Key Features
- Genuine OEM Construction — Manufactured to the same material grade and dimensional tolerances as the original belt guard side plate, ensuring proper enclosure and coverage of the drive belt.
- Direct-Fit Installation — Mounts to the existing guard hardware on compatible trowels using the original bolt pattern, eliminating the need for any modification or trimming.
- Broad Ride-On Trowel Compatibility — Confirmed fitment for HHN34TVD, HTN-31VTCSL5, and HTO-31VTCSL5 mechanical ride-on trowel models.
- Drive Belt Protection — Fully encloses the belt drive system to shield it from concrete slurry, debris, and impact damage that can shorten belt life and cause premature drivetrain wear.
- Operator Safety Compliance — Replacing a cracked, missing, or damaged belt guard side plate restores the protective barrier required to keep rotating drive components safely enclosed during operation.
The belt guard side plate forms part of the protective enclosure surrounding the drive belt on mechanical ride-on power trowels. Its job is to contain the belt within a defined channel, shielding it from concrete debris, moisture, and accidental contact that can cause rapid wear or catastrophic belt failure mid-pour. When this plate is cracked, broken, or missing, the exposed belt is vulnerable to fouling and damage, and the machine presents a rotating-component hazard to the operator and crew. Keeping the guard assembly intact is essential to both the longevity of the drivetrain and safe trowel operation on the slab.
