John Deere: Which Parts to Replace with Polyurethane and How Much You'll Save

Author: Yehor Medunytsia · 08.05.2026

Short answer: For John Deere equipment, the parts most commonly replaced with polyurethane are straw walker bushings, cab suspension mounts, and driveshaft components. PolyPro polyurethane parts last 3–5 times longer than standard rubber ones — and hold up to the aggressive loads of field conditions without losing elasticity or performance.

Why Standard Rubber John Deere Parts Wear Out Quickly

John Deere equipment operates in conditions very different from a passenger car: dust, moisture, sharp temperature swings, and constant impact and cyclic loads on the machine's components. Standard rubber parts are designed for typical conditions and wear out in 1–3 seasons depending on how intensively the equipment is used.

Polyurethane as a material is more resistant to abrasive wear, oils, fuel, and a wide temperature range. Where a rubber part starts to fail after a single season, a polyurethane one holds up for 3–5 seasons without replacement. For a detailed comparison of the materials, see: Polyurethane vs Rubber Bushings: An Honest Comparison for Your Car.

Straw Walker Bushings for John Deere: The First Part to Replace

The straw walker is one of the most heavily loaded assemblies on a John Deere grain combine. Straw walker bushings endure constant cyclic impact loads throughout the entire field season. Rubber parts in this assembly are the part PolyPro replaces most often.

The polyurethane straw walker arm bushing for John Deere is a part with a polyurethane insert bonded to a metal sleeve. The load is distributed evenly, with no risk of the liner separating from the metal. Service life is 3–5 times longer than rubber parts.

The polyurethane part isn't affected by grease, dust, or moisture — the exact conditions where rubber degrades fastest. That's why the polyurethane John Deere straw walker bushing is the first recommended position for switching to polyurethane on this brand of equipment.

Cab Suspension and Driveshaft Components for John Deere

John Deere cab suspension mounts — the assembly where rubber mounts damp vibration from the running gear and engine. Worn mounts transmit vibration straight into the cab — the operator tires faster, and long hours in the field become uncomfortable. PolyPro polyurethane cab suspension mounts damp vibration just as effectively, but last 3–5 times longer.

John Deere driveshafts and support bearings — another area where polyurethane saves money. Rubber couplings and driveshaft support bearing bushings on combines wear out in 1–2 seasons. A polyurethane part holds up for 4–6 seasons under comparable loads. PolyPro manufactures polyurethane parts for these assemblies from a sample or a technical drawing.

How Much Polyurethane Saves: A Cost Calculation for John Deere

A typical calculation for a single part:

Part Rubber Polyurethane PolyPro Savings over 6 seasons
Straw walker bushing 400 UAH × 3 replacements = 1,200 UAH 700 UAH × 1 replacement = 700 UAH 500 UAH
Cab suspension mount 600 UAH × 3 replacements = 1,800 UAH 1,000 UAH × 1 replacement = 1,000 UAH 800 UAH

The difference on a single part over 6 seasons is 500–800 UAH. On a machine like a John Deere combine, which has 8–20 such assemblies, that adds up to 4,000–16,000 UAH in real savings — not counting labor costs for each replacement.

Paying twice as much for polyurethane once is significantly more cost-effective than replacing a rubber part three times over the same period. That's why agricultural businesses that track maintenance costs switch to polyurethane systematically.
