Bob,
Just a reminder that when you or anyone else is driving the Ventrac with the mower deck attached, make sure that the Weight Transfer System is engaged and set for the Maximum Transfer. You first raise the deck fully, set the amount of "strength" of transfer (usually maximum), and then lower the deck. Easy to do but also easy to forget for those unaccustomed to operating a tractor with a weight transfer system. You will be amazed at the effectiveness of this system in increasing traction and steering control on slopes.
Then on the other side, if you remove the deck in preparation for connecting another attachment, be sure to first raise the deck fully, disengage the weight transfer system, lower the deck, and then disconnect. It is physically possible to disconnect while leaving the Weight Transfer Engaged, but the lift arms will tend to snap up. Then when you approach another attachment, you will find it difficult to get the lift arms to lower and stay down to complete the connection.
After connecting and disconnecting a few times, this will become second nature to you. However, in the beginning, you may tend to forget when connecting or disconnecting. If you do forget to engage weight transfer, the tractor / deck system will tell you by its less than stellar performance on slopes.
If you haven't done so already, get the video or DVD from Venture Products that shows all of the equipment in operation. It is very well done. There are separate videos for the 3000 and 4000 series, but the DVD contains both.
Let us know how it comes out.
