CORRECTLY SIZE PTO SHAFT
STEP-BY-STEP PTO SHAFT CUTTING GUIDE
EXAMPLE
1.
After hitching your FieldLink to your tractor using the 3PL arms, raise it a height where
the PTO shaft output on the tractor and the sprayer align horizontally with each
other.
2.
Measure INSIDE GROOVES
Measure from the groove which runs around the shaft on the
tractor to the same position on the FieldLink and take note of
this measurement.
890mm
3.
Remove the safety guards from either end of the PTO shaft.
4.
Measure NEW SHAFT (mm)
Push the two halves together so that shaft is at it's shortest
length and measure from one locking pin to the other; take note
of this measurement .
1194mm
5.
The required shaft length is the first measurement (from groove to groove) minus
a minimum of 76mm (3") to allow for disconnection from the tractor. If the shaft is
already shorter than this, ensure that minimum of 50% of total shaft length overlaps
when in operation.
6.
Amount to cut off shaft:
NEW SHAFT (Step 4.) - INSIDE GROOVES (Step 2.) + 76mm = CUT TOTAL
1194 - 890 + 76 = 380
7.
To find the length to cut of each end of shaft, divide the CUT TOTAL from
Step. 7 by two. Cut this length off each shaft.
CUT TOTAL ÷ 2 = CUT LENGTH
380 ÷ 2 = 190mm
8.
Cut the CUT LENGTH of both ends of the shaft using a hacksaw or metal saw. Remove burrs
from the inside using a file. Grease both ends of the shaft and slide them together to the
shortest length.
9.
Cut the same amount off both safety tubes from Step 7. Deburr ends and remove any plastic
shavings. Reinstall shaft safety guards to shaft ensuring they have locked in place.
Tractor models vary in distance between bottom link arms and the PTO shaft output, as
do implements, resulting in a need to adjust the length of your PTO shaft to ensure safe
operation prior to the first use.
WARNING:
Do not operate the tractor PTO until correct fitting has been checked. Doing so
will damage your pump and tractor.
