Just terrible

You have to include all power plants in the database. If you are going to sell replacement parts from John Deere I can use in my tractor, than you need to include them in this app.

You can’t tell me to contact Yanmar...JD used a BUNCH of these motors in their tractors and has no problem selling replacement parts for them.

This is an absolutely outstanding resource for a Technician

One of the biggest struggles is finding either the correct CTM manual for use with diagnostics or the correct part based on build codes. This app solves both those problems as well as providing additional diagnostic resource information. The direct link to the correct parts book along with the as ordered build codes makes getting the correct part a synch.

As others have stated this app does not support the Yanmar engines. In my opinion that is to be expected as Yanmar should offer a similar app for their own engines.

If you're going to make an App make sure your entire database infrastructure contains your customer's serial numbers including those you have installed in the tractors you sell regardless of who manufacturers them. If it says John Deere it's a John Deere not a Yanmar!
