Cub Cadet 1720 Parts Catalog – 76 Pages of Factory Diagrams

Nothing burns through shop time faster than ordering the wrong part because the online listing was vague. You pull the air cleaner, measure the element, cross-reference three different websites, and still end up with a seal that doesn’t fit. That’s why I keep a Cub Cadet 1720 Parts Catalog on the bench – 76 pages of factory-sourced exploded diagrams, part numbers, and hardware callouts that match exactly what came from the factory. No third-party reprints, no blurry scans, no “this might fit” nonsense. If you’re working on a 1720 with serial number between 147,088 and 207,400, this is the document that tells you what goes where and what to order.

Parts Catalog: What’s Inside the 76 Pages

This isn’t a repair manual. It’s a parts catalog – meaning every page is a parts breakdown with reference numbers, part descriptions, and quantities. Page 1 shows the air cleaner assembly: the nut (KH-X-276-7), the cover, the precleaner, the element (759-3359), and the base. You see exactly which screws (10-32 x 9/16, hex wash head) and which gaskets you need. Page 3 jumps into the brake pedal and connections: pedal pad (735-0189), brake pedal (703-1532), parking brake bracket, springs, washers, cotter pins. If you’re rebuilding the brake linkage, you get every single nut, lock washer, and ferrule called out. No hunting through a generic diagram – it’s all right there.

Brake Pedal Assembly: Exploded View and Part Numbers

Take the brake system. The exploded view on page 3 lists 35 distinct items. You’ve got the brake cam (703-1558A), the brake rod (747-3131), a compression spring (732-0330, .58 OD x 2.00 Lg), a spiral spring pin, three cotter pins, and a switch actuator bracket for tractors with serial number 170,600 and above. The parts catalog gives you the exact part number from Cub Cadet’s system – not a re-numbered aftermarket equivalent that might be one thread pitch off. You order the part, it arrives, and it fits. That’s the value of a factory-sourced document.

Why a Factory Parts Catalog Over Aftermarket?

Aftermarket parts catalogs – the ones you find on forums or third-party sites – often combine multiple serial number ranges into one block diagram. They drop a washer or swap a screw size because “it’s close enough.” This catalog is split by serial number range: 147,088 – 207,400. If your tractor falls in that range, every part number listed is the one that came on it from the factory. I’ve seen aftermarket manuals list a flat washer when the factory used a wave washer; the difference matters for parking brake tension. The Automotive Industry Overview shows how precision in part sourcing keeps equipment running – and this catalog delivers that precision.

Air Cleaner Section: A Closer Look at Page 1

Page 1 covers the air cleaner assembly with 16 reference numbers. The precleaner (KH-45-083-01) sits inside the cover, and the element (759-3359) is a serviceable part – you replace it, not rebuild it. The elbow includes the gasket (KH-25-041-06) and a self-tapping screw (KH-52-086-11). The catalog notes which parts are service items (S) and which are replaceable (P). If you’re doing a full air cleaner overhaul, you need the cover, the seal, the base gasket, and the elbow. All listed with part numbers you can hand to a dealer or enter into an online search. No guessing which bolt pattern matches.

3 Use Cases for This Parts Catalog

First, ordering parts. You pull the diagram, find the reference number, read the part number, and order. Second, verifying what someone else installed. If you bought a used 1720 and the previous owner “fixed” the brakes with random hardware, the catalog shows you what should be there. Third, inventory management. If you’re rebuilding multiple units, you can create a master parts list from the catalog and stock what fails most often – like the air filter element or the parking brake grip.

Does this catalog include torque specs or repair procedures?

No. This is a parts catalog – 76 pages of exploded diagrams and part numbers. It does not contain repair instructions, torque values, or maintenance schedules. For repair procedures, you need a service manual.

What serial number range does this cover?

It covers Cub Cadet 1720 tractors with serial numbers 147,088 through 207,400. If your tractor falls outside that range, some components may differ. Check the decals on your frame for the serial number before ordering parts from this catalog.

When I’m elbow-deep in a mower deck or chasing a brake drag, I don’t have time to cross-reference part numbers from three websites. Having the factory diagram on the screen means I look up the part, order it, and move on. That’s why this 76-page PDF stays open on my tablet while I work.
