The hydraulic tank holds 170.3 litres. Working pressure is 206.8 bar. The engine fitted is the 4045T. Tyre size: 14,00 x 24. The Mustang Telescopic Forklift series covers 8 models. Rated output within it ranges from 100.4 to 1,170 hp; the 1155 sits at the bottom of that range with 116.6 hp.

Mustang telehandlers 519 to 1155 – the Gehl twins in red: the first digits as capacity in thousand pounds, the last as lift height in feet, John Deere 4045T engines of 4.5 litres, 74 to 116 kW, 6.8 to 15.7 t

Mustang's telehandlers are the red twins of the Gehl RS range: since Gehl of West Bend took over the Mustang brand in 1997, skid steers and telehandlers were sold identically in yellow and red, and after Manitou bought both in 2008 that continued until Mustang was absorbed into the Manitou brand in 2020. The type logic follows the American convention: the first digits give the capacity in thousand pounds, the last the lift height in feet – a 519 lifts 5,000 lb to 19 ft, a 642 6,000 lb to 42 ft, an 842 8,000 lb to 42 ft, a 944 9,000 lb to 44 ft, an 1155 11,000 lb to 55 ft. The engines are almost throughout John Deere 4045T, the four-cylinder turbodiesel of 4.5 litres regarded in North America as the standard engine of the class, at 2,500 to 2,600 rpm; a Deutz TD 2009 in the register belongs to a small model.

The register lists 8 versions with 73.8 to 116.3 kW from four-cylinders of 4,502 to 4,523 cm³, service weights from 6,849 to 15,717 kg and heights from 1,930 to 2,410 mm.

The American telehandler is the machine of building construction that lifts pallets, roof trusses and masonry to storey height – Mustang and Gehl competed in it with JLG, Genie, JCB and Caterpillar; the Manitou MT range continues the programme.

On used machines, operating hours, the condition of boom, wear pads and telescope chains, leak-free cylinders, load-moment limiter, axles and tyres and parts supply, which runs through Manitou and John Deere, count – a Gehl dealer knows the Mustang.

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.
