Kubota · COMPACT TRACTOR ATTACHMENTS
The current Grand L70 L4470 Premium produces 36.2 PTO hp through its three-range HST Plus transmission. It clears WC88’s 35 hp minimum by 1.2 hp, but that small power margin is a different question from feeding full eight-inch material at maximum speed.

FROM YOUR TRACTOR TO THE JOB
The L4470 Premium’s 36.2 PTO hp reaches WC88’s 35 hp minimum with a 1.2 hp margin. Choosing between WC68 and WC88 still means comparing branch geometry, feed expectations and implement mass: neither chipper’s full-diameter/full-feed condition is met by this tractor’s published PTO output.
Read the guide →FIELD GUIDEThe L4470 Premium’s 36.2 PTO hp lies within both researched WoodMaxx fixed hammer-mower ranges. The useful decision is whether you need a 55- or 70-inch cut and whether moving that cut sideways justifies a hydraulic version. Start with the actual mowing path and the rear valves installed on this tractor, rather than assuming a Premium or cab label includes the required circuit.
