Rhin-O-Tuff was founded and developed by Marvin Whiteman Jr., on the premise that no significant improvement had been made on the power trowel’s original design since it was invented and perfected by his father and himself over 40 years ago.

Some of the key innovations / improvements that have been incorporated into the Rhin-O-Tuff design are:

• Patented vibration dampening handle – For increased productivity and extended compliance with international vibration exposure standards.
• Blade Pitch Handle – Unique innovation for producing quality finishes.
• Gearbox Redesign – Ensures cooler operating temperatures and more efficient energy transfer for extended life / lower maintenance.
• Clutch – Spring loaded design for reduced belt wear.
• Belt Cover - Easy access to maintenance area.
• Bushings - Rotating wear parts are bushed for extended life and complete reconditioning.
