MXD52 Stump Grinder

MXD52 Stump Grinder

The MXD52 Stump Grinder will save you time and money. Two-speed ground travel reaches speeds up to 290 FPM/5.31 kph, getting you to the stump faster, and a 52″/132.08 cm boom arc means less positioning at the stump. Long Boom Technology maintains full boom arc swing regardless of cutting depth; piloted flange bearings increase bearing life and minimize exposure to dirt and debris; and an articulating front axle maintains stability on uneven terrain. Other standard features include 4.6-cubic-inch hydrostatic motor; and electronic toggled control panel functions. Wireless remote control with tethered back-up system, 4 x 4 drive system and spring-loaded Clic™ Dual package are optional.

  • Long Boom Technology – Long Boom Technology allows maximum swing above and below grade to access hard-to-reach areas while maintaining full boom arc swing regardless of cutting depth.
  • Hydrostatic Drive – Hydrostatic primary drive with belt final drive provides efficient (90% power transfer) transfer of power between drive and cutting system with minimal moving components
  • Boom Pivot Assembly – Heavy-duty boom pivot significantly reduces wear in critical area of the stump grinder to provide years of trouble-free service and allows for greater boom arm swing radius.
  • Articulating Front Axle – The articulating front axle maintains stability on uneven terrain.
