Tractor and Ty – Crop work well together when fairways need to be topdressed. Also does a great job with the ProPass when all the greens need sand. You fill the Ty – Crop with sand which holds approximately 4 yards then take it out to the course and park in a location that is some what central to 3 or 4 greens. Ty –Crop rear can be raised up and the ProPass backed in to be filled with sand. The ProPass holds 1 yard of sand and depending on the setting can topdress 2 to 3 greens. Then all equipment is moved onto the next group of greens and so on. By doing this the green staff can hustle through all 18 greens.
