Erwin G. Martin of 323 Hartings Park Road in Denver, Pennsylvania 17517 is the creator of this OilPull model now in the collection of his son-in-law Larry Groff.

I heard this loud 'per-lump, per-lump' in the distance and I said to my grandfather, 'That's not a John Deere; but what is it?' He said, 'That's an OilPull tractor; let's go find it.'

We got the model T Ford truck out and went in the direction of the sound. This was my first experience seeing a 45 HP OilPull turning a threshing machine. Did you ever stand watching a large tractor labor, and then get all goose-bumpy?

Prior to this, I was always used to our 10-20 Titan tractor, but now the OilPull took first place in my life. From then on, the Rumely was my favorite tractor. I told my grandfather 'When I grow up, I'm going to have an OilPull tractor.'

Well, plans, wishes, or desires don't always turn out as expected. After high school, I landed in a large sewing factory as a sewing machine mechanic.

After 45 years, sure enough, the Rumely desire returned again. Now retired, and with plenty of time on my hands, I decided to build my own Rumely OilPull.

I started making blue prints and searching for proper parts, etc. One day my wife said, 'I think you're a little 'per-lump' in your head!'

But when determination takes over, you go places. I bought a 3 HP International single cylinder engine. I knew I needed the constant fire type for the proper sound. Next was the proper transmission. I used a 2-speed Handiman garden tractor transmission, which worked out just fine. Then came the front wheels, axle, and steering system, which came from a 20 HP Wheel Horse tractor. Next, were the rear wheels which were skid loader wheels.

The most complicated thing was the Rumely stack, or exhaust system. I took pictures of the original tractors and went off for help. A local metal and tinsmith shop did a beautiful job for me. All this took approximately two years to get everything together.

Now building the tractor; what a job-but all a pleasure! I used four inch angle iron for the frame. Now, with all the component parts working together, I had my own Rumely OilPull.

With the Rumely hooked to a rather large air compressor, using a four inch flat belt, we get lots of attention and enjoyment at the various tractor shows.

I'll share this show experience with you. I always take extra folding chairs along with me. People get very tired just walking and walking around shows.

Several of us were sitting there sharing when a gentleman came along and just stood there watching the OilPull puffing away, turning the air compressor. He gave the tractor a thorough examination; then he looked over at us sitting on the chairs. I got up and walked over and immediately he said, 'Is this your outfit?' I said, 'Yes.' 'Do you wish to sell it?' My reply was, 'I was never asked before, but I'll share this with you. I have $3000 tied up in the tractor alone.' His reply was, 'I'll give you a check right now, okay?' 'Sorry, not for sale right now.' His reply was, 'when it is, please call me; here is my phone number.'

Well, when my family found that out, I got several sobering instructions: 'That tractor stays in the family!'

My son-in-law, Larry L. Groff, is now owner of the tractor.
