I have a 36V Ryobi Pole pruner unit. Also have the 36V hedge trimmer unit which can do body height hedging. Wanting to know if there is a compatible 36V pole hedge trimmer unit I can use in lieu of pole pruner when needed. Find that pruner does not do the job on thinner tree growth needing to be trimmed.. Noted there is a 18V unit however would prefer 36V if unit available.
