Introducing the VRM Super Hi Inertia Vertical Wood Hog, from Rawlings Manufacturing, Inc. No cookie cutter machine can meet everyone’s space constraints or challenges. We have had several customers over the years that wanted a Rawlings solid rotary hog but did not have the overhead clearance in their existing footprint to allow for a clam shell opening type of machine. The VRM hog opens hydraulically from the rear of the machine allowing full access to the hog’s internal wear components and rotor for ease of maintenance. All Rawlings Hogs are equipped with our Patented Super Hi-Inertia Rotor that powers through feed surges with ease while still running at lower RPMs than all other machines on the market. This saves our customers both maintenance and electricity costs. With over 40 years of experience in the forest and sawmill related industries, Rawlings delivers custom wood grinding equipment with a reputation for durability, performance and reliability. Since 1976 Rawlings Manufacturing, Inc. has been manufacturing and installing custom wood grinding systems. Rawlings offers a complete line up of wood grinders in a full range of sizes and models. Each customer's operation is unique with its own challenges. Our team designs each system specific to the customer's operation and specification. Add a wide variety of available options such as work platform decks, choice of belt, chain, vibrating in-feed and out-feed conveyors, metal, or magnet protection, product screening and separation, and you’ve got the flexibility to customize the perfect wood grinding system.

Rawlings 24/7 Customer Service
First off, I wanted to thank you again for your help with our hog issues. Yourselves and Rawlings as a company have proven to be about as reliable and helpful as any company I have dealt with in my 12 years in this job, so thanks for that. The mill manager was more than happy with the fact that, even with a late Friday afternoon start typical!, you were able to have parts to us from all over the map by the following Thursday and he's not easy to please. Hopefully we do't go through that again, but I look forward to any dealings I do have with you in the future.


Parts Maintenance
Sometime in early 2006, we changed to the new round style Hi-inertia rotor with Rawlings RocWear system. The only parts we have to change out are the Z-197 striker bits and fasteners. We used to go about 2 to 3 months or so before having to rotate the bits and the same to changing them out. To date, we seem to be getting about 2 to 3 times the life with the new style bits. Compare this to other hogs we have had were maintained at least weekly and you will see there is no comparison at all.

Rawlings Upgrade
When the decision was made to upgrade our hog, we considered several options but had heard that the Rawlings hog had superior result when compared to other hogs once considered. The decision was easy as soon as we evaluated our options. Since the upgrade, we have realized many returns that we had hoped for, specifically, to keep the hog running a full shift without a problematic shut down. That factor alone has increased our uptime. Prior to the upgrade, the barker needed to run on lower pressures to reduce chances of plugging the hog. To summarize, the return on investment that we expected has been greatly increased and I would not hesitate to recommend to anyone to invest in a Rawlings Hog system.
