John Deere · COMPACT TRACTOR ATTACHMENTS
The John Deere 1R 25 has the same 17.8 PTO hp as the 1M 25 (18 in the public component) but a 915-lb lift at 24 inches, 157 lb more. That keeps heavier chippers like Woodland Mills WC68 (747 lb) and WoodMaxx WM-8M (775 lb) under the lift, though both are short on power. Light chippers and the 15-hp-class flails fit.
