Situation:

Some customers may experience broken or damaged reels or bedknives on EdgeSeries

Reelmaster cutting units. After investigating various failures, we have identified two main

symptoms:

• EdgeSeries reel damage to the reel blade(s)

• EdgeMax inserts coming loose

EdgeSeries Reels: Our investigation revealed that Forward Swept Reels (FSR) are

more susceptible to damage when contacting foreign objects. Contact will create a

condition where the bedknife is forced into the reel while turning, causing damage to the

reel blades, weldments and bedknife. The EdgeSeries FSRs have a more aggressive

blade angle, which provides better edge retention but also makes it more likely that the

reel could catch on the bedknife if there is contact with foreign objects.

EdgeMax Bedknives: Bedknife inserts can become damaged for a variety of reasons as

well. The most common reasons are contacting foreign objects (or impacts), excessive

bedknife grinding and general wear or worn past the service limit.

Action Required: Review and understand the content in this bulletin EdgeSeries Reels: 1. Verify proper reel and bedknife maintenance as outlined in the Operator’s Manual 2. A lead-in chamfer is required to help prevent damage to bedknife and/or reel. Refer to the Operator’s Manual and Figure 5 for more details. 3. The FSR design is more prone to damage since the reel outside diameter “grows” during impact conditions versus the radial reel design, and thus having a lead-in chamfer is more important.

Figure 2 1 - Typical Bedknife Damage This figure shows the insert has been pulled out of the knife from the impact with the reel. The bedknife may be bent upward and inward as well.

Figure 5 Notice the lead in chamfer on the leading edge of the bedknife. The lead-in chamfer helps to ensure the reel blade is forced over the bedknife even if the knife is deflected up slightly.
