Description

This Cat 1 hydraulic top link replaces the mechanical top link on your tractor. Adjust its length using the tractor hydraulics to change the implement's working angle from the tractor seat. It has a 390–500 mm length range, 110 mm stroke and 50/30 mm cylinder bore/piston rod. Supplied with 2 hoses with quick couplings, 2 banjo bolts and 4 sealing washers.

CAT 1-1 · 390–500 MM · 50/30 MM

Check the fit before ordering. Compare the required length, both mounting points and available clearance with the technical drawing. Category or tractor make alone does not confirm a suitable fit.

What is included?

  • 1 × hydraulic top link
  • 2 × hydraulic hoses — DN10 / 3/8″ SAE 100 R1AT; 75 cm; male 1/2″ poppet quick couplings
  • 2 × banjo bolts — 3/8″ BSP
  • 4 × sealing washers

The 75 cm length includes the quick coupling and is measured from the centre of the banjo eye to the tip of the coupling.

The hydraulic locking block is the valve block on top of the cylinder. Check that the quick couplings match your tractor and that the hoses have sufficient clearance throughout movement.

Will this version fit your tractor?

Both ends have ball joints for a suitable Cat 1 three-point linkage. A double-acting hydraulic connection is required to extend and retract the cylinder. The 50/30 designation means a 50 mm cylinder bore and a 30 mm piston rod, not the mounting-hole diameter.

What does the extended version mean?

This version measures 390 mm retracted and 500 mm extended. The shorter 360–470 mm Cat 1 top link also has a 110 mm stroke. Extended therefore refers to a different overall length, not a greater adjustment travel. Choose the length range required by your tractor and implement.

Checks before installation

  1. Compare the required retracted and extended lengths with 390–500 mm.
  2. Check both mounting pins, hole diameters, joint widths and available clearance.
  3. Check double-acting control and tractor quick couplings. G3/8″ is the cylinder port size, not the tractor quick-coupling specification.
  4. Route the hoses without kinks, tension or contact with moving parts.

Need a different length or a hook end?

Compare standard Cat 1 hydraulic top links or Cat 1 hydraulic top links with hook. Check each version's mounting dimensions separately.

Frequently asked questions

Does it fit every Cat 1 tractor?

No. Check the length range, both mounting points, available clearance and hydraulic connections.

How do I measure the required top-link length?

Measure between the centres of the two mounting holes. Check the shortest and longest lengths needed by your tractor and implement, then compare them with 390–500 mm. Do not measure only the cylinder barrel.

Is the 110 mm stroke the same as the overall length?

No. Stroke is the cylinder's travel. The retracted length is 390 mm and the extended length 500 mm, measured between the indicated mounting points.
