Ford 755B Tractor-Loader-Backhoe Specifications

Below are the factory specifications for the Ford 755B Tractor-Loader-Backhoe, transcribed from the operator's manual (manual code SE 4680 1188). The 755B was the largest of Ford's 755 industrial TLB line, built from approximately 1987 to 1992, with a turbocharged four-cylinder diesel, a 3x3 power-shift power-reversing torque-converter transmission, and an integral backhoe offered in standard 17-foot and 17-foot extendible-dipperstick configurations. Where the source manual contained a printing or conversion error, the value is footnoted rather than reproduced silently. You can download the complete Ford 755B operator's manual below.

Cylinders & Weight

Loader and backhoe cylinders	Double-acting
Weight — 17 ft. (incl. cab, loader & backhoe buckets)	18,000 lbs. (8165 kg)4
Weight — 17 ft. extendible dipper (incl. cab, loader & backhoe buckets)	18,700 lbs. (8482 kg)

¹ The manual prints displacement as “268 cu. in. (4195.9 cc).” These two figures are inconsistent: 268 cu. in. converts to about 4,392 cc (4.4 L), while 4195.9 cc equals about 256 cu. in. (4.2 L). External references (TractorData, TractorTechSpecs) list the Ford 755-series engine as 268 cu. in. / 4.4 L, so the printed metric value appears to be a misprint. The displacement above is reproduced as printed; treat the cc figure with caution.
² Source unit correction: the manual prints these metric values in millimeters (e.g. “33 mm,” “378.4 mm,” “432 mm”), which is clearly a typo — the matching imperial values (13 in., 12 ft. 5 in., 14 ft. 2 in.) confirm the units should be centimeters. Corrected to cm here.
³ “INA” is the manual's own notation (Information Not Available) for that figure on the extendible-dipperstick configuration.
⁴ Source OCR/print correction: the manual shows “18,00 lbs.” for the 17-ft machine, which is incomplete; the paired metric value (8165 kg) equals 18,000 lbs, so the weight is 18,000 lbs. Published operating weights from external sources vary by configuration (roughly 16,900–18,000 lbs).
