader controller problems

[Carter1225]

After brush hogging in heavy brush for 4-5 hrs, I noticed loader would not go higher than 3-4 ft off ground. It feels like handle will not go in full range. Bucket tilt works fine. Where do I start?

Did you look at the joy stick linkage maybe a its loose and getting caught .......

Can you swap bucket and boom hoses and see if the boom then works OK?

I hate to admit it but it works a lot better if all of the hydraulic lines are plugged in securely. Thanks for y’all’s time
