4.0 PTO.
The PTO is a very important item. It drives the machine from the tractor and ensures the safe
operations when correctly maintained and installed. The PTO shaft has its own CE certification. Read
the PTO shaft manual, which is connected to the shaft itself
.
4.1 PTO LENGTH.
The length of the PTO is very important. When too long, the transmission of the tractor and/or
VERTI-DRAIN may be damaged. When the overlap length of the tubes drops under 150 mm (6")
anytime, the PTO may be damaged.
* the length changes when the machine is raised or when another tractor is used.
To cut the standard PTO from new or for another tractor, work as follows (see fig. 3):
1. Measure the distance A between tractor PTO shaft and VERTI-DRAIN PTO shaft from groove to
groove when machine is on the ground at correct angle and attached to the tractor.
2. Measure the length B of the PTO in its shortest position from lock pin to lock bolt.
3. Split PTO in two pieces and remove safety cover from each end
4. Both tubes and safety cover ends should be shortened: (B - A) + 75 mm (3").
5. Deburr all items, use some grease and put all parts together.
6. Assemble the slip clutch side of the PTO to the VERTI-DRAIN transmission.
* Torque for lock bolt should be 80 Nm (700 lb.in.)and checked every 40 hours
7. Connect other side to the tractor.
8. Check overlap of tubes.
* Never run machine with a damaged PTO safety cover. Replace it first.
