Kubota LX4020
Attachments that fit.

The LX4020 is the LX3520’s frame with a stronger turbo engine: 39.8 gross hp and 32.6 PTO hp, 3.9 PTO hp more than the LX3520HSD, with the same 1,962 lb of lift at 24 inches and the same 53.7-inch width. That extra power still leaves it 2.4 hp short of 35-hp chipper minimums, and the cab version lists 1.4 hp less.

Scope of this guideHSD · 3-range HST · 4WD · ROPS · standard width. Each configuration below states the model and equipment covered by its sources.

Screen PTO-rated attachments against 32.6 hp on the open-station HSD, or 31.2 on the cab. Engine-rated attachments use 39.8 gross hp (SAE J1995). Use 1,962 lb at 24 inches, not the 2,535-lb lift-point figure the web page shows in its 24-inch field.

  • Kubota’s LX20 specification sheet lists 39.8 gross hp (SAE J1995) and 32.6 PTO hp for the LX4020HSD, and 31.2 PTO hp for the LX4020HSDC cab.
  • 32.6 PTO hp misses Woodland Mills WC88’s 35-hp minimum by 2.4, and is 2.6 over the 30-hp ceiling of WC46 and TFG55.
  • WoodMaxx WM-8M (19 PTO hp minimum) and MX-9900 (25) are the 8-inch chippers inside their published minimums.
  • 39.8 engine hp is 2.2 short of Land Pride FM2572’s 42-hp minimum, so FM2572 is out on either basis; FM2560 (33) depends on the basis.
  • Lift is 1,962 lb at 24 inches and 2,535 lb at the lift point, identical to the LX3520HSD; the web page labels the 2,535 figure as 24-inch lift.
  • The 2026 catalog prints 2,624 lb under the LX4020HSD, which is the cab weight in the specification sheet; the open-station HSD is 2,191 lb.

Where the documents disagree.

Tractor weight

The 2026 catalog’s LX20 table prints 2,624 lb under LX4020HSD. The LX20 specification sheet gives 2,191 lb (994 kg) across the LX3520HSD and LX4020HSD columns and 2,624 lb (1,190 kg) across the LX3520HSDC and LX4020HSDC cab columns.

2,624 lb matches the cab weight, so 2,191 lb is used for the open-station HSD. Weight does not change an attachment screen; confirm it before planning ballast or trailering.

Lift 24 inches behind the lift point

The current LX Series web page lists “3-Point Hitch Capacity 24in behind” as 2535 for the LX4020. The specification sheet gives 2,535 lb at the lift point and 1,962 lb at 24 inches; the 2026 catalog gives 1,962 lb at 24 inches.

1,962 lb is used for lift at 24 inches and 2,535 lb for lift at the lift point. The web field appears to carry the lift-point value; the same mislabel is recorded on the site’s LX3520 profile.

Hydraulic flow

The current web page lists 9.1 gpm for the LX4020. The specification sheet lists 9.5 gpm total pump output for the LX3520HSD and LX4020 columns and 9.1 gpm only for the LX3520DTN narrow gear tractor.

9.5 gpm from the specification sheet is recorded. Neither figure is rear-outlet flow; no attachment on this site requires tractor hydraulic flow.

FIELD GUIDE

Kubota LX4020 wood chippers: 2.4 hp short of WC88, inside the 8-inch WoodMaxx minimums

The LX4020’s 32.6 PTO hp is the most in the LX20 range, but it is still 2.4 short of Woodland Mills WC88’s 35-hp minimum and 2.6 over the 30-hp ceiling of the small Woodland chippers. That leaves WC68 and the WoodMaxx WM-8M and MX-9900 as the PTO-rated choices whose published minimums it clears. On the cab version, at 31.2 PTO hp, the WC88 gap grows to 3.8.
