Hello,
A picture of the standard duty drawbar assembly is shown below. There is a heavier duty one which looks very similar
and is of heavier construction. The term 'swinging drawbar' relates to the fact that the drawbar is secured at a
pivot point on the underside of the tractor. The rear end of the drawbar can be adjusted to a central position or to
either side in two or more positions. This is useful if you have an implement that you wish to pull off-centre for
best performance perhaps. This drawbar assembly is quite simple as many are height adjustable as well. The mounting
brackets will attach to fixing points normally threaded holes in the transmission casing. There would be no problem
in fitting a 1" bolt to the front as long as it is of suitable quality for the job however it would be advisable to
fit the correct pin as the 1130 is a large tractor and capable of a large pulling force. The part number for the
correct plain anchor pin is 367 073X1 or 366 601X1. The tractor serial number will confirm which is correct. It is
essential that the drawbar is secured in whichever position you choose to use it. The pins to secure the drawbar are
195 356M1, two are needed. Serious damage and possible injury can be caused if using a heavy or PTO driven implement.
Pressure Control is a feature of the hydraulic system that allows you to do exactly that. In the Position Control
section of the quadrant full hydraulic pressure, 2500 to 3000psi is available when you raise the lever to lift an
implement for example. When the lever is in the lower area of the Pressure Control section the hydraulic pressure
available is around 500psi at minimum. As you raise the lever the pressure will increase to the full pressure before
you move into the Constant Pumping section and then into the Position Control section. Pressure Control was designed
to be used with an additional linkage hitch assembly to provide a means of transferring some of the
implement/trailer's weight to the rear wheels of the tractor to increase traction. A chain is attached to the
trailer/implement drawbar to achieve this. It was a very successful accessory but was underminedwith the
proliferation of 4WD tractors.
