Gradall 534D9-45 to G6-42P – telescopic handlers from Ohio: John Deere four-cylinders, 74 to 93.1 kW, 10,646 to 15,227 kg operating weight

Gradall Industries, based in New Philadelphia, Ohio, is best known for its wheeled excavators in which the boom itself is built as a telescoping arm; this telescoping expertise also fed into the company's own range of telehandlers for industrial and construction use. The ranges covered here, 534D9-45, 534D10-45, 544D10-55 and G6-42P, form the heavy class of this line-up.

The register lists here 4 versions with 74 to 93.1 kW rated output, operating weights of 10,646 to 15,227 kg and overall heights of 2,360 to 2,480 mm. The telehandlers are powered by John Deere four-cylinder engines of the 4045 range with around 4,502 cm³ displacement.

Telehandlers in this load and weight class are used on industrial sites, in steel and plant construction and for heavy lifting and placing work where the reach and lift capacity of a telescopic arm is required; Gradall competes here with JCB, Manitou and JLG.

On a used purchase, the condition of the telescopic slides and wear pads inside the boom, the tightness of the hydraulic cylinders, the John Deere engine's service history, tyre condition and the operation of the stabiliser legs count; spare parts run through the Gradall dealer network.

What to check before buying

Check the hour meter against the service records — a replaced instrument is the most common gap.
Compare the data plate and chassis number with the papers.
Check the weights in the papers against the figures here — attachments change them.
Load the hydraulics and watch for sag.
Ask about parts availability for this build year — the running costs hang on it.
