Stens OEM Replacement Belt for Bush Hog ATH 720, RDTH 72 Finish mowers 88843

What It Is

This is a replacement belt for Bush Hog ATH 720 and RDTH 72 finish mowers (72-inch deck models). It drives the spindle and blade system, and is designed for mowing large, flat turf areas like sports fields, parks, and estates.

Fitment & Compatibility

Before buying, confirm your mower model is exactly Bush Hog ATH 720 or RDTH 72 – this belt will not fit other Bush Hog models or decks. Check your old belt’s part number; the Stens 88843 replaces OEM Bush Hog part 88843 (often stamped on the belt itself). Measure your existing belt: it should be 1/2-inch wide and approximately 135 inches long (exact length varies slightly by tension, but this is the spec). Verify your deck is a 72-inch finish mower – not a rough-cut or zero-turn model. If your mower has a different deck size or belt width, this won’t work.

Key Things to Know

• Quality: Stens is a well-known aftermarket brand – expect OEM-equivalent durability. The 5.0 rating suggests consistent performance.
• Installation: Moderate difficulty. You’ll need to remove the deck or belt guard, release tension (often via a spring-loaded idler pulley), and route the belt per the diagram. A belt tension gauge helps avoid slipping or premature wear.
• Gotcha: The belt is Kevlar-reinforced – it’s tough but can be stiff when new. Run the mower for 10–15 minutes under light load to seat it. Check tension after the first hour.
• Common issue: If your deck has a damaged pulley or spindle bearing, the belt will wear quickly. Inspect pulleys for wobble or roughness before installing.

Should You Buy It

If you own a Bush Hog ATH 720 or RDTH 72 finish mower and need a reliable, direct-fit replacement, this Stens belt is a solid choice. It’s priced competitively, has strong user feedback, and matches OEM specs – ideal for both DIY homeowners and commercial operators. Skip it if your mower is a different model or deck size.
