The CK3520 manual produces 30.9 PTO hp while CK3520H produces 28.9. That gap straddles the 30 PTO-hp ceiling on two researched chippers, giving transmission a direct effect on the shortlist.

PTO WOOD CHIPPERS FOR THE CK3520
Chippers that fit the CK3520.
13 of 19 pto wood chippers we track pass the published power, hitch and speed screen on at least one configuration. Each still has a detail to confirm with the seller.
19 of 23 flail mowers we track pass the published power, hitch and speed screen on at least one configuration. Each still has a detail to confirm with the seller.
Scope of this guideManual / HST, three ranges. Each configuration below states the model and equipment covered by its sources.
Check maximum power as carefully as minimum power.
The manual CK3520 delivers a published 30.9 PTO hp; CK3520H hydrostatic delivers 28.9 PTO hp. A 30 PTO-hp lower limit therefore splits the two configurations.
Upper limits matter too: the currently researched Woodland Mills WC46 and TFG55 list a 30 PTO-hp ceiling. The manual's 30.9 is above that ceiling; do not round it down to create a match.
The CK3520H's 28.9 PTO hp is below a 30 PTO-hp minimum even though the engine is labeled 34.9 gross hp. A seller's ambiguous 30–60 tractor-hp label must remain unresolved.
The 1,631 lb rating is measured 24 inches behind the hitch. More PTO power than a Kubota L3302 does not remove ballast, overhang or axle-load checks.
The base CK3520/CK3520H is distinct from CK3520SE and CK3520SEH. The brochure gives base CK20 live PTO and optional remotes; do not import the SE's independent-PTO or standard-valve specification.
Choose the exact configuration.

Current base-model webpage says 12 forward / 12 reverse; current linked base CK20 brochure says 9F/3R. The brochure's SE row separately says 12 x 12.
Use Manual as the transmission label, omit a verified gear count, and retain exact model/serial check. Do not assume the webpage is the SE variant.
steering and clutch descriptions
Some current HST/CK3520 web tables label steering Mechanical while the brochure says Hydraulic Power Steering; brochure merges Dry Dual Stage clutch across base models while HST web pages say Dry Single Stage.
Do not publish steering/clutch specifics as verified in this batch. These inconsistencies do not change the corroborated PTO horsepower and hitch-category facts.
