[AT] de-greasing disc brakes , disc brake fire and hauling hay

[Cecil R Bearden]

I just had a little problem with disc brakes on my 91 IHC 4700 truck.  
Of course they a little different than the tractor brakes.   This truck 
spent its first 19 years with the OK DOT.  I really did not know it had 
4 wheel disc brakes until I had to fix a flat on the duals...  It has a 
DT 366 w/ a 5spd trans and a 2 spd rear end.
I was using it yesterday to haul hay on my bale trailer that picks up 
round bales in a 5 bale row and swings out to the side and back behind 
the truck for loading.    I had hauled 3 loads and was heading back to 
the field when I smelled something hot like a clutch.   I had noticed 
there was not a lot of free travel on the clutch and thought I better go 
back to the shade tree and adjust the clutch.   By the time I got home, 
there was a small flame seen inside the left front wheel.    I got the 
water hose and flooded it for 20 minutes before it quit steaming!!!  
This was the first time I ever had problems with it, but the caliper was 
really dragging.   Not a good thing to have flames near dry hay!!

I got the semi with the low boy trailer and hauled the tractor and 
finished my hay delivery.

  I spent a small fortune on this truck when I bought it because it has 
a  hydraulic system with 7 circuits controlled by electric solenoid 
valves.   The valves are inside the 50 gallon hydraulic reservoir.  The 
truck was used to spread salt in addition to service as a dump truck.  
The bed powers up and down so it could hold the slat spreader solid when 
spreading.  I use one of the hyd circuits to power 2 solenoid valves 
that control the up and down and the swing function of the trailer.    
The only problem with this trailer is that the rails that the bales are 
supported are 4 inch pipe and very slick.   Bales will slide forward or 
rearward while in transport.   Originally it had chains that rode in 
slots that held the bales front and rear.  However with our rough roads 
here, the chains would jump out of the slots and lose on the road.   I 
have to hold the ends with cable come-a-longs.

When I could get in and out of the truck easily ( before the knee injury 
)  I could haul 20 bales an hour from the field to a customer 3 miles 
away.    Now, it takes me and my wife to move 15 an hour that far.    I 
am trying to design an arm on the front and rear that would hold the 
bales from sliding out.   Then all I would have to get out for is to 
connect the safety rod that holds the trailer from swinging out.  The 
cylinder holds the trailer at one side to swing and it could break a 
hose and swing out into traffic without the safety.

I don't have a picture of the trailer, but there is a link to the patent 
that shows several views of the trailer...
