Massey Harris Puller

Alright guys. I have a 44 special puller that I can pull in the 4500 and have been hitting the 270ft mark. I am turning about 1800 RPM. But really want to be getting out to the 300 ft mark. Kind of struggling on what to do next to let people take notice that there is Massey to play with now. I know horsepower doesn't always win the race.
 
Without knowing your class or the regulations governing it, a slower ground speed could help if traction is not an issue....lower profile rear tire, a longer drawbar may also help.

Why are you stopping at 270ft? Lack of traction or lack of power? What type of track (sandy, clay)? Do you have rpm limits or speed limits?
 
spinning out or powering out? i pull a 44 special and do very will. tires make a world of difference
 


We are spinning out. We are running first gear around 1800 rpms. Holding the power all the way down the track. But spinning out and not able to let the tractor lug out. Currently have 14.9x38's Goodyear on there now. Even running a low air pressure and still won't bit. This weekend was a hard teack. Like way hard. Other times not so hard.
 
A couple of things to try. Move more weight to the back if the nose is staying on the ground. Make sure that your drawbar is as short and as high as the rules will allow. The harder the track, the higher the air pressure. Are your tires cut or not?
If not, load the tractor up heavy and take it out on the road to get some road wear on the tires (if you live in a rural area). Twenty-three degree tires generally work better in more places, but I've had success with 45 deg tread as well on certain tracks. Good luck!
 
Wouldn't a longer drawbar give you more weight transfer? Think of the tractor as a lever, with the tires the fulcrum, the front end the load and the end of the drawbar where the effort is ---maybe we should have the experts solve this one---Mythbusters of course!!

Mecanically, hooking further back will give you more weight transfer to the rear.
But the chain of the sled being a given, it is an advantage to run it as vertical as possible, so the higher the hook is, the highest angle you will get. If very haigh and very far back are not possible at the same time, very high is probably the better choice.
My 44 has 16.9-34, this should get more traction, right?
