Amazing

👍

About halfway there…….

Like most apps I have used on Apple devices this one gets the ball to the ten yard line and falls short of ever getting the job done. The android version works much faster and better. This version looses the data every time the screen locks and is very slow about reloading the data. Also some data is not available here. Every engine’s data from at least 1995 should be able to obtained in short order to live up to the level of service we expect.

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.

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.
