32” Tomahawk – This size should be specified for the majority of trees with root ball depths up to and including 24 inches.  Varieties known to be extremely top heavy such as Pyrus calleryana ‘Bradford’ – ‘Bradford’ Callery Pear and most Gleditisia – Honeylocust varieties may need to be installed using one size larger.  The same rules regarding soil types as stated above with the 24” Tomahawk applies.  Once again, using the caliper method all trees from the 1.75” up to and including the non-top heavy 3.5” caliper trees can be installed with this size.

42” Tomahawk – This size will handle all root balls up to and including 36 inches in depth.  The same rules and suggestions especially those comments about top-heavy varieties apply to this size.  Depending on the geometry of the earth ball, consideration to specify or use 3 Tomahawks per should be considered.  This size should handle most varieties up to 5” caliper.
