Kubota BX 3rd function stops working when hot

[dwl_99]

Hey guys, i have a 5 year old Kubota BX2380 with a diverter on front that operates a grapple. When i use the grapple for 20 minutes or so, the pinch mode will stop working. Won’t open or close. Let it set for 5 minutes and it starts working again. My guess is that is overheats. Any ideas? Thanks!

Check the solenoids?

I Have not checked the solenoids. Can that cause intermittent failure when hot?

Did you find the culprit with the grapple function?
