Yanmar 6′ 300 Series Rotary Cutter

Description

Yanmar YRC306 6-Foot 300 Series Rotary Cutter

The YRC306 is the 300 Series 6-foot rotary cutter in Yanmar’s attachment line, listed separately from the 200 Series YRC206 models. Like the rest of the family, it is a single-spindle brush cutter with free-swinging heat-treated blades, a pan-type stump jumper and full-length skid shoes, built for pasture, field edges and overgrown ground.

What We Know About This Model

Yanmar has not published a separate specification sheet for the YRC306 alongside the R and SCR models, so its width is the key confirmed fact: a 6-foot cut suited to larger compact and utility tractors. The general cutter features Yanmar lists across the range apply, including a cast iron gearbox and standard metal rear guards. Hitch category and weight should be confirmed on the unit at delivery rather than assumed from the 200 Series.

Before the First Cut

Every rotary cutter needs its gearbox oil level checked before first use, since units can ship with oil at a minimum level for transport. Setting the tail wheel so the deck runs slightly lower at the front than the rear gives a cleaner cut and discharges material more evenly, and the PTO driveshaft length should be checked against the tractor so it neither bottoms out nor pulls apart when the hitch is raised.

Comparing 6-Foot Options

Buyers choosing a 6-foot cutter can compare the YRC306 with the YRC206R, which uses a shear pin, and the YRC206SCR with a slip clutch, both of which have full published specifications. Smaller tractors are better matched to the 5-foot YRC205R.
