Bush Hog®
RDTH Rear Discharge Finishing Mowers

Available in 60 and 84-inches Models

Available in cutting widths of 60, 72, and 84-inches, the RDTH Series is designed to deliver a smooth, even cut with the superior distribution of rear discharge. Floating top and lower links allow for a uniform cut on uneven terrain and high blade tip speeds prevent streaking. Cutting height is easily adjustable from 1 to 6-inches. The closed box design and heavy rear discharge chain shielding reduces potential damage from thrown rocks and other debris.
