[AT] Hydraulic hoses

[Will Powell]

I'm with Mike... 

I have an old Mcconnell 3pt Back hoe that will not allow movement unless the system is under pressure, a nice safety feature. Though, I do leave it up, but perhaps I will lower it to the ground to relieve the load, makes sense. 

I was over at my neighbors house and his son was playing on his back hoe and dropped the bucket, "boom".... Thankfully nobody was under it. I was amazed that it could happen because my 1960's backhoe would never let that happen..... I told my neighbor that maybe he should drop the bucket when he was finished with it.... 

Regards, 

Will

Not to lecture, but the instructions for virtually all hydraulic 
equipment state, when done with the machine even for only a few minutes, 
to lower everything to the ground and relieve the pressure on all valves 
by cycling them. There are two issues here: 1. safety - a raised boom or 
other tool can drop very quickly if someone accidentally moves a lever 
or a hose fails, and it could fall on someone in the area, and 2. 
leaving pressure on the system when idle puts a strain on the system and 
can cause premature wear (especially old hoses). Also, kids love to play 
on idle machines and love working all the levers. 

Just my 2 cents,
