Kubota · COMPACT TRACTOR ATTACHMENTS
The L3902 has 32.1 PTO hp with the gear transmission and 30.3 with HST. Those figures put both versions above the WC46’s 30 hp ceiling and below WC88’s 35 hp minimum, so a larger tractor label does not simply unlock every smaller chipper.

The linked sheet labels the system-pressure row “kgf/cm² psi” but prints 165 (16.2) for L3902; these labels and magnitudes do not form a usable psi pair.
Pressure remains unknown. Do not silently relabel or convert the row. Confirm against the serial-specific operator/service information.

FROM YOUR TRACTOR TO THE JOB
The L3902 sits between two chipper boundaries: its 32.1 gear / 30.3 HST PTO hp exceeds WC46’s 30 hp maximum but falls short of WC88’s 35 hp minimum. WC68 occupies the useful middle range, with a separate restriction on full-size, full-speed feeding.
Read the guide →FIELD GUIDEOn the L3902, an unclear mower horsepower basis can reverse an upper-limit decision: 37.5 gross engine hp is above the LFS family’s 35 hp maximum, while 32.1 gear and 30.3 HST PTO hp are within it. After resolving that basis, compare the actual swath with your tire setup.
