VRT HYDRAULIC DRIVE 

– MAINTENANCE 

Page 91 

05/06 

Introduction 
 

The  VRT  Hydraulic  drive  metering 

system utilizes robust and reliable hydraulic 
and electrical components that should offer 
excellent  service.  It  is  suggested  however 
that  regular  maintenance  checks  are 
carried out on a yearly basis. 

 

Yearly Checklist 

 
At  the  beginning  of  each  season, 

operators  should  carry  out  the  following 
checks. 

 
1.  Hydraulic system:- 
 

  Replace  the  oil  filter  on  the  seeder 

and  tractor  at  regular  intervals.  The 
seeder’s  filter  should  be  replaced 
every  2  to  3  seasons  depending  on 
the usage. 

  Check 

for 

oil 

leaks 

at 

hose 

connections,  valves  and  metering 
drive  motors.  Repair  or  replace  any 
worn or leaking hoses or seals. 

 
2.  Electrical connectors and terminals:- 
 

  Check 

all 

breakaway 

electrical 

connectors 

for 

contamination, 

corrosion or damage. It is critical that 
the actual pins and receptacles have 
an excellent contact. 

 

 

Fig.VM1   VRT breakaway connector. 
 

  Check the power take off terminal at 

the  tractor’s  battery.  Remove  and 
clean if necessary. 

  Check that the electrical connector at 

the rear of the monitor is secure. Do 
not over tighten. 

  Inspect  VRT  loom  routing  on  the 

tractor  and  implement.  Replace 
broken  cable  ties.  Add  protection  or 
move cable routing if necessary. 

 
Proximity sensors:- 
 

  Check  proximity  sensors  on  the 

metering  drive  hydraulic  motors  for 
clearance and operation. 

  Check  proximity  sensor  on  the 

ground  drive  wheel  (left  hand  rear 
wheel)  that  monitors  ground  speed 
for clearance and operation.  

 

Proximity Sensor 

 

The  proximity  sensors  are  used  to 

record  motor  speed  and  ground  speed. 
Their  feedback  is  critical  to  the  accurate 
operation of the VRT equipped air seeder. 

 

Wheel

 Proximity Sensor 

 

To  check  that  the  Wheel  sensor  is 

operating correctly you will need to jack the 
left-hand  rear  wheel  off  the  ground.  With 
the monitor on, and seeder connected, spin 
the left-hand rear wheel. A small light at the 
cable  end  of  the  sensor  should  flash  every 
time  a  target  tooth  goes  past.  Also  check 
that  the  wheel  bearings  do  not  have 
excessive play. Adjust if necessary.
