New adjustable-width tracks and a new backfill blade with foldable end sections allow the new John Deere 17D compact excavator to work in areas normally restricted to smaller units. When the tracks are retracted and the blades’ end sections folded, the machine fits through a 40-inch opening. When fully extended to more than 50 inches, the undercarriage provides stability for excavation and other operations. At an operating weight of 4,364 pounds, the reduced tail-swing 17D provides improved performance specs, including a 20-percent increase in horsepower, an 8-percent gain in arm force, and a 19-percent boost in bucket dig force.
