Breakaway Cylinder Plumbing

Refer to Figure 5-7:

CAUTION

The breakaway cylinder is designed to bypass hydraulic ﬂuid

under high pressure when cutter head or parallel arms strike an

object during forward movement. Do not use any standard

hydraulic cylinder for a breakaway cylinder or damage could

occur to the unit.

The breakaway cylinder is used to prevent structural

damage to the cutter head and parallel arms. If the cutter

head strikes an object during forward movement, the

breakaway cylinder extends - allowing the parallel arms

and cutter deck to freely pivot 90 degrees to the rear.

The breakaway cylinder should be installed on the cutter

as shown in Figure 5-7. Be sure the rod end of the

IMPORTANT: A 1/2" bolt is installed for shipping

purposes only. This bolt must be remove before

connecting the hydraulic hoses to the tractor.

cylinder is located on pivot lug as shown. Connect both

hoses from cylinder to a remote duplex outlet on the

tractor.

Pressure Shut Down Valve Operation

Refer to Figure 5-7:

The standard pressure shut down valves supplied with

the breakaway cylinder inherently leak a small amount of

oil allowing the deck to drift back during field operation.

When required, reset the cutter deck forward during field

operation using the tractor's remote cylinder control

levers.

An optional replacement pressure shut down valve is

available that greatly reduces the frequency of cutter bar

drift but takes continuous force to move the deck back.

(Deck does not freely pivot back as it does when

using the standard pressure shut down valves).

See Land Pride’s Parts Manual No. 316-111P for

ordering either the standard or optional pressure shut

down valves. Order only genuine Land Parts from your

local Land Pride Dealer.
