When the hitching set-up is correct, raise the
sprayer with the tractor linkage, remove the locking
pin from the folding support stand and swing the
stand up to the transport position. Reinstall the pin
in the upper hole and secure it with the ‘R’ clip.

Hitching to the Tractor
The sprayer TPL (three point linkage) frame should
be level when the sprayer main frame is horizontal
and the tractor three point linkage is at a suitable
operating height. The sprayer main frame is
horizontal when supported by the folding leg on
level ground.
Connect the sprayer TPL frame to the tractor
linkage using the linkage pins supplied with the
sprayer. Set the tractor linkage to the required
operating height. Adjust the height of the swivel
hitch at the front of the sprayer so that the TPL
frame is approximately level.
The height of the sprayer hitch can be adjusted by
removing the four attaching bolts and installing it in
the high, mid or low position. The range of
adjustment can be further extended by rotating the
hitch whilst unbolted so that the tongue is either to
the top or the bottom. Ensure that the attaching
bolts are securely tightened.
The length of the drawbar on the TPL frame should
be adjusted so that the swivel hitch is
approximately mid-way between the tractor rear
axle and the sprayer axle to provide the best
turning geometry. To adjust the length of the
drawbar remove the two horizontal bolts and slide
it to align with one of the three bolt positions. After
adjusting re-install the bolts and securely tighten.
The tension spring supports the TPL frame when it
is disconnected from the tractor to facilitate
hitching. The length of the chain should be set so
that the TPL frame is approximately level when
disconnected from the tractor.
Connecting the PTO Shaft (PTO Model Only)
The sprayer TPL frame should be set so the PTO
shaft is approximately horizontal when attached to
the tractor to minimise the joint angles.
Clean and grease the splines on the tractor and
sprayer PTO stub shafts and install the PTO shaft
making sure that the spring loaded locking pins
engage in the grooves of both stub shafts.
Ensure that the tractor’s PTO shaft guard is
attached to the tractor.
The ‘U’ shaped hook on the sprayer TPL frame is
used to support the PTO shaft when it is
disconnected from the tractor.
Note: Upon delivery of a new sprayer it is the
selling dealer’s responsibility to install and set the
PTO shaft to the correct length. The following
information is provided for reference.
The telescoping tubes must overlap by at least 1/3
their length, but not less than 150mm, in all
possible operating positions and there must be at
least 25mm telescopic movement remaining at the
minimum operating length, refer diagram below.
If the PTO shaft has to be shortened cut equal
amounts from both male and female shafts and
safety covers. Carefully remove all burrs then
clean and relubricate before reassembling.
