5.5 Attaching the Fusion 3 to a 540 rpm PTO
All mechanical functions are related to the correct PTO speed. Follow the instructions
as supplied with the PTO unit for correct assembling of the PTO shaft to the tractor
(See “PTO Shaft adjustment & maintenance” on page 55). Ensure PTO cover-guards
are prevented from rotating, by securing the chain to the tractor.
5.6 Lighting system
The 7 pin plug of the lighting system on the machine must be connected to the 7 pin
socket on the tractor.
5.7 Fusion 3 set-up & tractor hydraulic system
There are 3 systems found on tractors, as outlined below:
1. Open Centre: This is the most common system on smaller tractors (less than
60kw) and also on some bigger older tractors. In this system, all the oil flows
through the control valve, when the machine is idle. The tractor will have a fixed
displacement pump and the output flow will be max. 60 litres/min and flow is
usually not adjustable.
2. Closed Centre: Although not so common on today’s tractors, this system is
still found on the older John Deere models (pre. 00 & 10 series), but also on
some other makes and particular models. In this system, no oil flows through
the control valve, when the machine is idle, but maintains max. oil pressure in
CAUTION: Release hand brake
Always ensure the hand brake has been released before moving the
Fusion 3 on the road or operating in a field.
CAUTION: Standard PTO of 540 rpm, maximum = 610 rpm
The McHale Fusion 3 should be driven with a standard PTO speed of
540 rpm. The maximum PTO speed allowed = 610 rpm. A PTO speed
above 610 rpm is likely to cause damage to machine components. Do
not use any faster PTO speed other than specified above!
NOTE: Check lighting system before travelling on the road
Before travelling on a public road, the operator must ensure that the
complete (tractor and machine) lighting system is in a fully functioning
condition.
CAUTION: Hydraulic System Setup
It is very important to determine the correct hydraulic system on the
tractor, as a wrong set-up will cause serious damage to the tractor
hydraulic system, or at least excessive heating of the oil.
