Exmark acquired L.T. Rich Products, known for its Z-Spray line of stand-on spreader/sprayers and aerators for landscape contractors and grounds professionals. We are now able to offer Z-Spray parts through Exmark. Parts are slowly being converted over to Exmark part numbers if you do not see a part you need or have a question. Please call us 800 305 9255 or send us an email.
