A sulky apparatus for use behind self-propelled operator-controlled machines is provided. The apparatus includes a riding platform on which the operator stands, configured with a suspension system for absorption of shock and reduced impact on the body of the operator. The suspension system comprises one or more compression springs and is configured for dual adjustment, wherein the operator may adjust the spring tension directly by adjusting the compression of the spring coils or select pivot points on the sulky for control over the amount of load absorbed by the spring coils. The sulky apparatus may be connected to a self-propelled, operator-controlled machine by way of a boom system that attaches to the sulky apparatus at one end and the machine at the other. The sulky apparatus provides a significant benefit to the rider by way of suspension system capable of absorbing shocks to the rider, fitted within a limited space.
