The Pro-Roll 120 is designed to adapt to your changing turf conditions. For hard packed fairways or athletic fields with divots, a heavier roller is desired. On rain soaked or newly sodded areas, lighter compaction is essential. The Pro-Roll 120 can easily accommodate these different demands, and everything in between!
To adjust compaction, each roller assembly can have up to four 30 lb 'suitcase' style steel weights as ballast. These weights can be added or removed as required from each roller assembly so each roller always has the same level of compaction. Removable weights allow the compaction (ground pressure) to be set between 5.8 and 9.7 psi and it is applied across the entire width of each roller. (For comparison: an average man of medium build excerpts a compaction of 8 psi while standing, and 16 psi while walking, which is localized to his footprint).
The advantage of using solid ballast is that exactly the same amount of compaction is applied to each roller, across the entire width of the Pro-Roll 120, regardless of the terrain. This eliminates compaction variability between rollers that is associated with other ballast methods. Importantly, no time or resource is wasted filling or draining water tanks! Additionally, using up to four easily handled 30 lb metal weights on each roller for ballast eliminates the need for a constant down pressure hydraulic system and the associated risk that a turf killing oil leak could occur.
