Hi Millsi,

Here is the illustrated parts list for your engine:

Here is the operator's manual:

I've never seen a repair manual for any Greenfield product, but I've seen excellent owner manuals for a couple of Evolution models, running to 20-odd pages and showing how to do most things that might be necessary, including a number of complete pages on replacing and adjusting belts. However those are later machines than your Tractor 10. Although Greenfield's basic design has stayed much the same, a lot of specifics have changed along the way.

I suggest you begin by looking in detail at what Greenfield has supplied to you. If it is a short owner manual rather than a long one, the first step would be to go back to Greenfield and see what they can do to help you with more information.

Failure to climb when moving forward with a Greenfield often means the automatic tensioner on the wheel-drive belt has failed to click into the next latching point. It happens fairly frequently, and is overcome by pulling or levering the tensioner pulley under the seat into the next click position:

The automatic tensioner pulley is the one at the top of the picture, and moves further toward the top of the picture to increase belt tension.

Of course it is also possible that the forward clutch is worn or requires adjustment. Also, we have had a case where the automatic tensioner's ratchet was worn, causing it to fail to engage. You might care to read this thread:

Note that both belts on a Greenfield pass over idler pulleys that twist the belts 90 degrees, because of the tortuous path the belts follow. It does not seem to be harmful to the belts.
