Most machines come standard with mount brackets for the thumb kits hydraulic cylinder. Some older machines do not already have these mounts welded onto their sticks. We do make factory style cylinder mounts,  for John  Deere, Kubota, Bobcat & TB style machines. The mount brackets do require welding to attach to your machines stick.

This measurement is important for determining if a thumb will fit your machine. If you are unsure if a RCM thumb kit will fit, contact us with your make, model, and width of your machine. This measurement is also used for custom orders.

Due to the main pins added length and leverage, it is more likely to break. For this reason we do not provide center drilled main pins. Not drilling the main pin increases the life of the pin but it will still require a way to be greased. To extend the life of your new thumb assembly.

We recommend installing a grease fitting in the center of the main stick; drill, tap, and insert a grease fitting at this location. See our example video on how to do this.

A  quick connect bucket system allows you to simply pull a small pin/bolt and roll out of your buckets or attachments without having to remove your main pin, located at the end of your stick. 

Standard pinned on buckets  require you to remove the main pin from the end of your stick to switch or remove buckets.
