We have a 2007 Model 232 Pro Vac for sale. It came off my 757 Z-trak but will fit 737-797 also. It was used maybe 4 times we no longer offer bagging as a service so I have no need for it. This unit would with minor modifications fit most any brand or model mower. Would be great for walk behind also. For more information go to Proteroinc.com or call the factory at 763-535-4038. $550.00 call with questions 269-641-7420.
