The New Holland Boomer 40D CVT, Boomer 45D CVT and Boomer 50D CVT compact tractors are designed to deliver the maneuverability of a compact machine with the performance required for demanding property maintenance, landscaping, municipal work and light agricultural applications.

When these systems require professional repairs, the OEM Factory Repair Service Manual (Publication 47975091) provides dealership-level service information, detailed specifications, diagnostic procedures and step-by-step repair instructions to restore the tractor to factory operating condition.
