Selecting the Correct Tine
There are several important characteristics that one
should keep in mind when deciding which JRM tine to
order. Most JRM tines when compared to comparable OEM
tines have a wall that is slightly thicker. This is
necessary to provide the extra wear. In the design process
it was decided that about 1/3 of the additional wall
thickness would be distributed to the ID (Inside Diameter)
and the remaining 2/3rds would go to the OD (Outside
Diameter). These ratios vary slightly from tine to tine,
but the principle is true of most JRM conventional tines.
Because of the increased wall thickness and the resulting
smaller core diameter (ID), it is often desirable to
select a JRM tine that is listed as one size above the
OEM tine you have historically used. For example, instead
of a 1/2” OEM coring tine one might wish to use a 5/8”
In selecting the proper JRM tine you must first know the following:
- Maximum length tine that your machine will accept (this information should be available from the manufacturer.)
- The mount size (in inches) of the tine holder--you may also simply mea sure one of the tines you are presently using. [Most manufacturers offer several options when a new machine is purchased.]
- What is the soil composition you are likely to be
encountering...if you are likely to encounter (rocks,
push-up greens, or USGA spec soil). A top eject coring
tine is structurally stronger than a side-eject coring
- Is your aerification machine setup with the proper timing?
- Carefully check the ID of the tine you are considering since this will be the core size with coring tines.
