The Bartell B436 Pro Series Trowel has been the staple for concrete finishers around the world due to its quality and balance. The gearbox and spider assembly have changed little over the past 70 years and continue to be one of the most reliable units on the market.
All trowels are manufactured from heavy gauge steel and jig welded to ensure complete rigidity.
The gearbox and spider design is where Bartell Pro series excel. Gearboxes are produced from Precision machined aluminum and contain heavy-duty bronze and steel worm gears. The spider design uses matched tolerances between the hub and arms to ensure no flex. This design keeps the trowel blades down firmly to eliminate high spots fast. Production rates are the result.
